## 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 xynaptic-battery-metals-brief-f6bd76f9
```

Example prompt: Give me today's battery metals brief — lithium, copper, platinum, palladium, aluminum, and silver spot prices with their daily moves, and tell me what the composite EV supply-chain tension verdict is.

## When to prefer this

Choose this endpoint when you need a pre-composed, analyst-grade snapshot of EV battery and catalyst metals in a single call rather than fetching individual commodity prices. It is ideal when you want the composite supply-chain tension verdict alongside raw prices — especially for EV sector monitoring, portfolio briefings, or automated market commentary workflows where multiple metals must be assessed together.

## Known failure modes

- Unknown or misspelled asset names in ?assets= param may cause empty or partial results
- Market data source outage may return stale or null price fields
- Exceeding rate limits or failed x402 payment may return 402 Payment Required
- Requesting an asset outside the supported set may yield no data for that metal

## How this service works

Xynaptic Battery Metals Brief — the EV-transition metals reading in one call: lithium, copper, platinum, palladium prices with daily moves, plus aluminum and silver — the battery and catalyst chain — and a composite tension verdict for EV supply chains. GET no params (optional ?assets=lithium,copper).

## Output

A structured snapshot containing spot prices and daily percentage moves for up to six metals (lithium, copper, platinum, palladium, aluminum, silver), plus a composite tension verdict summarizing the overall EV supply-chain signal derived from those price movements.
