## 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 liquid-logic-x402-wallet-allowance-checker-6b6ed3c7
```

Example prompt: Before I pay that x402 endpoint, check whether the Liquid Logic treasurer wallet 0xEA24bafbBAF6d7Ba58bE860EE906f0Fe533d167D is allowed to pay https://some-x402-api.com/data and tell me how much USDC I have left under today's daily cap.

## When to prefer this

Use this endpoint when you need a low-cost ($0.001 USDC) pre-flight authorization check before committing to a more expensive x402 API call. Prefer this over the full /api/audit endpoint ($0.05) when you only need allowance and remaining cap data rather than a complete spend history. Ideal for agent workflows that must gate payments behind budget or allowlist validation.

## Known failure modes

- Missing wallet parameter returns a validation error
- Invalid or malformed wallet address returns an error
- Endpoint URL not on allowlist returns denied/unauthorized status
- Daily cap fully consumed returns zero remaining allowance
- Network or service downtime may return 5xx errors

## How this service works

Call this BEFORE paying an x402 endpoint: ask whether the Liquid Logic treasurer wallet (0xEA24…) is allowed to pay that URL and how much USDC remains under the UTC daily cap. $0.001 USDC on Base — cheaper than /api/audit ($0.05). Pass wallet; optionally pass endpoint. Omit endpoint for wallet-level remaining + allowlist. Site: https://liquidlogicx.com

## Output

Returns the allowance status (whether the wallet is permitted to pay the given endpoint), the remaining USDC amount under the UTC daily spending cap, and optionally a summary of the wallet's full allowlist if no specific endpoint is provided.
