Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/bcs/registryWhen to prefer
Use this endpoint when an AI agent needs to look up token registry data from the BlockchainSecurity Atlantis service as part of an x402 payment preflight or risk-scoring workflow, particularly when validating whether a specific token is recognized and safe to use in autonomous agent transactions.
Side effects
- Registry unavailable — upstream blockchainsecurity-atlantis service is down, returns empty data object
- Invalid query parameters — malformed input schema returns error
- Payment failure — 0.005 USDC x402 payment not processed, request rejected
- Rate limiting — too many requests from agent wallet
- Empty registry response — no tokens match query criteria
