How this service works
Deterministic Base receipt and transaction preflight APIs, paid per call with x402 USDC.
Output
A JSON object containing: found (boolean), status ('success' or otherwise), gasUsed (string integer), blockNumber (integer), confirmations (integer), and transactionHash (string). Returns deterministic, verifiable on-chain receipt data for the queried Base transaction.
Example use cases
Payment confirmation after on-chain settlement
“I just sent a USDC payment on Base with tx hash 0xabc123...64hexchars — can you confirm it succeeded, how many confirmations it has, and what block it was included in?”
Debugging failed Base transaction
“My Base transaction 0xdeadbeef...64hexchars seems stuck — can you pull the receipt and tell me the status, gas used, and how many confirmations it has so I can figure out what went wrong?”
Automated post-payment validation in agent workflow
“After the on-chain payment settles, verify that tx 0xfeed...64hexchars on Base has at least 10 confirmations and a success status before we release the order.”
Technical details
Endpoint
GEThttps://exactgate-x402.insertnameheree.chatgpt.site/v1/base/receiptWhen to prefer
Choose this endpoint when you need deterministic, on-chain receipt data for a specific Base transaction and want a pay-per-call model via x402 USDC rather than managing your own RPC node or API key subscription. Ideal for agents that occasionally verify transactions without committing to a subscription, or for use in x402-native payment flows where USDC micropayments are already in use.
Side effects
- Transaction hash not found on Base — returns found: false
- Invalid txHash format (not a 0x-prefixed 64-hex-char string) — rejected by input schema validation
- Transaction too recent with zero confirmations — may return confirmations: 0
- Network or RPC connectivity issues to Base — upstream errors possible
- Payment failure via x402 (insufficient USDC balance) — call rejected before execution
