## 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 47620-solana-transaction-signatures-lookup-44de1043
```

Example prompt: Pull the last 50 transaction signatures for the Solana address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU so I can see recent activity, which slots they landed in, their block times, and whether any failed.

## When to prefer this

Use this endpoint when you need a chronological list of recent transaction signatures for a specific Solana address, especially for activity monitoring, auditing, or feeding signature IDs into downstream lookups. Prefer this over a full transaction detail endpoint when you only need lightweight metadata (slot, time, error flag) rather than full instruction data, or when you need to batch-check activity across a time window quickly.

## Known failure modes

- Invalid Solana address format returns an error response
- Address with no transaction history returns an empty list
- limit parameter exceeding 1000 may be rejected or capped
- Network congestion may cause slight delays in the most recent signatures appearing
- Payment of 0.005 USDC not included or invalid causes request rejection

## 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 transaction signature objects for the given Solana address, each containing the base58 signature string, the slot it was confirmed in, the Unix blockTime timestamp, and a boolean/flag indicating whether the transaction resulted in an error. Up to 1000 records can be returned per call via the ?limit= query parameter.
