## 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 solprobe-trade-execute-f53fb07b -d '<json body>'
```

Example prompt: Submit and execute this pre-signed Solana transaction for job abc-123 — here's the base64-encoded signed transaction: 'AQAAAA...base64string...' — I need the confirmed on-chain tx signature back.

## When to prefer this

Use this endpoint when you have already prepared and signed a Solana transaction (e.g. from a prior quote or job creation step) and need to broadcast and confirm it on-chain. This is specifically for the execution/submission step, not for querying token data or generating trade quotes. Prefer this when you need a confirmed tx signature as proof of execution.

## Known failure modes

- Invalid or expired job_id returns error or unprocessed status
- Malformed or invalid base64 signed transaction causes rejection
- Transaction already submitted (non-idempotent) may return duplicate or conflict error
- Solana network congestion or RPC failure may delay or fail confirmation
- Insufficient USDC payment via x402 protocol results in 402 Payment Required
- Transaction simulation failure or slippage exceeded causes on-chain failure

## How this service works
