## 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-c3186082 -d '<json body>'
```

Example prompt: Can you look up Solana transaction 5xK9...abc on the blockchain explorer and tell me whether it was confirmed, how much SOL was transferred, and who the sender and receiver were?

## When to prefer this

Use this endpoint when you need authoritative, on-chain Solana transaction data from a well-known blockchain explorer (blockchain.com) without running your own node. Prefer it over raw RPC calls when you want a structured JSON response with no infrastructure setup, and over generic multi-chain explorers when Solana-specific detail is required.

## Known failure modes

- Invalid or malformed txId returns an error or empty result
- Transaction not yet indexed returns a not-found response
- Incorrect network parameter causes mismatch or error
- Network congestion may cause delayed indexing of recent transactions
- Payment failure (x402) if USDC balance is insufficient
