Coin search
GET https://agent402.tools/api/coin-search
Resolve a name or ticker to coin ids: full-text search returning matching coins (id, symbol, name, market cap rank, ordered by rank), exchanges (id, name, market type) and categories (id, name), plus NFT collections. `limit` per group 1-50 (default 10). The id resolver for every other coin tool: an agent holding "PEPE" or "render" gets the canonical id here before calling coin-profile, coin-ohlc or coin-history. Cached in-process for 5 minutes.
Warnings

How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
