## 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 quay-tron-payment-verifier-6d0baf4b -d '<json body>'
```

Example prompt: Can you verify that the TRON USDT payment with transaction ID a3f9c2b1d4e8f0a7c5b2e1d9f6a4c8b3d7e0f2a1c6b5d4e3f8a2c9b0d1e7f3a4 actually sent 10 USDT to address TRXxxx...abc on the tron:mainnet?

## When to prefer this

Use this endpoint when you need to verify a TRON-native TRX or USDT payment on-chain — especially in pay-per-call or x402 agent payment flows where you need to confirm a transfer actually reached a specific address before unlocking a resource. Prefer this over generic block explorers when you need a structured JSON response suitable for automated agent decision-making rather than a human-readable UI.

## Known failure modes

- Transaction not found on-chain returns flag='not_found' and success=false
- Network mismatch between provided CAIP-2 network and actual chain returns flag='wrong_network'
- Invalid or malformed txId (non-hex or wrong length) may return an error or not_found
- Amount mismatch where transfer exists but for a different value returns success=false
- Wrong recipient address provided returns not_found or mismatch flag
- Pending/unconfirmed transactions may return 0 confirmations and success=false

## How this service works

Pay-per-call TRON tools. Agents pay USDT on TRON or USDC on Base with x402. The server only receives. The tools still read TRON.

## Output

Returns a JSON object with: a flag string (e.g. 'not_found', 'wrong_network', 'verified'), a success boolean, the token type, a human-readable detail message, and the number of on-chain confirmations for the transaction.
