Maple Syrup API

healthy 4,388 Subscribers

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.

Beekeeping API — oanor API marketplace

Beekeeping API

Beekeeping and apiary maths as an API, computed locally and deterministically — the mite, brood and winter-stores numbers a beekeeper manages a hive with. The varroa endpoint turns an alcohol-wash or sugar-shake count into the infestation rate: mites per 100 bees = mite count ÷ bees sampled × 100, where a half-cup scoop is about 300 bees, and it flags when the colony crosses the treatment threshold (commonly 3 mites per 100 bees, or 3 %). The brood endpoint projects the development calendar from the day an egg is laid: it hatches around day 3, the cell is capped around day 8–10 and the adult emerges on day 16 for a queen, 21 for a worker and 24 for a drone — so a worker egg laid on the 1st emerges three weeks later. The stores endpoint sizes winter honey: how many kilograms the colony needs by climate (about 12 kg mild to 35 kg harsh), the equivalent full deep frames (~2.25 kg each), and the deficit and frames to feed against the current stores. Date arithmetic is exact. Everything is computed locally and deterministically, so it is instant and private. Ideal for beekeeping, apiary-management, homestead and agriculture app developers, hive-inspection and mite-monitoring tools, and beekeeping education. Pure local computation — no key, no third-party service, instant. Dates as YYYY-MM-DD; metric weights. Live, nothing stored. 3 compute endpoints. A planning aid — local conditions vary.

Programming Languages API — oanor API marketplace

Programming Languages API

The language definitions GitHub uses to recognise code (the open-source Linguist data) as an API — a clean reference for syntax highlighting, file-type detection, repository dashboards and developer tooling. For each of 800+ languages the API returns its type (programming, markup, data or prose), its brand colour (the hex GitHub paints it), the file extensions associated with it, common aliases, the GitHub language id and the editor (ace) mode. Look a language up by name or alias (golang resolves to Go), reverse-look-up which language(s) own a file extension (.py → Python; .h → C, C++, Objective-C), list the languages of a type, search, or list them all. Distinct from languages-api (ISO 639 human languages) — this is the programming-language reference. Served from memory — always fast.

MIME Types API — oanor API marketplace

MIME Types API

The canonical MIME / media-type database (the jshttp mime-db used by Express and most of the Node ecosystem: IANA + Apache + nginx), served from memory — no key. Resolve a media type to its file extensions, charset and compressibility; reverse-lookup the media type(s) for a file extension (e.g. png → image/png); and search or list types by source. 2,600+ media types, 1,000+ with file extensions. Lean, predictable JSON. Ideal for upload validation, Content-Type resolution, file-type detection, download handlers and developer tooling.

MusicBrainz API — oanor API marketplace

MusicBrainz API

The open music-metadata database as an API — artists, release-groups (albums), releases, recordings and labels, identified by stable MusicBrainz IDs (MBIDs), returned as clean JSON. Search any entity by name or Lucene query; look up an artist with their external links and tags, an album, a release with its full track list, a recording with its ISRCs, or a label; and browse an artist's complete discography. Live data with MBIDs, disambiguations, types, countries, life spans, ISRCs, barcodes, catalogue numbers and relations — the canonical identifiers that link and de-duplicate music data across services. Ideal for metadata enrichment and matching, music catalogues, tagging and library tools, and research. 11 data endpoints. Authenticated with an x-oanor-key; fair-use rate limits per plan.
