## 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 solana-address-transaction-signature-history-9441235c
```

Example prompt: Show me the last 50 transaction signatures for Solana address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU, including whether any had errors.

## When to prefer this

Use this endpoint when you need a live, up-to-date list of recent transaction signatures for a Solana address for activity monitoring, auditing, or pre-payment due diligence. Prefer it over full transaction detail endpoints when you only need signatures, slots, block times, and error flags — it is faster and cheaper than fetching full transaction data.

## Known failure modes

- Invalid Solana address format returns an error
- Limit parameter exceeding 1000 may be capped or rejected
- Address with no transaction history returns empty list
- Network or RPC unavailability causes timeout or 5xx error
- Malformed request returns 400 bad request

## How this service works

Latest transaction signatures for an address (signature, slot, blockTime, error flag). ?limit= up to 1000. Live, for activity tracking.

## Output

Returns a list of up to 1000 transaction signature records for the specified Solana address, each containing the transaction signature string, slot number, blockTime (Unix timestamp), and a boolean error flag indicating whether the transaction failed.
