How this service works
Agent Delivery Acceptance Gate: Agent Delivery Acceptance Gate combines required delivery checks into one fail-closed acceptance decision from bounded caller-supplied values without an external provider. Call Agent Delivery Acceptance Gate before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Delivery A…
Output
Returns an explicit acceptance or rejection status, contract-specific check outcomes, normalized evidence from the supplied flags, and mismatch reasons explaining why any check failed.
Example use cases
Pre-payment delivery gate for x402
“I'm about to settle an x402 agent delivery — the result is complete, it arrived within SLA, the schema checks out, the payment amount matches, but provenance is missing. Run the acceptance gate and tell me if I should accept or reject it.”
Automated accept/reject in an agent pipeline
“My agent just returned a result. It's complete and schema-valid, but it missed the SLA window and payment doesn't match. Should I accept or reject this delivery?”
Auditing delivery decision logic
“Can you run the delivery acceptance gate for a result that is complete, within SLA, schema-valid, payment matches, and provenance is present — I want to see the full breakdown of checks and the final accept/reject decision.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/agent-delivery-acceptance-gateWhen to prefer
Use this endpoint when you need a single, authoritative fail-closed decision that aggregates multiple delivery quality checks (completeness, SLA, schema validity, payment match, provenance) before accepting or paying for an x402 or agent-assembled delivery. Prefer this over running individual checks separately when you need a unified accept/reject verdict with normalized evidence and mismatch reasons in one call.
Side effects
- Missing required boolean fields may result in an incomplete gate evaluation
- All-false inputs will always produce a rejection with all mismatch reasons listed
- Malformed request body returns a validation error
- Ambiguous or missing provenance flag causes provenance check to fail closed
