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-avalanche-transaction-service-5368469d -d '<json body>'
```

Example prompt: Submit a JSON transaction body to the DDG Avalanche chain agent service — POST the payload with content type JSON and expect a success confirmation back.

## When to prefer this

Choose this endpoint when you need to submit a transaction or state-changing operation to the Avalanche blockchain through a micropayment-gated ($0.01 USDC) agent-accessible relay, particularly when operating within an x402-compatible agent payment framework and you need a simple HTTP-based interface rather than a direct RPC connection.

## Known failure modes

- Payment not included or insufficient — x402 payment required error
- Invalid HTTP method supplied — only POST, PUT, PATCH are accepted
- Malformed or missing required body fields — schema validation failure
- Avalanche network congestion or node unavailability — upstream timeout
- Invalid bodyType enum value — must be json, form-data, or text
- Missing required 'input' or 'output' fields in request body

## 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 an 'ok' boolean indicating whether the transaction was successfully submitted to the Avalanche chain, along with any additional response fields from the underlying service.
