How this service works
320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.
Output
An array of matching cryptocurrency token objects, each containing the token's ID, name, symbol, and market cap rank. Results are ordered by relevance to the search query.
Example use cases
Identifying top token by name
“Can you search for 'ethereum' in the crypto token database and tell me its market cap rank and official symbol?”
Finding token ID for downstream use
“I need the token ID and market cap rank for 'chainlink' — can you look it up so I can use it in another crypto API call?”
Exploring tokens by keyword
“Search for all crypto tokens with 'dog' in the name and list their symbols and market cap rankings.”
Technical details
Endpoint
POSThttps://whatchuneed.vercel.app/api/token/searchWhen to prefer
Use this endpoint when you need to quickly look up cryptocurrency tokens by name or symbol and retrieve their market cap rank, especially in a pay-per-call context via x402 protocol. Prefer this over broader market data APIs when you need lightweight token identification without full OHLCV or historical data.
Side effects
- Empty results array if no tokens match the query string
- Missing or null market_cap_rank for tokens not ranked in top markets
- 400 or validation error if 'query' field is absent from the request body
- Payment failure (402) if x402 protocol payment is not correctly attached
- Ambiguous results when query matches many tokens (e.g. searching 'b')
