Example use cases
Confirm customer crypto payment received
“I need to confirm that a customer's USDC payment came through — the tx hash is 0x4fa2...8c1d, they should have sent 25.00 USDC to my wallet 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7 from 0xABCDEF1234567890abcdef1234567890abcdef12 on Base mainnet. Can you verify the receipt?”
Audit invoice payment on Base Sepolia
“Check if this test payment went through on Base Sepolia — tx hash 0x9f3a...2b77, it was supposed to be 1.00 USDC from 0xTestPayer11223344556677889900aabbccddeeff to 0xTestPayee00ffeeddccbbaa9988776655443322 with invoice ID INV-2024-007.”
Dispute resolution for missed payment
“A vendor is claiming they never received payment — the tx hash on Base is 0xde4c...11ab, amount should be 150.00 USDC from 0xOurWallet1122334455667788990011223344556 to their wallet 0xVendorWallet6677889900112233445566778899. Can you pull the receipt and tell me if it checks out?”
Technical details
Endpoint
POSThttps://beggar-bot-demand.beggarbot.workers.dev/v1/receipt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to cryptographically verify a specific USDC transaction on Base mainnet or Base Sepolia — particularly when confirming that a payment from a known payer reached a known payee for a specific amount. Prefer this over generic block explorer lookups when you need structured, machine-readable receipt validation with optional invoice matching.
Side effects
- Invalid or malformed tx_hash returns an error
- Transaction not found on the specified network
- Mismatch between on-chain data and provided payee/payer/amount details
- Payment of $0.01 USDC required via x402 protocol before the response is returned; missing payment returns 402
- Unsupported network value other than 'base' or 'base-sepolia'
- Invalid Ethereum address format for payee or payer fields
