How this service works
Full asset data for one or more slugs (agent-optimized).
Output
Returns a structured, agent-optimized payload for each requested slug containing fields such as current price (USD), market capitalization, rank, circulating supply, max supply, 24h volume, and other asset metadata. Data is formatted for easy agent consumption without requiring additional parsing.
Example use cases
Portfolio snapshot across multiple coins
“Get me the full asset details from CoinCap for bitcoin, ethereum, and chainlink — I want current price, market cap, circulating supply, and rank for each.”
Single asset deep-dive for research
“Fetch all available CoinCap data for the polkadot slug — price, volume, market cap, supply, everything you can get.”
Crypto dashboard data feed
“I'm building a crypto dashboard — grab the full asset data from CoinCap for cardano, avalanche, and polygon so I can populate the stats cards.”
Technical details
Endpoint
GEThttps://rest.coincap.io/v3/agentFriendly/full_assets_by_slugWhen to prefer
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.
Side effects
- 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
