Treg (OpenRouter for Tools)

OpenRouter, but for agent tools instead of models. Point an agent at one base URL with one token and it can do the job: 2,896 catalogued endpoints across 60 providers — SEO and backlinks, social and trends, people and company enrichment, ads, scraping — priced per call, from a cent, with no provider signup. Plus your own team's keys, skills and CLIs, callable by every teammate's agent without the credential ever leaving the server.

Ask for the task, not the tool. You do not need to know which vendor sells backlink data, or to hold an account with them. Search for what you want to do, read the price, call it.

Built for the Superdesign team, live at treg.to — anyone can self-host.

Why it exists

The tools an agent needs for real work sit behind subscriptions nobody buys for a single run — Semrush $139/mo, Moz $99/mo, Crunchbase $99/mo, Apollo $59/seat — behind signup walls, or behind no public API at all (invite-only, partner-only, app-review-only). treg carries those accounts and bills fractions of a cent per call.

Two kinds of tool, one token

• The catalog — external endpoints treg can serve on its own key, metered against your team's prepaid balance ($1.00 free on every new team). No account with the provider needed.
• Your own tools — anything a teammate registered: a paid API account, an OAuth connection, a vendor CLI, a SKILL.md. Your own key always wins over treg's, and those calls are never metered.

The vocabulary for the second half:

• tool = something the registry calls for you with the org's credential. Two kinds:
  • endpoint — an upstream base_url + credential bindings (each binding injects one secret into the request; a request can carry several, e.g. an OAuth bearer and a developer-token header).
  • CLI — a vendor binary (stripe, gh, vercel, ...) run with the credential injected.
• skill / bundle = a recipe (SKILL.md) + its secrets + its tool(s), registered together.

The one rule: the proxy relays, never models the upstream, and injects auth server-side — so it survives upstream API changes and callers never hold keys.

Part 1 · Using the registry

Visit treg.to (hosted on Render) — the dashboard, sign-in, and every URL below live there.

Quickstart

Same flow as the dashboard's Getting started guide:

# 1. install the CLI — also points it at the registry
curl -fsSL https://treg.to/install.sh | sh

# 2. sign in (GitHub default · --email for a one-time code · --token for agents/CI)
treg login

# 3. do something useful immediately — no key, nothing registered
treg catalog search "backlinks for a domain"     # find a tool by what it DOES
treg call tikhub.tiktok.user.profile --query uniqueId=tiktok
treg balance                                     # exactly what that cost

# (or `treg onboard` for the guided walkthrough)

Your token identifies you on every call (X-Treg-Token header) and is the same for all tools. Discover what your team has shared: treg tool ls · check credential health: treg health.

Or install it as a Claude Code plugin

/plugin marketplace add superdesigndev/treg
/plugin install treg@treg

Installs with no token and no configuration. The skill loads as treg:treg and, on its first run, walks your agent through the rest — the CLI, sign-in, then treg mcp install — so you end up with the command line and treg's tools. Other agents: npx skills add superdesigndev/treg -s treg (the -s matters — without it you also get this repo's internal dev skills). See docs/CLAUDE-PLUGIN.md. MiniMax Code / MiniMax Agent users: the same skill ships via the MiniMax Plugin Marketplace (docs/MINIMAX-PLUGIN.md).

Claude.ai connector

The Claude Connectors Directory surface is https://treg.to/mcp/v2/. It exposes only curated catalog endpoints and separates read calls from write calls so Claude receives accurate safety signals. The existing /mcp/ surface remains available for catalog endpoints, team-owned tools, and imported skills. See the MCP and OAuth architecture for the boundary and implementation, and the submission runbook for release gates.

Call a tool you don't have a key for

The catalog is grouped by what endpoints do: keyword and rank tracking, backlinks and authority, AI visibility, trending and discovery, publishing to socials, people and company enrichment, ads management and creative, measurement.

treg catalog                                    # every platform, busiest first
treg catalog search "find a work email"         # by the job, not the vendor
treg catalog get hunter.people.email.find       # params, PRICE, example response
treg call hunter.people.email.find --query domain=reddit.com --query full_name="Alexis Ohanian"

How a catalogued call is served — the credential ladder, in order:

1. your team registered its own tool for that provider → that tool, that key;
2. your team stored a secret for the provider → injected through a virtual tool;
3. neither → treg's own key, billed to the team's prepaid balance.

