Revettr tools (3)

write = sends, deletes, buys or posts
  • export_audit_bundleFree

    Export a JWS-signed audit-trail bundle of scoring decisions for a wallet. MCP equivalent of GET /v1/audit/export. Compliance artifact for EU AI Act Article 12 logging / NYDFS certification / debanking-defense. Because audit data covers arbitrary wallets, this tool is operator-gated: pass the operator's ``admin_token`` (checked against ``REVETTR_ADMIN_TOKEN``). Disabled when that env var is unset. Note: ``admin_token`` travels in the MCP request payload, so operators should treat MCP transcripts/logs as sensitive. Verify the returned ``bundle_jws`` against /.well-known/jwks.json; the schema is in docs/audit-trail-export.md.

  • score_counterpartyFree

    Score a counterparty before sending money. Returns risk score 0-100. Accepts EVM wallets (0x...), Stellar wallets (G...), domains, IPs, and company names.

  • verify_issuerFree

    Get an advisory risk verdict for a validated MCP issuer (iss). Attach this at your MCP `iss` validation step: identity is your job, this adds risk. Returns the same signed RiskCheckResult as POST /v1/iss-verdict. Advisory and non-blocking — you decide based on the tier.

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

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.

Score Tiers

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:

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")
