## 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 api-messari-io-88f78fab
```

Example prompt: Pull the full Messari asset detail snapshots for bitcoin and ethereum — I want rich metrics on both of them.

## When to prefer this

Use this endpoint when you need comprehensive, rich metric snapshots for one or more specific crypto assets by their Messari IDs or slugs. Prefer this over narrower endpoints (like ATH, ROI, or mindshare) when you want a broad all-in-one data snapshot rather than a specific metric slice. Ideal for portfolio analysis, asset research, or powering dashboards that need deep per-asset data.

## Known failure modes

- Invalid or unrecognized asset IDs/slugs return empty or error results
- Payment failure (402) if x402 payment of 0.1 USDC is not processed
- Request with neither ids nor slugs may return an error or empty response
- Rate limiting if too many assets are requested simultaneously
- Network timeout for very large multi-asset requests
