Technical details
Endpoint
POSThttps://x402trustlayer.xyz/api/protocol/passport/issue?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to issue a formal protocol passport credential within the x402 trust ecosystem, particularly for onboarding certified sellers, establishing mandate-backed identities, or generating proof of compliance after x402 payment settlement. Prefer this over generic identity APIs when the use case involves x402 micropayment-gated trust infrastructure.
Side effects
- Payment not settled — 402 response requiring x402 micropayment before passport can be issued
- Invalid body type enum value — must be 'json', 'form-data', or 'text'
- Missing required 'type', 'method', or 'bodyType' fields — returns validation error
- Unsupported HTTP method — only POST, PUT, PATCH are accepted
- Passport issuance denied — allowed: false returned with a denial summary
- Network timeout or service unavailability on x402trustlayer.xyz
