## 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 agentoracle-payment-settlement-verifier-66a2951d
```

Example prompt: Can you verify the AgentOracle payment transaction 0x3a2f1b...e94d and tell me whether it's confirmed on-chain, who paid, how much, and how many block confirmations it has?

## When to prefer this

Use this endpoint when you need to verify a specific payment transaction that was previously recorded by AgentOracle on Base, especially in autonomous agent workflows where payment confirmation is required before proceeding. It is ideal for post-payment audits, dispute resolution, and settlement verification for x402-protocol payments. Prefer this over generic blockchain explorers when you need AgentOracle's recorded metadata (route, recorded status, USD amount) alongside the raw on-chain state.

## Known failure modes

- Invalid or malformed txHash (not matching 0x + 64 hex chars) returns a validation error
- Transaction hash not found in AgentOracle records returns a 404 or empty result
- On-chain state may return 'unavailable' if the Base RPC is temporarily unreachable
- Transaction may be in 'pending' state if not yet mined or confirmed
- Payment to this API endpoint itself may fail if USDC balance is insufficient (x402 protocol)

## How this service works

AgentOracle: verify a payment transaction recorded by AgentOracle and check its Base receipt confirmation state. Returns recorded amount, payer, recipient, route, timestamp, and confirmed, pending, reverted, or temporarily unavailable on-chain state.

## Output

Returns a JSON object containing the transaction hash, payer address, recipient address, amount in atomic units and USD, asset type, network, payment route, recorded timestamp, recorded status, and an on-chain object with state (confirmed, pending, reverted, or unavailable), block number, confirmation count, check timestamp, and an optional reason field.
