Example use cases
Example prompt
“Before I let my agent auto-pay this endpoint, can you check the reputation of the payTo wallet 0xAbC123... on domain api.example.com — tell me if it has solid call history, whether the price looks sane, and whether I should allow, warn, or block payments to it?”
Technical details
Endpoint
POSThttps://x402-endpoint-risk-corpus.mtree.workers.dev/v1/x402/payee_reputationWhen to prefer
Use this endpoint when an AI agent needs to vet an x402 payee before authorizing an autonomous or semi-autonomous payment — especially when the payee is newly encountered, high-value, or unknown. Prefer this over generic OFAC/fraud checks when the specific concern is x402 protocol safety: price drain, replay risk, and call history within the Bazaar-derived corpus.
Side effects
- Unknown wallet or domain with no observed history returns minimal data or warn-by-default policy
- Malformed wallet address or URL causes 400 bad request
- Insufficient corpus data for new endpoints may yield low-confidence scores
- Payment not received or invalid x402 payment header returns 402 or 401
- Rate limiting or overload returns 429 or 503
