# Agent Delivery Acceptance Gate

> Agent Delivery Acceptance Gate is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Combines multiple delivery validation checks into a single fail-closed accept/reject decision for x402 or agent-delivered results based on caller-supplied boolean checks.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-delivery-acceptance-gate-c26e24c0 -d '<json body>'
```

Example prompt: Before I pay for this agent delivery, run it through the acceptance gate — the result is complete, within SLA, schema-valid, payment matches, and provenance is present — and tell me whether to accept or reject it.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
