## 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 marine-intelligence-q-a-marine-x402-press-f3ed4c22 -d '<json body>'
```

Example prompt: What are the expected wave heights and swell conditions around Cape Horn this week, and is it safe for a mid-sized sailing vessel to attempt the passage?

## When to prefer this

Choose this endpoint when you need synthesized, conversational marine intelligence covering a range of topics — wave conditions, port info, vessel characteristics, and safety — in a single call. Prefer it over raw weather APIs when the user needs interpreted guidance rather than raw numerical data, or when the query spans multiple maritime domains simultaneously. Best suited for sailors, maritime professionals, and vessel operators seeking quick expert-level answers without needing to consult multiple specialized databases.

## Known failure modes

- Vague or ambiguous questions may yield generic answers without specific local data
- Real-time wave or weather data may not be current if underlying sources are delayed
- Questions outside the marine domain may return unhelpful or off-topic responses
- High server load or payment processing issues may cause timeouts
- Obscure or very local port data may not be available in the training sources

## How this service works

Multi-source marine intelligence via DeepSeek — wave conditions, port info, vessel types, maritime safety.

## Output

A natural language response synthesized from multiple marine data sources and the DeepSeek model, covering wave conditions, port details, vessel specifications, maritime regulations, or safety guidance depending on the question asked. Responses are conversational and informative, not raw data feeds.
