How this service works
Use when you need to confirm whether a Base mainnet transaction hash succeeded, reverted, is pending or does not exist, with block, confirmations, sender, recipient, gas used and total fee in ETH (L2 plus L1 data fee). Read-only, public blockchain data.
Output
Returns the transaction status (success, reverted, pending, or not found), the block number it was included in, the number of confirmations, sender and recipient addresses, gas used, and the total fee in ETH broken down into L2 execution fee and L1 data fee.
Example use cases
Confirm a payment landed on Base
“I just sent some USDC on Base — can you check if transaction 0xabc123def456789012345678901234567890abcdef1234567890abcdef123456 succeeded or is still pending?”
Debug a failed smart contract call
“My contract interaction on Base seems to have failed. Can you look up tx hash 0x9f8e7d6c5b4a3210fedcba9876543210fedcba9876543210fedcba9876543210fe and tell me whether it reverted and how much gas was consumed?”
Audit gas fees paid on a Base transaction
“Can you pull up the details for Base transaction 0x1234abcd5678ef901234abcd5678ef901234abcd5678ef901234abcd5678ef90 — specifically the total ETH fee including the L1 data component and the L2 execution fee?”
Technical details
Endpoint
GEThttps://biosfera.46-62-215-147.sslip.io/o/base-tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to verify a Base mainnet (chain ID 8453) transaction and require both L2 execution fee and L1 data fee breakdown alongside confirmation count and participant addresses. Prefer this over generic block explorers when operating programmatically in an agent workflow that needs structured JSON output rather than HTML.
Side effects
- Transaction hash not found on Base mainnet — returns does-not-exist status
- Malformed hash (not matching ^0x[0-9a-fA-F]{64}$) results in validation error
- Transaction is still pending — status returned as pending with no block/gas data yet
- Network or RPC unavailability may cause timeout or service error
- Hash from a different chain (e.g. Ethereum mainnet) will return not found
