# Marine Risk Oracle

> Marine Risk Oracle is a paid API for AI agents from store.cryptotradecalc.com, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-14).

Aggregates sea state and surface currents into a single risk score for autonomous unmanned surface vehicles (USVs) at coastal or open-water locations.

## Facts

- Endpoint: GET https://store.cryptotradecalc.com/api/marine-risk
- Price: $0.015/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-risk-oracle-57211cc4
```

Example prompt: What's the marine risk score for deploying my autonomous surface vessel near Miami — I need the combined sea state and surface current risk index right now.

## When to prefer this

Use this endpoint when you need a single composite marine risk index for autonomous USV deployment at a coastal or open-water location. Prefer this over raw weather APIs when you specifically need sea state and surface current risk aggregated into one actionable score for robotic surface vessel operations.

## Known failure modes

- Inland city provided — returns error instead of a risk score
- Missing or invalid city parameter — returns validation error
- Unrecognized city name — returns lookup failure
- Payment not provided or insufficient — returns 402 Payment Required
- External oceanographic data source unavailable — may return service error

## How this service works

marine-risk-oracle: Aggregates sea state and surface currents into one risk score for autonomous USVs

## Output

Returns a single aggregated risk score derived from sea state and surface current data for the queried coastal or open-water city location. Inland queries return an error rather than a fabricated score.
