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.
Example use cases
Monitor AI crypto theme performance
“Show me all the coins in the Blockchain IQ AI Agents index right now — I want to see their current prices, how they've moved in the last 24 hours, and their market caps.”
Research thematic index composition
“What coins does Blockchain IQ include in their DeFi index? Give me the full member list with rankings, symbols, and 30-day price changes.”
Compare index member ATH vs current price
“For the Blockchain IQ layer-2 index, pull up each coin's current price alongside its all-time high so I can see which ones are most discounted from their peaks.”
Technical details
Endpoint
GEThttps://www.blockchainiq.co/api/x402/v1/indices/%7Bslug%7D?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
