## 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 rare-earth-tracker-mcp-cecf65b2 -d '<json body>'
```

Example prompt: Can you pull up the latest rare earth element tracking data for neodymium, including current prices and supply chain status?

## When to prefer this

Use this endpoint when you need commodity-level data specifically on rare earth elements, critical minerals, or related supply chain information. Prefer this over generic commodity APIs when the focus is narrowly on rare earth materials used in electronics, batteries, and defense applications.

## Known failure modes

- Missing or empty data field returns validation error
- Unrecognized element name or query may return empty or null results
- Payment failure (402) if USDC balance is insufficient
- Service timeout if upstream data source is unavailable
- Malformed JSON input returns 400 error

## How this service works

## Output

Returns structured data about rare earth elements including pricing, availability, supply chain status, and market metrics based on the query submitted in the data field.
