## How to call it through Zero

```sh
zero fetch --capability yellowstone-thermal-features-registry-f86549e2
```

Example prompt: Pull up the Yellowstone Thermal Features registry from Naturepedia — I need the full structured list of geysers, hot springs, mud pots, fumaroles, and hydrothermal systems including thermophiles and microbial mat data.

## When to prefer this

Choose this endpoint when you need a comprehensive, structured, machine-readable registry of Yellowstone thermal features with ecological relationships — especially when you need JSON-LD formatted data covering geysers, hot springs, fumaroles, mud pots, thermophiles, and microbial mats in a single call. Prefer this over general web searches when you need canonical, curated, and deduplicated data about Yellowstone's hydrothermal systems.

## Known failure modes

- Missing or invalid 'resource' query parameter returns an error
- Payment not processed (x402 protocol) results in 402 Payment Required response
- Network timeout if the registry server is unavailable
- Malformed resource URL may return empty or error response
- Stale data if the registry hasn't been updated recently

## How this service works

Paid machine-readable Yellowstone Thermal Features registry connecting geysers, hot springs, mud pots, fumaroles, Old Faithful, Grand Prismatic Spring, thermophiles, microbial mats, hydrothermal systems, and Yellowstone thermal ecology.

## Output

A JSON-LD structured document with @context, @type, name, description, and a systems array containing records for Yellowstone thermal features (geysers, hot springs, mud pots, fumaroles), including thermophile and microbial mat ecological data, with canonicalKeepCount and duplicateRemovedCount metadata.
