## 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 explorer-gateway-api-solana-transaction-lookup-9844681a -d '<json body>'
```

Example prompt: Can you look up the details of this Solana transaction — txId 5v3Xk9...abc — and tell me if it's confirmed and what the fee and amounts were?

## When to prefer this

Use this endpoint when you need to look up a Solana transaction by ID and want a paid, gateway-backed explorer API with reliable uptime from Blockchain.info. Prefer this over free public explorers when reliability, programmatic access, and multi-chain consistency matter. Best suited for agents that need to verify SOL payment confirmations, audit DeFi activity, or debug transaction failures on Solana.

## Known failure modes

- Invalid or malformed txId returns an error or empty result
- Transaction not yet indexed returns no data or pending status
- Incorrect network value (not 'SOL') may return an error or wrong-chain data
- Rate limiting or payment failure (402) if x402 payment is not processed
- Network timeouts if Solana RPC backend is slow or unavailable
