How this service works
Search CoinCap assets by name or symbol (agent-optimized).
Output
Returns a list of matching cryptocurrency assets from CoinCap, each including the asset's canonical slug, name, and symbol — which can then be used as input to other CoinCap endpoints like price history, MACD, or EMA.
Example use cases
Resolve token slug before price lookup
“Search CoinCap for the asset 'chainlink' so I can get its slug and then pull the historical price series.”
Verify a coin exists on CoinCap
“I want to check if there's an asset on CoinCap matching the symbol 'MATIC' — can you search for it and tell me what comes back?”
Identify ambiguous token by name
“There's a token called 'shiba' — can you search CoinCap to see which assets match that name and give me their identifiers?”
Technical details
Endpoint
GEThttps://rest.coincap.io/v3/agentFriendly/assets_searchWhen to prefer
Use this endpoint when you have a cryptocurrency name or ticker symbol and need to resolve it to a CoinCap asset slug before calling other CoinCap endpoints (price history, MACD, EMA, market cap). This is the discovery step in a multi-step CoinCap workflow. Prefer this over guessing slugs directly.
Side effects
- Empty result set when no assets match the search string
- Ambiguous results when a common keyword matches many tokens
- Rate limiting or payment failure (x402) if the $0.004 USDC call fee is not satisfied
- Missing or malformed 'search' query param returning unexpected results
