Quick Start

API Keys

You need a Loqate API key for verification. Optionally, an Anthropic API key for the parse command.

macOS / Linux:

export LOQATE_API_KEY=your-key-here

# Optional — for lqt parse
export ANTHROPIC_API_KEY=your-key-here

Windows (PowerShell):

$env:LOQATE_API_KEY="your-key-here"

# Optional — for lqt parse
$env:ANTHROPIC_API_KEY="your-key-here"

Your First Verification

macOS / Linux:

# Verify an address
lqt verify --address "125 Summer Street, Boston, MA 02110, US"

# Verify address + email + phone with a policy
lqt verify -a "10 Downing St, London, GB" \
           -e "pm@gov.uk" \
           -p "+442071234567" \
           --policy shipping

# Parse and standardize without calling Loqate (uses Claude)
lqt parse --address "125 summer street boston ma 02110 us"

Windows (PowerShell):

# Verify an address
.\lqt.exe verify --address "125 Summer Street, Boston, MA 02110, US"

# Verify address + email + phone with a policy
.\lqt.exe verify -a "10 Downing St, London, GB" -e "pm@gov.uk" -p "+442071234567" --policy shipping

Address suggestions (--suggest)

Licensing. Suggestions use a Loqate feature that is licensed separately from address verification and must be enabled on your account. If it isn't, nothing breaks: the verification still returns its normal result and exit code, and the reason appears in suggestions.error (typically an unknown-key or licence message from Loqate). Talk to your Loqate account contact to have it enabled.

Verification tells you an address is wrong. Suggestions tell you what the right one probably is. Add --suggest and lqt asks Loqate for real addresses matching what was typed, returning them with the decision.

The lookup runs when either:

1. the address was not accepted (review or reject), or
2. the address was accepted but scored below the policy's suggestion floor (0.85 on standard — see the Policies table).

The second case is the one that catches near-misses. A policy accepts anything at or above its minimum confidence, so accepted is not the same as confident: on standard the input marsh wall, E14 9TN matches a street and scores exactly 0.55, which is accepted — yet the house number is missing and better addresses exist. Use --suggest-below to move that line (--suggest-below 0 turns the confidence check off and only suggests on review/reject).

{
  "address": {
    "verified_address": "Downing Street, London",
    "confidence": 0.5,
    "recommendation": "review",
    "suggestions": {
      "requested": true,
      "triggered": true,
      "reason": "accepted but confidence 0.55 is below the 0.85 floor",
      "floor": 0.85,
      "source": "loqate",
      "count": 2,
      "items": [
        {
          "id": "GB|RM|A|52509479",
          "type": "Address",
          "text": "10 Downing Street",
          "description": "London, SW1A 2AA",
          "address": "10 Downing Street, London, SW1A 2AA"
        },
        {
          "id": "GB|RM|A|52509480",
          "type": "Address",
          "text": "11 Downing Street",
          "description": "London, SW1A 2AB",
          "address": "11 Downing Street, London, SW1A 2AB"
        }
      ]
    }
  }
}

Things worth knowing:

• Off by default, so existing output is unchanged unless you ask for suggestions.
• No lookup for a confidently accepted address — you pay the extra latency only where it helps. The suggestions block is still returned with "triggered": false and a reason, so you can tell "no alternatives needed" from "suggestions were never requested".
• floor reports the threshold that was applied, so you can see why a lookup ran (or didn't) without knowing the policy's configuration.
• Suggestions never change the decision. If the lookup fails, the reason appears in suggestions.error and the verification result stands.
• Address-only. With verify --email / --phone, or verify_contact, only the address block is decorated.
• An entry with "expandable": true is a street, postcode, or building holding several addresses rather than one deliverable address. Search within it for a specific premise.
• Suggestion lookups do not consume Loqate verification credits, but the feature must be licensed on your account (see the note above).
• Suggestions need a standard Loqate key (--key / LOQATE_API_KEY); --verify-key alone covers address verification only.
• Not available with --batch. A large file would fan out into an unbounded number of lookups, so the combination is rejected. Verify the file, then re-run the flagged rows individually with --suggest.

