How this service works
Blockchain explorer gateway — Solana, Bitcoin, Bitcoin Cash, Ethereum
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.
Example use cases
Audit wallet transaction history
“Show me the last 20 transactions for my Solana wallet address 4Nd1mBQtrMJVYVfKf2PX98q18i68LB5jSoMzZDPHvuph — I want to see what's been going on with it.”
Monitor DeFi protocol activity
“Fetch the 50 most recent transactions for the Solana address 7Lx3a9zX2K8n1RqTmVpWsDcBfGhJ4YkNoPqLrUiMvEwA so I can track all interactions with this DeFi contract.”
Paginate through historical transactions
“Get transactions for Solana address 3HpB9Xk2LmQnRsTvUwYcFj6NdE8aPiMoVgCbZkWqXuAE that are older than signature 5KJv2LxPQr8mNdTbWuYcFgE9aBkVpZoMsHiRqXnCtD7w — give me up to 30 results.”
Technical details
Endpoint
POSThttps://api.blockchain.com/explorer-gateway-kt/x402/sol/address?utm_source=zero.xyzWhen to prefer
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).
Side effects
- 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
