How this service works
200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
Returns a JSON object with the transaction hash, status (success/failed/pending), block number, chain name, sender address (from), recipient address (to), gas used, and number of confirmations.
Example use cases
Confirm a USDC payment landed
“Did my USDC transfer go through? Check the status of this Base transaction hash 0x045cfeb395a5de639fbaced3788106c2d8fd5aee4777eff058425fad6a76c166 and tell me how many confirmations it has.”
Audit gas used after contract call
“I just called a smart contract on Ethereum — can you pull up the transaction details for 0x045cfeb395a5de639fbaced3788106c2d8fd5aee4777eff058425fad6a76c166 and tell me how much gas was used?”
Monitor pending transaction confirmation
“Keep an eye on transaction 0x045cfeb395a5de639fbaced3788106c2d8fd5aee4777eff058425fad6a76c166 on Base and let me know once it's confirmed with enough confirmations to be considered final.”
Technical details
Endpoint
GEThttps://fastx402.tools/evm-tx-status?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, account-free, pay-per-call lookup of EVM transaction status on Base or Ethereum without setting up API keys. Prefer it over block explorer scraping or free RPC calls when you need structured JSON output with confirmation counts inside an agent workflow.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash not found on the specified chain
- Unsupported chain value (only 'base' and 'ethereum' accepted)
- Network or RPC timeout when querying chain state
- Payment failure via x402 if USDC balance is insufficient
