## 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 fastx402-solana-transaction-status-a520f7c0
```

Example prompt: Can you check whether Solana transaction 4WgK9w95nm6YFXD3q9uqg8HT7mpcjxmZSWdzGUuses1Dz26LXTF7zzxwWhaTzqViqsyQn24V7qd2SF4yiWpSDhfx has been finalized yet?

## When to prefer this

Use this endpoint when you need a quick, no-account, pay-per-call lookup of a Solana transaction's status by its signature — ideal for AI agents that need to verify on-chain payment or action confirmation without setting up Solana RPC infrastructure or managing API keys.

## Known failure modes

- Invalid or malformed base58 signature returns an error response
- Transaction not yet indexed may return not-found or pending status
- Network timeouts from Solana RPC may cause delayed responses
- Very recent transactions may not be visible yet on the RPC node

## How this service works

200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

## Output

Returns a JSON object containing the transaction signature, its current status (e.g. 'success'), confirmation_status (e.g. 'finalized', 'confirmed', 'processed'), the slot it was included in, any error (null if successful), and current confirmations count.
