Technical details
Endpoint
POSThttps://x402trustlayer.xyz/api/attestation/verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify whether a specific attestation is valid and permitted within the x402 Trust Layer ecosystem — particularly before executing gated actions, fulfilling mandates, or confirming certified-seller or identity claims. Prefer this over generic auth checks when you are operating within the x402 trust infrastructure and need a formal attestation record with an ID.
Side effects
- Invalid or missing `type` field returns a validation error
- Unsupported HTTP method (e.g. POST or PUT) rejected — only GET, HEAD, DELETE allowed
- Attestation not found returns allowed: false or error response
- Payment not received results in 402 response before processing
- Malformed request body returns 400-level error
