## 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 nexusapi-hash-verify-1269db2d -d '<json body>'
```

Example prompt: Can you verify that the hash 'e3b0c44298fc1c149afb...' matches the string 'hello world' — I want to confirm the data hasn't been tampered with.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call hash verification without setting up API keys or managing infrastructure — ideal for ad-hoc integrity checks in automated pipelines using USDC micropayments on Base.

## Known failure modes

- Invalid or malformed hash format returns an error response
- Missing required query parameter causes 400 bad request
- Unsupported hash algorithm returns an unsupported operation error
- Mismatched hash returns a false/invalid result rather than an error
- Payment failure (402) if USDC payment is not included or insufficient
