Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/base/usdc-receiptWhen to prefer
Use this endpoint when you need a structured, machine-readable receipt and risk assessment for a specific USDC transaction on Base (chain ID 8453). Prefer this over generic block explorers when you need a normalized risk score, flags, and provenance in a single API call suitable for agent workflows.
Side effects
- Invalid or malformed transaction hash (not matching ^0x[a-fA-F0-9]{64}$) returns an error
- Transaction hash not found on Base network returns not-found error
- Non-USDC transaction hash may return unexpected or empty activity data
- Network timeout or upstream RPC failure may cause delayed or failed response
- Payment of 0.003 USDC not fulfilled results in 402 Payment Required