Available on the MCP verify_address / verify_contact tools and the REST /v1/verify/address / /v1/verify/contact endpoints as suggest: true, with optional suggest_limit (1–10, default 5) and suggest_below (0–1).

Closing the loop: offer, choose, re-verify

A suggestion is a candidate, not a verdict. Items carry no confidence score, no match level, and no AVC — they are what the reference data thinks the address might have been. Don't write one into your system of record on faith. Close the loop in three steps:

1. Verify with --suggest. A non-empty suggestions.items means alternatives exist.
2. Offer items[].address to whoever can decide — the customer in a checkout or support flow, the agent in an automated one. That field is the ready-to-display line.
3. Confirm the choice by its id (--suggestion-id). That result — its confidence, match level, and standardized fields — is the one you keep. Full flow below.

# 1. verify, asking for alternatives
lqt verify -a "marsh wall, E14 9TN" -c GB --suggest -o json > result.json

# 2. show the candidates
jq -r '.address.suggestions.items[] | .address' result.json
#   1 Marsh Wall, London, E14 9TN
#   2 Marsh Wall, London, E14 9TN

# 3. re-verify the chosen one — this is the decision of record
lqt verify -a "1 Marsh Wall, London, E14 9TN" -c GB -o json

Over REST it's the same shape — one call with suggest, then a plain call with the choice:

curl -s -X POST https://your-host/v1/verify/address \
  -H "Authorization: Bearer $LOQATE_API_KEY" -H 'Content-Type: application/json' \
  -d '{"address":"marsh wall, E14 9TN","country":"GB","suggest":true}'

curl -s -X POST https://your-host/v1/verify/address \
  -H "Authorization: Bearer $LOQATE_API_KEY" -H 'Content-Type: application/json' \
  -d '{"address":"1 Marsh Wall, London, E14 9TN","country":"GB"}'

The full flow, end to end

1. Verify with --suggest — get candidates for an address that didn't come back clean.
2. Offer items[].address to whoever decides.
3. Confirm with --suggestion-id, using the chosen item's id. That result is the one you keep.

# 1 + 2
lqt verify -a "marsh wall london" -c GB --suggest -o json > r.json
jq -r '.address.suggestions.items[] | "\(.id)\t\(.address)"' r.json

# 3 — confirm the chosen one by id, not by re-typing the text
lqt verify --suggestion-id "GB|RM|B|55782678" -o json

Passing the id rather than the text is what makes step 3 accurate: lqt fetches that address's cleansed components (company, sub-building, number, street, city, postcode, country) and verifies those, so nothing is re-parsed. It matters for suggestions carrying a company name — London Lash, 56 Marsh Wall, London — where re-reading the text can misplace the company as part of the street.

The result records what it resolved from, so you can audit it without resolving again:

{
  "verified_address": "56 Marsh Wall, London, E14 9TP",
  "confidence": 0.95,
  "recommendation": "accept",
  "resolved_from": {
    "suggestion_id": "GB|RM|B|55782678",
    "address": "London Lash, Unit 7, Hampton Tower, 56 Marsh Wall, LONDON, E14 9TP"
  }
}

Over REST, the same two steps:

curl -s -X POST https://your-host/v1/verify/address \
  -H "Authorization: Bearer $LOQATE_API_KEY" -H 'Content-Type: application/json' \
  -d '{"address":"marsh wall london","country":"GB","suggest":true}'

curl -s -X POST https://your-host/v1/verify/address \
  -H "Authorization: Bearer $LOQATE_API_KEY" -H 'Content-Type: application/json' \
  -d '{"suggestion_id":"GB|RM|B|55782678"}'

What to know:

• Step 3 consumes a Loqate credit to resolve the id (the search in step 1 does not). Resolve the one address that was chosen — not the whole list to compare.
• suggestion_id replaces address; sending both is a 400.
• Not available with --batch, and not with --dry-run (resolving needs a live billable call).
• A stale id returns SUGGESTION_NOT_FOUND / 404. Ids change over time — search again rather than retrying the same id.

