## 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 coincap-full-asset-data-by-slug-ecae0fb1
```

Example prompt: Pull the full asset data from CoinCap for bitcoin, ethereum, and solana — I need price, market cap, supply, and rank for all three.

## When to prefer this

Choose this endpoint when you need comprehensive, structured data for one or more specific crypto assets identified by their CoinCap slug — especially when you need multiple data fields (price, supply, rank, volume) in a single call. Prefer this over search endpoints when you already know the slug(s). Use the sibling search endpoint first if you only have a name or ticker and need to resolve the slug.

## Known failure modes

- Invalid or unknown slug returns empty or error result for that asset
- Missing 'slugs' query parameter may return an error or empty dataset
- Rate limiting or payment failure returns 402 or 429 status
- Network timeout if multiple slugs cause slow response
- Slug format mismatch (e.g. using ticker symbol instead of slug) returns no data

## How this service works

## Output
