How this service works
Blockchain explorer gateway — Solana, Bitcoin, Bitcoin Cash, Ethereum
Output
Returns a JSON object containing detailed Ethereum transaction data including sender, receiver, value, gas used, block number, status, and — if the transfers flag is set to true — an array of ERC-20 token transfer events that occurred within the transaction.
Example use cases
Verify a received crypto payment
“I just got notified of an ETH payment — can you pull up transaction 0xabc123def456...789 on the Ethereum network and confirm the amount and recipient address?”
Trace ERC-20 token movements
“Look up Ethereum transaction 0x7f3d9c2b1a8e4f6d0c5b2a9e7f4d1c8b5a2e9f6c3b0a7e4d1c8b5a2 and include all ERC-20 token transfers so I can see which tokens moved.”
Audit DeFi swap transaction
“Fetch the details for Ethereum transaction 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d on ETH network, with token transfers included — I want to verify what tokens were swapped in this DeFi transaction.”
Technical details
Endpoint
POSThttps://api.blockchain.com/explorer-gateway-kt/x402/eth/transaction?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to retrieve structured Ethereum transaction data programmatically, especially when you also need ERC-20 token transfer details bundled in a single call. Prefer this over generic block explorer scraping when you need machine-readable JSON output. Choose this over Etherscan's API if you want a unified multi-chain gateway (Solana, Bitcoin, Bitcoin Cash, Ethereum) from a single provider with pay-per-use x402 micropayment pricing.
Side effects
- Invalid or malformed transaction ID returns an error or empty response
- Transaction not found on the specified network returns 404 or null result
- Wrong network specified (e.g. passing a Bitcoin txId for ETH network) causes lookup failure
- Rate limiting or payment failure (x402) blocks the request
- Network congestion or node unavailability causes timeout
