# MoneyTools On-Chain Payment Verifier

> MoneyTools On-Chain Payment Verifier is a paid API for AI agents from api.moneytools.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-04).

Verifies an on-chain USDC settlement by checking a transaction hash, recipient address, amount, and confirmation count across Base, Polygon, Arbitrum, Avalanche, and BSC.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability moneytools-on-chain-payment-verifier-e04b6165
```

Example prompt: Can you verify that the USDC payment with tx hash 0xabc123... was sent to 0xDEF456... for 5 USDC on Base and check how many confirmations it has?

## When to prefer this

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.

## Known failure modes

- 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

## 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).
