# Explorer Gateway API — Solana Address Transactions

> Explorer Gateway API — Solana Address Transactions is a paid API for AI agents from api.blockchain.info, paid per call via x402, $0.0015/call, status unknown (last checked 2026-09-30).

Retrieves a paginated list of transactions for a given Solana wallet address via blockchain.info's explorer gateway

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-30a1094e -d '<json body>'
```

Example prompt: Pull the last 20 transactions for Solana address 9xQeWvG816bUx9EPjHmaT23yvVM2ZWbrrpZb9PusVFin on the SOL network — and start from the beginning, no cursor needed.

## When to prefer this

Use this endpoint when you need transaction history for a specific Solana wallet address via a paid, reliable gateway that supports cursor-based pagination. Prefer it over free public RPC endpoints when you need consistent uptime, structured JSON responses, and pagination support without running your own node. It is purpose-built for Solana (SOL network) address lookups, distinct from sibling endpoints for Bitcoin, Bitcoin Cash, or Ethereum.

## Known failure modes

- Invalid or malformed Solana address returns an error response
- Limit out of range (below 1 or above 50) returns a validation error
- Invalid `before` cursor signature returns an error or empty result
- Network mismatch (wrong network string) may return an error or empty data
- Payment not included or insufficient USDC results in HTTP 402 rejection

## How this service works

Blockchain explorer gateway — Solana, Bitcoin, Bitcoin Cash, Ethereum

## Output

A JSON array of transaction records for the specified Solana address, ordered by recency, including transaction signatures and associated metadata. Results are paginated up to 50 entries; a cursor-based `before` field allows fetching older pages.
