How this service works
Machine-payable service intelligence for discovering, verifying, and monitoring identity, risk, authorization, execution-preflight, and evidence APIs before autonomous agents spend.
Output
Returns a JSON object containing the product identifier ('bcs-wallet-risk-bundle'), upstream service name ('blockchainsecurity-atlantis'), response metadata including request ID, credit cost and credit remaining, and a nested upstream_response with a data object containing the wallet risk assessment and meta fields.
Example use cases
DeFi counterparty risk check
“Before my agent pays this wallet on Base, can you fetch the risk bundle for address 0xDEADBEEF...cafe on the base blockchain so I can see if it's flagged for anything suspicious?”
Token contract security audit
“I need a wallet risk bundle for address 0x1234abcd... on Ethereum, and also check contracts 0xAAA...,0xBBB... — I want to know if any of these are associated with known exploits.”
Pre-purchase agent eligibility check
“My agent is about to buy a dataset through x402 — can you first run the wallet risk preflight for address 0x9876...fedc on the polygon blockchain to make sure the buyer wallet clears the risk policy?”
Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/bcs/wallet-risk-bundleWhen to prefer
Choose this endpoint when an AI agent needs to perform a blockchain wallet risk assessment as part of an x402-gated purchase flow, particularly when buyer eligibility governance and wallet security scoring need to happen together before committing funds. Prefer it over direct blockchain security APIs when you are operating within the x402 payment ecosystem and need the preflight governance layer included.
Side effects
- Missing required query params (blockchain or address) returns a 400 bad request
- Invalid address format (fails regex ^[A-Za-z0-9:_-]{3,128}$) causes validation error
- Unknown or unsupported blockchain identifier returns an error from upstream
- x402 payment not included or insufficient funds causes 402 Payment Required
- Upstream blockchainsecurity-atlantis service unavailable returns 502 or timeout
- Rate limiting or credit exhaustion on upstream returns credit_remaining: 0 signal
