# DDG Agent-Checkout Conformance Audit

> DDG Agent-Checkout Conformance Audit is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Audits an agent's HTTP request and response pair for conformance with agent-checkout and x402 payment-rail standards, returning a pass/fail result.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 ddg-agent-checkout-conformance-audit-045a7f47 -d '<json body>'
```

Example prompt: Run a conformance audit on this agent checkout call — it's an HTTP POST with a JSON body containing our payment payload, and the expected output type is JSON with an example of {ok: true}. Make sure the request and response pair meet DDG's agent-checkout standards.

## When to prefer this

Use this endpoint when you need to verify that an agent's HTTP request and response pair correctly implements the DDG agent-checkout and x402 payment-rail specification before going live or when debugging integration failures. It is specifically suited for teams building machine-payable services on DDG's platform rather than general HTTP linting or generic API validation.

## Known failure modes

- Missing required fields (input or output) returns a validation error
- Unsupported HTTP method (e.g. GET instead of POST/PUT/PATCH) causes rejection
- Invalid bodyType enum value causes schema validation failure
- Malformed JSON body causes parse error
- Payment not settled causes 402 response before audit runs

## How this service works

Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.

## Output

A JSON object with an 'ok' boolean field indicating whether the submitted HTTP request and response pair conforms to DDG agent-checkout standards. Additional conformance detail may be included in the response body.
