Technical details
Endpoint
POSThttps://x402trustlayer.xyz/api/spend-governor/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to pre-check whether a spending action is permissible under the active x402 mandate or governance policy before committing to a paid operation. Prefer this over general compliance checks when working within the x402 micropayment ecosystem and needing a lightweight allow/deny gate for HTTP-level spend decisions.
Side effects
- Missing required 'input' field returns validation error
- Unsupported HTTP method (e.g. POST, PUT) fails schema validation since only GET, HEAD, DELETE are allowed
- Payment not settled results in 402 response requiring x402 payment flow
- Malformed input object with extra properties rejected due to additionalProperties: false
- Network timeout or service unavailability returns 5xx error
- Spend limit exceeded returns allowed: false with explanatory summary