Just want the address, not a decision? Resolve it on its own:

lqt retrieve --id "GB|RM|B|55782678"           # components as JSON
lqt retrieve --id "GB|RM|B|55782678" -o table  # human-readable

GET /v1/address/{id} over REST, or the retrieve_address MCP tool. This returns reference data, not a verification — no confidence, no recommendation — so don't treat it as checked.

Four rules that keep the loop safe:

• Omit suggest on the confirmation call. If the chosen address still doesn't clear the policy you'd get a fresh set of suggestions, and an automated flow could bounce between them. One round of suggestions, then a plain verify.
• Let the re-verify decide — not the fact that a suggestion existed. If the confirmation returns review or reject, the record still needs a human. You've narrowed it, not fixed it.
• Don't re-verify an expandable item as-is. It's a street, postcode, or building, so verifying it lands at street level at best. Use it to ask for the missing piece ("which number on Marsh Wall?") and verify the completed address.
• Never store id. It's a Loqate-assigned identifier that changes over time. Key off the verified address returned in step 3.

Keep the country from the original request on the confirmation call — dropping it can change the match.

Suggestion ranking comes from Loqate

lqt returns suggestions in the order Loqate provides them — no re-ranking or filtering is applied. Loqate matches across the whole address record, including organisation names, so a query like marsh wall london ranks businesses with "London" in their name above plain residential addresses on that street:

London Lash, 56 Marsh Wall, London, E14 9TP
London Metropolis Ltd, 77 Marsh Wall, London, E14 9SH

That's standard address-autocomplete behaviour, but it means suggestion quality tracks input quality. Where you know the country, pass it as --country rather than leaving it in the address text — that moves the token out of the fuzzy match and into a filter:

lqt verify -a "marsh wall london" --suggest      # "london" is matchable text
lqt verify -a "marsh wall" -c GB --suggest       # cleaner: country is a filter

parse

Parse and standardize contact data using Claude (Haiku). Extracts address components, validates email syntax, and normalizes phone numbers with awareness of 250+ country-specific postal formats. No Loqate API calls — no credits spent.

lqt parse [flags]

Flags:

Examples:

# Parse a messy address into structured components
lqt parse -a "125 summer street boston ma 02110 us"

# Parse address + validate email + normalize phone
lqt parse -a "10 downing st london" -e "test@mailinator.com" -p "02071234567"

# Batch parse from CSV
lqt parse --batch messy-data.csv --output json

policy

List, inspect, and validate verification policies.

lqt policy list                  # List all built-in policies
lqt policy show <name>           # Show full JSON for a policy
lqt policy validate <file>       # Validate a custom policy JSON file

mcp

Start an MCP (Model Context Protocol) server. Exposes LQT as tools for AI agents.

lqt mcp                    # Stdio transport (launched by clients)
lqt mcp --http :8080       # HTTP transport (deployed as a service)
lqt mcp --smoke-test       # Verify the server starts correctly and exit

Flags:

REST API

For clients that don't speak MCP, the HTTP server can also expose a plain REST API — opt-in with --rest, mounted at /v1 on the same port. Same result data as the CLI and MCP.

lqt mcp --http :8080 --rest

Authentication: your Loqate API key as a bearer token — Authorization: Bearer <LOQATE_API_KEY> (or key in the request body).

A recommendation (accept / review / reject) is always returned as HTTP 200 with the decision in the body. Errors use standard status codes: 400 invalid input, 401 missing/invalid key, 429 rate limited, 502 upstream error.

curl -s -X POST https://your-host/v1/verify/address \
  -H "Authorization: Bearer $LOQATE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"address":"125 Summer St, Boston, MA 02110, US","policy":"standard"}'

# Ask for alternatives when the address does not clear the policy
curl -s -X POST https://your-host/v1/verify/address \
  -H "Authorization: Bearer $LOQATE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"address":"10 downin st london","country":"GB","suggest":true,"suggest_limit":5}'

Full request/response schemas are documented in the OpenAPI spec at /v1/openapi.json (browse it at /v1/docs).

