What does a score mean?

Scores 80-100 indicate low risk, 60-79 medium risk, 30-59 high risk, and 0-29 critical risk where you should not transact.

How does the payment system work?

The client automatically handles x402 micropayment flow on Base, charging $0.01 USDC per request.

Can I block payments to risky counterparties automatically?

Yes, using SafeX402Client you can configure a minimum acceptable score to block or warn on payments.

Are sanctions lists checked?

Yes, the server screens against OFAC, EU, and UN consolidated sanctions lists.

We ran the install command below but it didn't respond within our test window — this can mean a slow first-time install rather than a real problem.

This is an experimental automated check and can have false negatives — missing environment variables, a slow cold install, etc. It doesn’t necessarily mean something’s wrong. Last checked 1mo ago.

Overview

This server provides counterparty risk scoring by analyzing domain intelligence, IP reputation, on-chain wallet activity, and sanctions lists. It is designed for AI agents conducting transactions via the x402 micropayment protocol on the Base blockchain. Use it to decide whether to transact with a given counterparty by providing any combination of domain, IP, wallet address, and company name. The score ranges from 0 (critical risk) to 100 (low risk), with detailed flags explaining risk factors.

Use cases

Score a counterparty's trustworthiness before sending funds

Screen wallets, domains, IPs, and companies for risk indicators

Integrate with AI agent commerce workflows on Base using x402 payments

Block payments automatically if counterparty risk is too high

Evaluate counterparties before creating jobs on Agent Commerce Protocol

Key features

Scores multiple signal groups: domain, IP, wallet, sanctions

Returns numeric score, tier, confidence, and detailed risk flags

Supports partial input data for flexible scoring

Automatic x402 micropayment handling for API calls

SafeX402Client blocks or warns on risky counterparties before payment

Capabilities & Tool Schemas

Inspect callable tools, capabilities, and parameters exposed to AI agents by Revettr Python.

Documentation Overview

Revettr

Counterparty risk scoring for agentic commerce. One API call answers: "Should this agent send money to this counterparty?"

Revettr scores counterparties by analyzing domain intelligence, IP reputation, on-chain wallet history, and sanctions lists. It's designed for AI agents transacting via x402 on Base.

Install

Terminal

pip install revettr

Quick Start

server.ts

from revettr import Revettr

client = Revettr()

# Score a counterparty — send whatever data you have
score = client.score(
    domain="uniswap.org",
    ip="104.18.28.72",
    wallet_address="0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
)

print(f"Score: {score.score}/100 ({score.tier})")
print(f"Confidence: {score.confidence}")
print(f"Flags: {score.flags}")

if score.tier == "critical":
    print("DO NOT TRANSACT")

What Gets Scored

Send any combination of inputs. More data = higher confidence.

Input	Signal Group	What It Checks
`domain`	Domain Intelligence	WHOIS age, DNS config (MX, SPF, DMARC), SSL certificate
`ip`	IP Intelligence	Geolocation, VPN/proxy/Tor detection, datacenter vs residential
`wallet_address`	Wallet Analysis	Transaction count, wallet age, counterparty diversity, on-chain behavior
`company_name`	Sanctions Screening	OFAC SDN, EU consolidated, UN consolidated sanctions lists

Score Tiers

Score	Tier	Meaning
80-100	`low`	Counterparty appears legitimate
60-79	`medium`	Some signals warrant caution
30-59	`high`	Multiple risk indicators present
0-29	`critical`	Strong risk signals — do not transact

A score of 0 means a hard match (e.g., exact sanctions hit). This overrides all other signals.

Risk Flags

Flags tell you exactly what triggered a score reduction. They are grouped by signal category:

Category	Examples	What It Covers
Domain	`domain_age_under_`, `no_mx_records`, `ssl_`	Domain age, DNS hygiene, SSL validity
IP	`tor_exit_node`, `known_vpn`, `high_risk_country_*`	Anonymization, geolocation risk
Wallet	`wallet_never_transacted`, `wallet_age_under_*`	On-chain history, activity patterns
Sanctions	`sanctions_exact_match`, `sanctions_high_confidence_match`	OFAC/EU/UN sanctions screening

The full set of flags and their descriptions are returned in the API response. Flag names are stable and machine-readable.

Usage Examples

Wallet only (minimal)

python

score = client.score(wallet_address="0xabc...")

Domain + IP (web service check)

python

score = client.score(domain="some-api.xyz", ip="185.220.101.42")

Full check

python

score = client.score(
    domain="merchant.com",
    ip="104.18.28.72",
    wallet_address="0xabc...",
    company_name="Merchant LLC",
)

With x402 auto-payment

The client handles x402 payment automatically. You need a funded wallet:

server.ts

from revettr import Revettr

client = Revettr(
    wallet_private_key="0xYOUR_PRIVATE_KEY",  # Wallet that pays for the API call
)

# Client automatically handles the 402 → payment → retry flow
score = client.score(wallet_address="0xabc...")

Security: Never hardcode private keys. Use environment variables or a secrets manager in production.

With Virtuals Protocol (ACP)

Score seller agents before creating jobs on the Agent Commerce Protocol:

server.ts

from revettr import Revettr

client = Revettr()
result = client.score(wallet_address=seller_wallet)
if result.score >= 60:
    # Safe to create ACP job
    job_id = chosen_offering.initiate_job(
        service_requirement={"task": "Analyze Q1 sales data"},
        evaluator_address=evaluator_address,
    )

See examples/virtuals_acp_safe_buyer.py for the full buyer agent flow.

Safe Agent Payments

Drop-in replacement for x402 payments that automatically checks counterparty risk before sending money. If the counterparty scores below your threshold, the payment is blocked.

server.ts

from revettr import SafeX402Client, PaymentBlocked

async with SafeX402Client(
    wallet_private_key="0x...",
    min_score=60,    # Block "high" and "critical" risk
    on_fail="block", # Raise PaymentBlocked (default)
) as http:
    try:
        # Automatically scores the counterparty before paying
        response = await http.post("https://some-api.com/endpoint", json=data)
    except PaymentBlocked as e:
        print(f"Blocked: {e.url} scored {e.score}/100")

`on_fail`	Behavior
`"block"` (default)	Raise `PaymentBlocked` exception
`"warn"`	Log warning, proceed with payment
`"log"`	Silently log, proceed with payment
