How this service works
Blockchain explorer gateway — Solana, Bitcoin, Bitcoin Cash, Ethereum
Output
Returns a JSON object containing a paginated list of transactions associated with the specified Ethereum address, including details such as transaction hashes, timestamps, amounts, counterparties, and status — along with pagination metadata indicating total count and current page.
Example use cases
Audit wallet transaction history
“Can you fetch all recent transactions for Ethereum address 0xAbCd1234...5678 on the ETH network? Show me the first 20 results.”
Monitor DeFi portfolio activity
“I need to see the on-chain transaction records for my Ethereum wallet 0x1a2b3c4d...ef01 — grab page 2 with 50 transactions per page on ETH.”
Investigate suspicious wallet
“Look up the blockchain transaction history for Ethereum address 0xDead...Beef on the ETH network, starting from the first page with 20 entries, so I can review what it's been doing.”
Technical details
Endpoint
POSThttps://api.blockchain.com/explorer-gateway-kt/x402/eth/address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need paginated, on-chain Ethereum transaction history for a specific wallet address via a trusted, blockchain.com-backed explorer gateway. It is well-suited for auditing wallet activity, monitoring DeFi interactions, or investigating address behavior on the ETH network. Prefer it over raw node RPC calls when you want a clean REST API with structured JSON output and no need to manage a full node.
Side effects
- Invalid or malformed Ethereum address returns a 400 error
- Unsupported network value causes a validation error
- Page number out of range returns empty results or an error
- Payment failure (x402) blocks access if USDC payment is not provided
- Rate limiting or network timeouts may cause 503 or timeout responses
- Address with no transaction history returns an empty result set
