Revettr

Glama MCP server

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

pip install revettr

Quick Start

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)

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

Domain + IP (web service check)

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

Full check

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:

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:

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.

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
