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-webhook-delivery-service-bdc92ead -d '<json body>'
```

Example prompt: Deliver my JSON payload to the DDG webhook service using x402 USDC micropayment — the body is a POST with JSON content type containing my order data, and I expect an ok:true confirmation back.

## When to prefer this

Choose this endpoint when you need to deliver bounded artifacts or trigger agent tasks via a machine-payable webhook that accepts x402 multi-chain USDC micropayments. Prefer this over raw provider API access when you want DDG to handle the underlying execution and simply need a confirmed delivery result. Best suited for AI agents that can autonomously settle $0.01 USDC micropayments via x402 protocol.

## Known failure modes

- Payment not settled or x402 payment header missing — returns 402 Payment Required
- Invalid or missing required fields (input.type, input.method, input.bodyType, input.body, output.type, output.example) — returns 400 Bad Request
- Unsupported HTTP method in input.method (not POST/PUT/PATCH) — returns validation error
- Provider environment not configured — service may be unavailable despite being listed
- Network timeout or webhook relay failure — ok:false or no response

## 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 with a boolean 'ok' field (e.g. {ok: true}) confirming successful webhook delivery of the submitted payload.