Explaining a result

Every address verification also returns detail that explains the score without changing it:

To get changes, ask Loqate for its per-field status codes:

lqt verify -a "125 Summer St, Boston, MA 02110, US" \
  --option ServerOptions.FieldStatus=true -o json

"changes": [
  { "field": "country_name",            "change": "added",       "value": "United States", "code": "5" },
  { "field": "postal_code",             "change": "reformatted", "value": "02110-1634",    "code": "2" },
  { "field": "postal_code_secondary",   "change": "added",       "value": "1634",          "code": "5" },
  { "field": "sub_administrative_area", "change": "added",       "value": "Suffolk",       "code": "5" }
]

Nothing was wrong with that address; three things were added (ZIP+4, county, country name) and the postcode was reformatted. Fields Loqate verified without touching are not listed, so a short list means a clean address.

change is one of added, corrected, reformatted or unrecognised. code is Loqate's original status code, kept so the categorisation is not lossy — the codes are Loqate's own, documented at docs.loqate.com/report-codes/fieldstatus.

Absent changes means you did not ask for the codes. An empty array means you asked and nothing changed. The option also adds a <field>_status key per component to fields, since that passthrough returns everything Loqate sends.

This detail appears on every address verification — single, batch (per row), MCP and REST — because all four go through the same result builder.

Policies

Policies control what gets accepted, reviewed, or rejected. Every verification runs through a policy — there are no hardcoded thresholds.

Suggest Below is not an acceptance threshold — it never changes accept/review/reject. It is the confidence below which --suggest looks up alternatives even for an accepted address. See Address suggestions. Custom policies can set their own value, and the recommend_policy MCP tool proposes one for the use case you describe.

Custom Policies

Create a JSON file:

{
  "name": "my-custom-policy",
  "description": "Tuned for my use case",
  "address": {
    "min_confidence": 0.65,
    "min_match_level": "street",
    "reject_verification_status": ["U", "R"]
  },
  "email": {
    "min_confidence": 0.50,
    "allow_catch_all": true,
    "reject_disposable": true
  },
  "phone": {
    "min_confidence": 0.40,
    "required": false
  }
}

lqt policy validate my-policy.json    # Validate first
lqt verify -a "..." --policy-file my-policy.json

Batch Processing

Process files with address, email, and phone columns. Supports comma, tab, and pipe delimited input.

# CSV (auto-detected)
lqt verify --batch addresses.csv --policy shipping -o json > results.json

# Tab-delimited
lqt verify --batch addresses.tsv -o json

# Pipe-delimited
lqt verify --batch addresses.txt --delimiter pipe -o json

# From stdin
cat addresses.csv | lqt verify --batch - --policy standard

lqt verify --batch addresses.csv --summary

Windows (PowerShell):

.\lqt.exe verify --batch addresses.csv --policy shipping -o json > results.json
Get-Content addresses.csv | .\lqt.exe verify --batch - --policy standard

Delimiters

Auto-detected from the first line. Override explicitly with --delimiter:

MCP Integration

The lqt mcp command exposes LQT as tools for AI agents via the Model Context Protocol. Connecting the MCP server also provides a built-in usage guide prompt that teaches the AI how to use the tools effectively.

Claude Code / Cursor

Add to your project's .mcp.json:

{
  "mcpServers": {
    "loqate": {
      "command": "lqt",
      "args": ["mcp"],
      "env": {
        "LOQATE_API_KEY": "your-key-here",
        "ANTHROPIC_API_KEY": "your-key-here"
      }
    }
  }
}

Claude Desktop

Add to Claude Desktop's MCP settings:

{
  "mcpServers": {
    "lqt": {
      "command": "/usr/local/bin/lqt",
      "args": ["mcp"],
      "env": {
        "LOQATE_API_KEY": "your-key-here",
        "ANTHROPIC_API_KEY": "your-key-here"
      }
    }
  }
}

GBG-hosted endpoint (recommended)

The fastest way to use Loqate over MCP is the GBG-hosted endpoint — no install, no infrastructure. Point any MCP client at:

https://reach.prod.fabric.gbgplatforms.com/mcp

Claude Code / Cursor / any MCP client — .mcp.json:

{
  "mcpServers": {
    "loqate": {
      "url": "https://reach.prod.fabric.gbgplatforms.com/mcp"
    }
  }
}

Restart your client, then ask it to "verify 125 Summer St, Boston, MA 02110, US". It will discover the tools, call them, and explain the result.

