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-llm-audit-bill-6d484130 -d '<json body>'
```

Example prompt: Submit this LLM request and response pair to DDG's audit-bill endpoint for billing — the request was a POST with JSON body containing the prompt I sent, and the response confirmed success.

## When to prefer this

Choose this endpoint when you need per-call LLM usage auditing with built-in micropayment billing via the x402 protocol, particularly in agent pipelines where each inference must be individually tracked and billed at $0.01 USDC per call. It is best suited for automated agent workflows that require an auditable billing trail for LLM API usage rather than batch or subscription billing.

## Known failure modes

- Missing required 'input' or 'output' fields returns a validation error
- Invalid HTTP method (not POST/PUT/PATCH) in the input body causes rejection
- Payment failure via x402 rail results in 402 Payment Required response
- Malformed JSON body type mismatch causes schema validation failure
- Network timeout if the x402 payment settlement takes too long

## 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

Returns a JSON object confirming the audit-bill record was created, with an 'ok: true' field on success indicating the request has been logged and the micropayment processed.
