How this service works
Factual directory of x402 pay-per-call services run by MoneyTools for AI agents, plus referral/affiliate links we hold. Contains referral links.
Output
Returns a JSON object with: a boolean 'valid' field indicating overall settlement validity, a 'verdict' string ('valid' or a failure reason), a 'confirmations' number showing how many block confirmations the transaction has received, and a 'reasons' array listing any specific validation failures (e.g. wrong amount, wrong recipient, insufficient confirmations).
Example use cases
Gate content after crypto payment
“Someone just sent me USDC on Base — tx hash is 0x9f3a...b2c1, they were supposed to pay 10 USDC to my wallet 0x1234...abcd. Can you verify the payment is confirmed before I give them access?”
Automate x402 payment settlement check
“Before I fulfill this order, check that tx hash 0xdeadbeef... on Polygon sent exactly 2.5 USDC to 0xSeller...wallet and that it has at least 12 confirmations.”
Audit historical USDC transfer on Arbitrum
“I need to confirm an old USDC payment on Arbitrum — the tx hash was 0x7777...aaaa, it should have sent 50 USDC to address 0xRecipient...5566. Was it valid?”
Technical details
Endpoint
GEThttps://api.moneytools.dev/v1/verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify that a specific on-chain USDC payment has settled correctly — matching recipient, amount, and confirmation threshold — across Base, Polygon, Arbitrum, Avalanche, or BSC. Prefer this over manual block explorer lookups when automating payment-gated workflows, x402 settlement confirmation, or order fulfillment triggers. It is especially suited for agents that need to validate crypto payments before releasing digital goods, API access, or service fulfillment.
Side effects
- Transaction hash not found on specified network — returns valid: false with reason
- Amount mismatch between on-chain transfer and requested amount — returns valid: false
- Recipient address does not match payTo parameter — returns valid: false
- Insufficient confirmations — returns valid: false with current confirmation count
- Network not supported or RPC timeout — may return error or valid: false
- Malformed tx hash or wallet address — returns validation error
