How this service works
Independent risk-signal layer for x402 agentic commerce — endpoint evidence (decoy / zombie / price-trap / never-paid) before an agent authorizes payment.
Output
Returns one verdict object per submitted URL (including ok, warnings, risk_score, recommended_action, settlement count and recency metadata) plus a top-level batch summary covering the full set of up to 50 URLs.
Example use cases
Example prompt
“Before I pay any of these 12 x402 endpoints, run a preflight batch check on all of them and tell me which ones look risky, which are safe, and what the settlement history looks like for each.”
Technical details
Endpoint
POSThttps://x402station.io/api/v1/preflight-batchWhen to prefer
Use this endpoint when an agent needs to screen multiple x402 endpoints in a single call before committing funds. It is more efficient than calling the single-URL preflight endpoint repeatedly, and cost-effective at a flat $0.025 for up to 50 URLs. Prefer it when orchestrating multi-step agentic workflows that might fan out to several x402 services simultaneously.
Side effects
- More than 50 URLs submitted — batch size limit exceeded
- Malformed or non-x402 URLs in the input list
- Insufficient USDC balance to cover $0.025 fee
- Endpoint unreachable or x402 handshake fails for one or more URLs
- Network timeout on bulk evaluation
