{"openapi":"3.1.0","info":{"title":"Maple Syrup API","version":"1.0.0","description":"Maple-syrup making maths as an API, computed locally and deterministically — the sap-to-syrup yield and finishing numbers a sugarmaker plans a season around. The yield endpoint takes the volume of sap and its sugar content in °Brix and returns the syrup it makes from the sugar balance (syrup = sap × sap °Brix / finished °Brix, finishing at 66.9 °Brix), the water that has to boil off, the sap-to-syrup ratio, and the classic Jones' Rule of 86 (86 ÷ sap °Brix) — the field rule that famously gives about 43 litres of 2 % sap per litre of syrup. The finish endpoint gives the boil-off finishing temperature: syrup is done about 4 °C (7.1 °F) above the boiling point of water, so at sea level that is ~104 °C / 219 °F — calibrate to your own water boiling point, which drops with altitude, and finish that many degrees higher; it also returns the finished density (~66.9 °Brix, SG ≈ 1.337). Everything is computed locally and deterministically, so it is instant and private. Ideal for maple-sugaring, homestead, craft-food and farm app developers, evaporator and yield-planning tools, and sugaring education. Pure local computation — no key, no third-party service, instant. Consistent volume units; temperatures in °C or °F. Live, nothing stored. 2 compute endpoints. A planning aid — a hydrometer or refractometer confirms the finish.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/maple-api","description":"oanor gateway"}],"tags":[{"name":"Maple"},{"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/finish":{"get":{"operationId":"get_v1_finish","tags":["Maple"],"summary":"Finishing temperature","description":"","parameters":[{"name":"unit","in":"query","required":false,"description":"c or f (default c)","schema":{"type":"string"},"example":"c"},{"name":"water_boiling","in":"query","required":false,"description":"Local water boiling point (default 100/212)","schema":{"type":"string"}},{"name":"offset","in":"query","required":false,"description":"Degrees above water (default 4/7.1)","schema":{"type":"string"}}],"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/yield":{"get":{"operationId":"get_v1_yield","tags":["Maple"],"summary":"Sap → syrup yield","description":"","parameters":[{"name":"sap_volume","in":"query","required":true,"description":"Sap volume","schema":{"type":"string"},"example":"100"},{"name":"sap_brix","in":"query","required":true,"description":"Sap sugar content °Brix","schema":{"type":"string"},"example":"2"},{"name":"syrup_brix","in":"query","required":false,"description":"Finished °Brix (default 66.9)","schema":{"type":"string"}}],"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":6950,"rps_limit":2,"hard_limit":true},{"slug":"starter","name":"Starter","price_cents_month":300,"monthly_call_quota":65500,"rps_limit":6,"hard_limit":true},{"slug":"pro","name":"Pro","price_cents_month":830,"monthly_call_quota":258000,"rps_limit":15,"hard_limit":true},{"slug":"mega","name":"Mega","price_cents_month":2650,"monthly_call_quota":1470000,"rps_limit":40,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/maple-api"}
