Paid AI-agent access to Blockchain.com Explorer API
Output
Returns a JSON response containing paginated transaction records associated with the queried Ethereum address, including details about individual on-chain activity such as transaction hashes, amounts, timestamps, and counterparty addresses.
Example use cases
Audit a wallet's on-chain history
“Can you fetch the full transaction history for Ethereum address 0x4Fbe8C6A5B2d... on the ETH network? I want the first page of 20 transactions so I can audit what's been going in and out.”
Monitor a DeFi protocol contract
“Look up the recent transactions for Ethereum address 0xC02aaA39b223... on ETH — give me the first 50 entries so I can see what interactions have happened with this contract lately.”
Verify a payment was received
“Check whether Ethereum address 0x7a250d5630B4... on the ETH network has received any transactions recently — pull page 1 with 20 results so I can confirm the payment went through.”
Technical details
Endpoint
POSThttps://api.blockchain.info/explorer-gateway-kt/x402/eth/address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need paginated on-chain transaction data for a specific Ethereum address and want a reliable blockchain explorer backend (Blockchain.info) with x402 micropayment access. Prefer this over self-hosted node queries when you lack direct Ethereum node access, or over generic block explorer scraping when you need structured JSON output with controlled pagination.
Side effects
- Invalid or malformed Ethereum address returns an error or empty result
- Network identifier mismatch (e.g. submitting a BTC address for ETH) causes lookup failure
- Page or size values outside allowed ranges (size > 50 or page < 0) return validation errors
- Payment failure (x402 payment not accepted) blocks the request
- Rate limiting or gateway timeout if the explorer backend is slow
- Address with no transaction history returns an empty results set
