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-payable-ai-skill-port-b3e92079 -d '<json body>'
```

Example prompt: Call the DDG agent skill port with my POST request body as JSON and pay the $0.02 USDC fee automatically via x402 so I get back the bounded result artifact.

## When to prefer this

Choose this endpoint when your AI agent needs to invoke DDG-specific bounded AI skills or artifacts on a pure pay-per-call basis with no subscription required, using the x402 USDC micropayment protocol for automatic settlement. Prefer it over subscription APIs when you want zero commitment per-task billing at $0.02 USDC, and over generic LLM APIs when you specifically want DDG-packaged, bounded deliverables rather than raw model access.

## Known failure modes

- Payment settlement failure — x402 USDC payment not confirmed, request rejected with 402
- Malformed body — missing required 'input' or 'output' fields returns validation error
- Unsupported HTTP method in inner input — only POST/PUT/PATCH accepted
- Provider environment not live for MPP/Stripe/Tempo rails — those payment methods silently unavailable
- Insufficient USDC balance — agent wallet cannot cover $0.02 fee, transaction blocked
- Network timeout — crypto settlement confirmation takes too long, request times out

## 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 response with an 'ok' boolean indicating success, plus any bounded artifact or skill result data produced by the invoked DDG service. The exact shape of the result payload depends on the specific skill invoked via the body.
