# ForgeMesh Wave Height & Swell Data API

> ForgeMesh Wave Height & Swell Data API is a paid API for AI agents from x402.forgemesh.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns wave height, wave period, swell wave height, and sea surface temperature for any ocean coordinates worldwide from a global marine weather model.

## Facts

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 forgemesh-wave-height-swell-data-api-f3600ca8 -d '<json body>'
```

Example prompt: What are the current wave conditions off the coast of Mavericks — latitude 37.49, longitude -122.50 — including wave height, swell height, wave period, and sea surface temperature?

## When to prefer this

Use this endpoint when you need a quick, single-call snapshot of current sea conditions — wave height, swell, period, and SST — for any ocean point worldwide, especially for shipping logistics, offshore platform planning, recreational boating, or surf forecasting agents.

## Known failure modes

- Invalid or non-ocean coordinates (landlocked location) may return an error or null values
- Missing latitude or longitude fields returns a validation error
- Coordinates outside the model's global coverage may return no data
- Payment failure results in a 402 response before data is returned

## How this service works

Wave height, wave period, swell wave height, and sea surface temperature for any ocean coordinates worldwide, from a global marine weather model. Built for shipping logistics, offshore operations, and recreational boating or surf agents that need current sea conditions in one call.

## Output

Returns wave height, wave period, swell wave height, and sea surface temperature for the requested ocean coordinates, sourced from a global marine weather model.
