How this service works
Landing pages ($15), Google Sheets/Apps Script automation ($10), scrapers, scripts & Telegram bots (from $15), broken-link + sitemap audit reports ($10). See a working demo first, pay after.
Output
Returns a JSON object containing: transaction hash, status (success/failed/pending), sender and recipient addresses, ETH value transferred, block number and timestamp, number of confirmations, gas used, method ID, transaction fee in both ETH and USD, chain ID, and an array of ERC-20 token transfers (each with from/to/token address/amount/symbol).
Example use cases
Verify a USDC payment completed
“I just sent someone USDC on Base — can you check transaction 0x20215b4a54f0a39995f3afbd748d7b52c3a1922685ddf08e5f694ea1e89b52bf and confirm it went through with the correct amount and recipient?”
Debug a failed DeFi transaction
“My Base transaction 0x20215b4a54f0a39995f3afbd748d7b52c3a1922685ddf08e5f694ea1e89b52bf might have failed — can you look it up and tell me the status, gas used, and block number so I can figure out what went wrong?”
Audit ERC-20 transfers in a transaction
“Can you fetch the details of Base tx 0x20215b4a54f0a39995f3afbd748d7b52c3a1922685ddf08e5f694ea1e89b52bf and list all the ERC-20 token transfers that happened in it, including the token addresses, senders, recipients, and amounts?”
Technical details
Endpoint
GEThttps://quickbuild.quynguyenbac.workers.dev/api/base/tx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to inspect a specific Base (chain ID 8453) transaction by hash, particularly when you need decoded ERC-20 transfer data, USD fee estimates, and confirmation counts in a single call. Prefer this over a generic Ethereum block explorer when working specifically with the Base L2 network and needing structured JSON output suitable for agent consumption.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash not found on Base chain returns not-found error
- Network or RPC node unavailability causes timeout
- Payment of 0.002 USDC not provided results in 402 response
- Pending transactions may have incomplete block/confirmation data
