How this service works

86 APIs for AI agents: web scraping and crawling to Markdown, AI summaries, data extraction and cited answers, screenshots and PDF, PDF, OCR and document conversion, news, paper and developer search and more, paid per call with USDC on Base, Solana, Polygon or Arbitrum via x402. No account, no API key, free sample on every service.

Output

Returns a JSON object with full transaction details: sender and recipient addresses, transaction hash, chain, nonce, success/fail status, ETH fees paid, chain ID, a block explorer URL, gas used, method ID, timestamp, value in ETH, block number, confirmations count, an array of token transfers (each with from/to, token contract, amount, and symbol), contract creation address if any, and effective gas price in gwei.

Example use cases

Verify USDC payment confirmation

“I sent a USDC payment on Base — the transaction hash is 0x387b8fce2e62d9466a30840c5f391b7511968bca9b73280c17aefe29d63eb82c. Can you check if it succeeded and how many confirmations it has so far?”

Audit on-chain token transfer

“Look up transaction 0x387b8fce2e62d9466a30840c5f391b7511968bca9b73280c17aefe29d63eb82c on Ethereum and give me the full breakdown — from/to addresses, any token transfers, gas paid, and the timestamp.”

Debug failed blockchain transaction

“My transaction on Base with hash 0x387b8fce2e62d9466a30840c5f391b7511968bca9b73280c17aefe29d63eb82c might have failed — can you fetch its status, gas used, and the block it landed in?”

Technical details

Endpoint

POSThttps://agentsvc.io/api/v1/proxy/evm-tx?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need fast, structured on-chain transaction details for a specific hash on Base or Ethereum without setting up your own RPC node or API key. Ideal for agents that need to verify payment settlement, audit token transfers, or confirm transaction finality as part of an automated workflow, paid per-call with no subscription required.

Side effects

Invalid transaction hash format (must match ^0x[0-9a-fA-F]{64}$) returns a validation error
Transaction hash not found on the specified chain returns a not-found error
Network issues or RPC node timeouts may result in a delayed or failed response
Specifying the wrong chain (e.g. Ethereum vs Base) for the transaction will return no data
