## 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 blockchain-iq-crypto-index-data-4db1279a
```

Example prompt: Pull up the Blockchain IQ 'ai-agents' index and show me all the member coins with their current prices, 24-hour changes, and market caps.

## When to prefer this

Choose this endpoint when you need analyst-curated, thematic cryptocurrency index data — specifically the composition and live market metrics for a named index basket. Prefer it over generic coin-list APIs when the user wants a pre-screened, research-backed grouping of coins (e.g. 'AI tokens', 'Layer 2s') rather than a raw market-cap ranking. It's ideal when the user cares about thematic exposure and wants per-coin price, change, and volume data in a single call.

## Known failure modes

- Invalid or unknown slug returns no data or 404-equivalent error
- Stale or delayed market data if upstream price feeds lag
- Malformed slug (e.g. spaces instead of hyphens) may fail to match any index
- Payment failure (insufficient USDC balance) blocks the request via x402 protocol
- Index may have zero members if newly created or deprecated

## How this service works

Analyst-verified crypto research for individual investors — without the institutional price tag.

## Output

Returns a JSON object containing the index name and slug, plus an array of member coins each with: coin ID, name, symbol, rank, current price in USD, all-time high in USD, 24-hour percentage change, 30-day percentage change, market cap in USD, and 24-hour trading volume in USD. Also includes terms URL, source attribution, and a disclaimer that data is not investment advice.