Authenticate with your Loqate API key — pick one:

1. Per-call — pass key in the tool arguments ({"key": "YOUR-KEY", "address": "..."}).
2. Connection-wide — set Authorization: Bearer <YOUR-LOQATE-KEY> on the HTTP connection. Applies to every tool call.
3. Out of band (Claude only) — put <loqate_api_key>YOUR-KEY</loqate_api_key> in org / project / user instructions; the model injects it as key automatically.

If you supply none of the three, the server returns a NO_API_KEY error. The Bearer header only supplies the standard Loqate key; verify_key for a custom address-verify endpoint is separate.

Sanity check from your terminal (no client needed):

# List tools (no auth required)
curl -s -X POST https://reach.prod.fabric.gbgplatforms.com/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

# Verify an address (Bearer auth)
curl -s -X POST https://reach.prod.fabric.gbgplatforms.com/mcp \
  -H 'Authorization: Bearer YOUR-LOQATE-KEY' \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"verify_address","arguments":{"address":"125 Summer St, Boston, MA 02110, US"}}}'

Hosted deployments disable custom verify endpoints for security. If you receive a CUSTOM_ENDPOINT_DISABLED error, remove verify_url and verify_key from your tool arguments.

GBG-hosted REST endpoint

Prefer plain REST? The same hosted service also exposes the REST API — no MCP client required. Authenticate with your Loqate API key as a bearer token.

# Verify an address
curl -s -X POST https://reach.prod.fabric.gbgplatforms.com/v1/verify/address \
  -H 'Authorization: Bearer YOUR-LOQATE-KEY' \
  -H 'Content-Type: application/json' \
  -d '{"address":"125 Summer St, Boston, MA 02110, US","policy":"standard"}'

# Browse the interactive API reference (no key required)
open https://reach.prod.fabric.gbgplatforms.com/v1/docs

The OpenAPI spec (/v1/openapi.json) and reference page (/v1/docs) are unauthenticated, so you can explore the full API before you have a key.

Remote HTTP (self-hosted)

If you'd rather run the server yourself, deploy lqt mcp --http as a service:

{
  "mcpServers": {
    "loqate": {
      "url": "https://lqt.your-company.com/mcp"
    }
  }
}

Same three-tier key resolution applies (body key → Authorization: Bearer → server env LOQATE_API_KEY).

Available Tools

10 tools in stdio mode, 7 in HTTP mode (tools marked stdio mode only are not available over HTTP).

# Persistent (survives restarts)
[System.Environment]::SetEnvironmentVariable("LOQATE_API_KEY", "your-key-here", "User")

# Per-command flag
.\lqt.exe verify -a "..." --key your-key-here

Anthropic API Key (for parse)

macOS / Linux:

export ANTHROPIC_API_KEY=your-key-here

Windows (PowerShell):

$env:ANTHROPIC_API_KEY="your-key-here"

Resolution order: flag > environment variable > key file

Custom Verify Endpoint (optional)

If you need to route address verification through a different endpoint (e.g., an on-premises or partner-hosted Loqate instance):

macOS / Linux:

# Environment variables
export LOQATE_VERIFY_URL=https://custom-verify.example.com/v1/batch
export LOQATE_VERIFY_KEY=your-custom-key

# Or use flags (override env vars)
lqt verify -a "..." --verify-url https://custom-verify.example.com/v1/batch --verify-key your-custom-key

Windows (PowerShell):

$env:LOQATE_VERIFY_URL="https://custom-verify.example.com/v1/batch"
$env:LOQATE_VERIFY_KEY="your-custom-key"

Resolution order: flag > environment variable > default Loqate endpoint

When --verify-key is set, the standard --key / LOQATE_API_KEY is not required for address-only verification. If you also verify email (-e) or phone (-p), the standard key is still needed for those.

These flags only affect address verification. Email and phone always use the standard Loqate endpoints.

In MCP mode, clients can pass verify_url and verify_key per-request in verify_address and verify_contact tool inputs.
