## How to call it through Zero

```sh
zero fetch --capability solana-transaction-explainer-01e95dcb
```

Example prompt: Can you explain what happened with my Solana transaction — the signature is 5KtPn1LGuxhFKLRFdMmANPeF1zRJJHLoNNpqMYAhE4a8CnBpBqR1VZpXwsKhJ7gTPMrJNuJ3P5YVRwXDoSvGMrR? It failed and I need to know why and how to fix it.

## When to prefer this

Use this endpoint when you need a human-readable explanation of a specific Solana transaction — especially failed swaps, program errors, or suspicious activity — and want actionable fix suggestions without setting up an account or API key. Ideal for pay-per-call, low-volume agent workflows that need cheap on-demand transaction debugging.

## Known failure modes

- Invalid or malformed transaction signature returns an error response
- Transaction not yet finalized or not found on-chain may return empty or error result
- Network timeout or RPC unavailability causes request failure
- Payment failure via x402 (insufficient USDC balance) blocks the request

## How this service works

## Output

Returns a JSON object with the transaction status (e.g. 'failed' or 'success'), a plain-English explanation of what happened, the original error text if any, a suggested fix, the list of programs invoked, and the original signature.
