{"openapi":"3.1.0","info":{"title":"Crypto Trending API","version":"1.0.0","description":"What the crypto market is searching for right now, served live from the public CoinGecko trending feed with no key. This is hype and attention data — distinct from market-cap rankings, exchange tickers and DeFi feeds — surfacing the coins, NFT collections and categories with the biggest spike in search interest over the last 24 hours. The coins endpoint returns the trending coins ranked by search popularity, each with its live USD price, 24-hour change, market cap, 24-hour volume, market-cap rank and BTC price. The nfts endpoint returns the trending NFT collections with floor price (native and display), 24-hour floor change and 24-hour volume. The categories endpoint returns the trending narratives and sectors with market cap, volume and 24-hour change. Trending means ranked by CoinGecko search popularity, so rank 1 is the single most-searched asset of the moment — exactly the signal traders, bots and dashboards use to catch a move early. Read live from CoinGecko, nothing stored beyond a short protective cache. Ideal for crypto dashboards, trading bots, sentiment and hype trackers, and discovery feeds. Live, no key. 3 trending endpoints. For full price history use an OHLC or exchange API.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/cryptotrending-api","description":"oanor gateway"}],"tags":[{"name":"Trending"},{"name":"Meta"}],"components":{"securitySchemes":{"oanorKey":{"type":"apiKey","in":"header","name":"x-oanor-key","description":"Get your key at https://www.oanor.com/developer/keys"}}},"security":[{"oanorKey":[]}],"paths":{"/v1/categories":{"get":{"operationId":"get_v1_categories","tags":["Trending"],"summary":"Trending categories / narratives","description":"","parameters":[{"name":"limit","in":"query","required":false,"description":"Max categories to return (default 10, max 30)","schema":{"type":"string"},"example":"10"}],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK"},"401":{"description":"Missing or invalid x-oanor-key header"},"402":{"description":"Active subscription required"},"429":{"description":"Rate-limit or monthly quota reached"},"502":{"description":"Upstream did not respond"}}}},"/v1/coins":{"get":{"operationId":"get_v1_coins","tags":["Trending"],"summary":"Trending coins by search popularity","description":"","parameters":[{"name":"limit","in":"query","required":false,"description":"Max coins to return (default 15, max 30)","schema":{"type":"string"},"example":"15"}],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK"},"401":{"description":"Missing or invalid x-oanor-key header"},"402":{"description":"Active subscription required"},"429":{"description":"Rate-limit or monthly quota reached"},"502":{"description":"Upstream did not respond"}}}},"/v1/nfts":{"get":{"operationId":"get_v1_nfts","tags":["Trending"],"summary":"Trending NFT collections","description":"","parameters":[{"name":"limit","in":"query","required":false,"description":"Max collections to return (default 10, max 30)","schema":{"type":"string"},"example":"10"}],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK"},"401":{"description":"Missing or invalid x-oanor-key header"},"402":{"description":"Active subscription required"},"429":{"description":"Rate-limit or monthly quota reached"},"502":{"description":"Upstream did not respond"}}}},"/v1/meta":{"get":{"operationId":"get_v1_meta","tags":["Meta"],"summary":"Spec","description":"","parameters":[],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK"},"401":{"description":"Missing or invalid x-oanor-key header"},"402":{"description":"Active subscription required"},"429":{"description":"Rate-limit or monthly quota reached"},"502":{"description":"Upstream did not respond"}}}}},"x-oanor-pricing":[{"slug":"free","name":"Free","price_cents_month":0,"monthly_call_quota":5000,"rps_limit":2,"hard_limit":true},{"slug":"starter","name":"Starter","price_cents_month":740,"monthly_call_quota":95000,"rps_limit":5,"hard_limit":true},{"slug":"pro","name":"Pro","price_cents_month":2150,"monthly_call_quota":520000,"rps_limit":15,"hard_limit":true},{"slug":"business","name":"Business","price_cents_month":4900,"monthly_call_quota":3100000,"rps_limit":40,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/cryptotrending-api"}
