How this service works
Generates a cryptographic attestation report verifying an autonomous AI agent wallet, x402 EIP-3009 payment capability, counterparty reputation score, and zero-drainer history on Base.
Output
A cryptographic attestation report containing: verification of the wallet's x402 EIP-3009 payment capability, a counterparty reputation score, confirmation of zero-drainer history on Base, and optionally domain-specific service verification — all signed as a tamper-evident report.
Example use cases
Screening agent wallet before payment
“I'm about to receive an x402 micropayment from agent wallet 0x4f2eB3c...a901 — can you run a CanaryGuard attestation on it to check its reputation score and make sure it has no drainer history on Base?”
Verifying x402 capability for a service domain
“Before I allow api.myservice.xyz to interact with our payment rails, can you get a cryptographic attestation confirming that wallet 0x9aF3d...77cc supports EIP-3009 payments and is cleared on Base?”
Onboarding check for new AI agent counterparty
“We're onboarding a new autonomous agent at 0x1B2C3D...4E5F — run a CanaryGuard attestation report on it so I can see its counterparty reputation score and zero-drainer status before we give it access.”
Technical details
Endpoint
GEThttps://canaryguard-402.onrender.com/v1/verify/agent-attestation?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographic attestation of an AI agent or merchant wallet's legitimacy before engaging in x402 EIP-3009 payments on Base — especially when counterparty reputation and drainer-free history are required trust signals. Prefer it over generic ENS lookups or on-chain balance checks when you need a structured, multi-dimensional trust report covering payment capability, reputation score, and safety history in a single call.
Side effects
- Invalid or malformed wallet address returns a 400 error
- Wallet not found on Base returns an unverifiable status
- Service domain does not match any known x402 provider
- Rate limiting or payment failure returns a 402 or 429 response
- Transient Base RPC outage may cause lookup failures
