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-services-unichain-transaction-endpoint-4a131b3c -d '<json body>'
```

Example prompt: Submit a JSON POST request to DDG's Unichain agent service — the body should include my data payload, and pay the $0.01 USDC fee via x402.

## When to prefer this

Choose this endpoint when your agent needs to execute a paid service request specifically on the Unichain network via DDG's x402 micropayment infrastructure at $0.01 USDC per call. Prefer this over generic blockchain RPC endpoints when you need a structured, agent-friendly HTTP transaction wrapper with built-in micropayment handling.

## Known failure modes

- Insufficient USDC balance to cover $0.01 fee — payment rejected
- Invalid or missing required fields (input.type, input.method, input.bodyType, input.body, output.type, output.example) — 400 Bad Request
- Unichain network unavailability or congestion — transaction timeout
- Unsupported HTTP method in input.method (only POST, PUT, PATCH allowed) — validation error
- Unsupported bodyType value — enum validation failure
- x402 payment protocol negotiation failure — 402 Payment Required with no valid resolution

## 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 indicating success or failure of the transaction, with an 'ok' boolean and any additional response data from the DDG service endpoint on Unichain.
