How this service works
Base transaction lookup by hash - sender, recipient, value, calldata, gas and block, live from Base mainnet via eth_getTransactionByHash.
Output
Returns the full transaction object from Base mainnet: from/to addresses, ETH value, raw calldata, gas limit and price, block number and hash, nonce, and transaction index. Data is live from the chain via eth_getTransactionByHash.
Example use cases
Verify a payment was received on Base
“I just sent a payment on Base — can you check transaction hash 0xd4f8c3e2... and confirm who the sender and recipient were and how much value was transferred?”
Debug a failed DeFi transaction
“I have a Base transaction hash 0x7a91b4f0... — can you pull up the full details including the calldata and gas so I can figure out why it might have failed?”
Audit on-chain activity for compliance
“Can you retrieve all the details for Base transaction 0x3c5e2a1d... — sender, recipient, value, block number, and raw calldata — so I can document it for our audit trail?”
Technical details
Endpoint
GEThttps://x402.agentindex.world/base/tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, live on-chain details for a specific Base mainnet transaction and have its hash. Prefer this over block explorers when building automated workflows, verifying payments programmatically, or extracting calldata for further processing. It is pay-per-call so best suited for targeted lookups rather than bulk scanning (use base-erc20-transfers for range queries).
Side effects
- Transaction hash not found (unconfirmed or invalid hash returns null or 404)
- Malformed hash input causes validation error
- Base mainnet RPC temporarily unavailable returns 5xx
- Transaction in mempool but not yet mined may return empty result
- Incorrect hash format (wrong length or non-hex) rejected at input validation
