How this service works
68 paid x402 trust infrastructure APIs: guard, semantic escrow, mandate diff, certified seller network, KYM, mandates, compliance, disputes, and orchestration.
Output
Returns a JSON object with ok (boolean), mode ('semantic'), status, allowed flag, a human-readable summary explaining the score vs threshold, a decision ('release-to-merchant' or hold), individual semanticScore, schemaScore, qualityScore, and escrowStatus ('released' or 'held').
Example use cases
Example prompt
“Settle the quality escrow for the API call I just made — run the semantic and schema scoring and release the payment to the merchant if the combined quality score hits 72 or above.”
Technical details
Endpoint
POSThttps://x402trustlayer.xyz/api/quality-escrow/semantic-settle?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically settle a quality-gated escrow payment after an x402 API interaction — specifically when you want combined semantic + schema scoring to govern whether the merchant receives USDC. Prefer this over a simple mandate-verify endpoint when quality of the API response (not just payment validity) must be confirmed before funds are released.
Side effects
- Missing required 'input' field returns validation error
- Invalid HTTP method (e.g. POST/PUT) rejected by enum constraint — only GET, HEAD, DELETE allowed
- Scores below threshold result in escrow held, not released
- Malformed request body causes 400 error
- Payment not found or already settled may return escrow conflict error
- Upstream scoring service unavailability may cause timeout
