## 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-address-transactions-2e184627 -d '<json body>'
```

Example prompt: Pull the last 25 transactions for Solana address 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM on the SOL network.

## When to prefer this

Use this endpoint when you need to fetch on-chain transaction history for a specific Solana address with cursor-based pagination support. It is ideal for auditing wallet activity, monitoring smart contract interactions, or building transaction timelines for SOL accounts. Prefer this over generic blockchain APIs when you need reliable, paginated Solana transaction data from a well-known explorer provider (Blockchain.com).

## Known failure modes

- Invalid or malformed Solana address returns an error response
- Network value not matching 'SOL' may return no results or an error
- Limit outside the 1–50 range is rejected
- Invalid 'before' cursor signature yields an error or empty result
- Payment failure (x402) blocks the request if USDC funds are insufficient
- Rate limiting if too many requests are made in quick succession

## How this service works

## Output

A JSON array of transaction records for the specified Solana address, including transaction signatures and metadata, paginated up to the requested limit (1–50). Supports cursor-based pagination via the 'before' signature field to retrieve older transactions.
