## 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 x402-hub-tide-check-b62331a8 -d '<json body>'
```

Example prompt: What are today's high and low tide times for Santa Monica Beach? I need the full tide schedule.

## When to prefer this

Use this endpoint when you need quick tide schedule lookups — high/low times and heights — for a specific coastal location, beach, harbor, or tide station. Prefer this over general weather APIs when tidal data specifically is required for marine, fishing, surfing, or coastal navigation use cases.

## Known failure modes

- Unrecognized location or station name in query returns no data or an error
- Ambiguous query string may return data for the wrong location
- Upstream tide data provider outage causes empty or error response
- Payment failure via x402 protocol results in 402 Payment Required response
- Malformed query field returns validation error