Your own credential always beats treg's, so connecting a key you already pay for makes those calls free of the balance rather than duplicating them. An endpoint treg has no published price for is refused, not served free — you are told to connect your own key instead. Where several providers serve one capability, treg catalog search shows them side by side with prices; choosing is yours — treg does not silently pick or fail over between providers for you. (When treg's own account for a provider is out it may serve the same endpoint through a treg-owned relay account, disclosed on the response; a team can opt out.) The exception you opt into: treg.<capability> routed endpoints, where treg picks the provider for you and names it.

treg balance          # credit left, calls in flight, recent spend
treg topup            # add funds, or set up automatic top-ups

Out of balance is an HTTP 402 carrying balance_micro, estimated_cost_micro and a topup_url, so an agent can act on it without reading prose.

Share & use your own tools

The zero-thought path — point treg at a project and it figures out what's shareable:

treg scan     # read-only preview: the keys, skills & CLIs upload would register
treg upload   # register them (encrypted server-side); idempotent, --replace to update

treg upload scans the .env (matching keys against ~80 known providers), every skill subdirectory, and installed catalog CLIs. Three kinds of things go into the registry — here's how to share and use each:

1. Endpoints (HTTP APIs)

Share — one upstream URL callable with a stored key, or bulk from a .env:

treg secret add STRIPE_KEY --value sk_live_123
treg add stripe --base-url https://api.stripe.com --secret STRIPE_KEY

treg upload env --select openai,stripe,resend     # or straight from the .env

Use — the agent-native way: build the real upstream request and prefix it with the proxy. treg resolves the tool by host, injects the credential, and relays everything else faithfully (your X-Treg-Token is stripped before the upstream sees it):

Real request:   GET https://api.intercom.io/conversations?per_page=5
Through treg:   GET https://treg.to/call/https://api.intercom.io/conversations?per_page=5
                    header:  X-Treg-Token: <your token>

Or the CLI shorthand — and treg calls for the audit log:

treg call intercom conversations --query per_page=5
treg call stripe v1/balance

2. CLIs

Share — automatic: treg upload detects installed catalog CLIs (stripe, gh, vercel, …) and registers them; a recipe-only catalog CLI skill (e.g. stripe-cli) auto-becomes runnable too.

Use — treg run executes the vendor CLI with the org's credential injected, so you never hold the key or log in:

treg run stripe -- get /v1/balance
treg run gh -- pr list
treg run --server agentmail-cli inboxes list   # runs on the registry server: the key never reaches you

--local (default) runs on your machine; --server runs on the registry and streams output back. For a whole session, treg shell start opens a subshell where every registered CLI injects automatically — just use stripe, gh, … normally; exit reverts. treg runs is the audit log.

3. Skills

Share — a skill is a whole capability (SKILL.md recipe + its secrets + its tool(s)), registered together so the whole team runs the same skill, maintained in one place:

treg upload skills --dir ~/.claude/skills --all   # register a folder of skills in one pass

Use — pull any shared skill into your agent; its API calls go through treg with your token, so the key stays on the server, never in the skill:

treg skill install seo-blog-writer      # writes into ./.claude/skills/  (--all for the library)

Manual registration — when the heuristics can't figure a tool out

# multi-credential tool (e.g. google-ads: OAuth bearer + a developer-token header)
treg tool add google-ads --base-url https://googleads.googleapis.com \
  --bind "secret=<oauth-id>,injector=oauth" \
  --bind "secret=<dev-id>,name=developer-token,format={secret}"

# one skill, step by step
treg skill init --dir ./my-skill          # drafts treg.json (guesses base_url, finds secrets)
treg skill add  --dir ./my-skill          # registers recipe + secrets + tool, atomically
