Air Compressor API

healthy 3,866 Subscribers

Compressed-air maths as an API, computed locally and deterministically — the receiver, pump-up and SCFM numbers a pneumatics tech or shop owner sizes a system with. The receiver-size endpoint gives the tank you need to ride out a demand burst: volume = demand (free-air CFM) × minutes × 14.7 ÷ the usable pressure window (max − min) — pulling 20 CFM for a minute over a 175-to-100 psi window wants about a 30-gallon receiver, the buffer that lets the pump catch up. The pumpup endpoint gives the time to raise a receiver from one pressure to another: volume × pressure rise ÷ (14.7 × compressor CFM), so a 60-gallon tank from 100 to 175 psi on a 15 CFM compressor takes about 2.7 minutes. The scfm endpoint corrects actual CFM to standard CFM for the inlet conditions — SCFM = ACFM × (inlet pressure ÷ 14.696) × (528 ÷ inlet temperature in Rankine) — so a compressor at 5,000 feet delivers about 17 % fewer SCFM than at sea level, the reason you size tools on SCFM, not the nameplate. Everything is computed locally and deterministically, so it is instant and private. Ideal for pneumatics and shop-air apps, compressor-sizing and tool-demand tools, industrial-air calculators, and trade aids. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Estimates — duty cycle and the pump curve shift real numbers.

Industrial Coatings API — oanor API marketplace

Industrial Coatings API

Industrial and protective-coatings maths as an API, computed locally and deterministically — the film-build numbers a coatings inspector, painter or estimator works to, the ones simple paint estimating skips. The coverage endpoint gives theoretical and practical coverage from the coating's volume solids and the target dry film thickness: coverage = 1604 × the volume-solids fraction ÷ the DFT in mils, where 1604 is the square feet a gallon covers at one mil — so a 50 %-solids coating at 2 mils dry covers about 401 ft² per gallon, less a loss factor for overspray and surface profile. The film-thickness endpoint converts between wet and dry film thickness through the volume solids: WFT = DFT ÷ the solids fraction, because the solvent flashes off and the film shrinks, so a 50 %-solids coating laid 4 mils wet dries to 2 mils — the number you check with a wet-film comb as you spray. The transfer-efficiency endpoint gives the real material needed: theoretical gallons ÷ the transfer efficiency, since conventional spray lands only ~25 % on the part, HVLP ~65 %, electrostatic up to ~95 %. Everything is computed locally and deterministically, so it is instant and private. Ideal for coatings-estimating and inspection apps, industrial-painting and protective-coating tools, NACE/SSPC study aids, and spec calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. For simple wall-paint area estimating use a paint API.

 Tank Volume API — oanor API marketplace

Tank Volume API

Tank volume and fill-level maths as an API, computed locally and deterministically. The volume endpoint gives the total capacity — in litres, US gallons and cubic metres — of a vertical cylinder, horizontal cylinder, rectangular tank, sphere or capsule, from its dimensions in metres, centimetres, millimetres, feet or inches. The fill endpoint computes the volume of liquid and the percent full at a given fill depth, using the exact geometry for each shape — including the circular-segment formula for a horizontal cylinder (where the level is famously non-linear) and the spherical-cap formula for a sphere. The level endpoint is the inverse "dipstick" calculation: it finds the depth that corresponds to a target volume or a target percentage, solving the segment geometry by bisection. Everything is computed locally and deterministically, so it is instant and private. Ideal for fuel, water, oil and chemical tank monitoring, agriculture and irrigation, process and industrial tooling, and tank-gauging and dipstick apps. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is tank-gauging geometry; for swimming-pool volume and chemical dosing use a pool API, and for plain unit conversion use a unit-conversion API.

 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.
