{"openapi":"3.1.0","info":{"title":"Stock Short Interest API","version":"1.0.0","description":"Live short-interest data for US stocks from Nasdaq — no key, nothing stored. The \"how heavily is it shorted, and is a squeeze building\" view of a stock: the number of shares sold short, the average daily volume and the resulting days-to-cover, reported each settlement period, distinct from the quote, movers, insider and analyst APIs in the catalogue. The current endpoint returns the latest short-interest reading together with the change from the prior period — a rising or falling short position with the share delta and percent change. The history endpoint returns the full settlement-by-settlement timeline so you can see how the short position has trended over the year. Days-to-cover — short interest divided by average daily volume — is the headline squeeze metric: the higher it is, the longer shorts would need to buy back their position. Build short-squeeze scanners, bearish-positioning dashboards, risk overlays and contrarian-signal bots on top of real Nasdaq short-interest data. Look up any US stock by its ticker; share counts are returned as clean numbers. Note that short interest is reported about twice a month and a few non-Nasdaq listings may not be covered.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/shortinterest-api","description":"oanor gateway"}],"tags":[{"name":"Current"},{"name":"History"},{"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/current":{"get":{"operationId":"get_v1_current","tags":["Current"],"summary":"Latest short interest with change vs prior period","description":"","parameters":[{"name":"symbol","in":"query","required":true,"description":"Stock ticker","schema":{"type":"string"},"example":"AAPL"}],"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/history":{"get":{"operationId":"get_v1_history","tags":["History"],"summary":"Full settlement-by-settlement timeline","description":"","parameters":[{"name":"symbol","in":"query","required":true,"description":"Stock ticker","schema":{"type":"string"},"example":"AAPL"}],"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":"Service metadata","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":11800,"rps_limit":3,"hard_limit":true},{"slug":"starter","name":"Starter","price_cents_month":790,"monthly_call_quota":178000,"rps_limit":10,"hard_limit":true},{"slug":"pro","name":"Pro","price_cents_month":2360,"monthly_call_quota":765000,"rps_limit":28,"hard_limit":true},{"slug":"scale","name":"Scale","price_cents_month":5420,"monthly_call_quota":2780000,"rps_limit":60,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/shortinterest-api"}
