EXIF API

healthy 4,571 Subscribers

Extract the hidden metadata baked into a photo. Pass an image URL (we fetch it) or a base64 image and get back its EXIF, GPS, IPTC and XMP data: the camera make and model, lens, software, the capture date/time, full exposure settings (shutter speed, aperture / f-number, ISO, focal length, flash, metering and white balance), orientation, colour space and resolution, plus the GPS location (latitude, longitude, altitude) with a ready Google Maps link — and the complete raw tag map. A dedicated /v1/gps endpoint returns just the geotag. Supports JPEG, TIFF, HEIC and PNG. Parsing runs locally (no third-party service) and nothing is stored. Live. 3 endpoints. Built for photo-management apps, geotagging, digital forensics, copyright/credit checks and image pipelines. Distinct from a basic image-info or resize service. No upstream key.

Polyline API

Encode and decode Google/Mapbox encoded polylines — the compact ASCII string used by the Google Maps Directions API, Mapbox, Valhalla, OSRM and GPX-style route geometry to pack a list of coordinates into a few bytes. Decode an encoded string into an array of latitude/longitude points, encode a coordinate list back into a polyline (precision 5, the Google default, or 6 for OSRM/Valhalla overview), and measure a path — point count, total length by the haversine great-circle formula in km and miles, and the bounding box. Perfect for drawing routes on a map, storing tracks compactly, computing trip distance and fitting a map viewport. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. Distinct from coordinate-format conversion (Plus Code/MGRS/UTM) and geohash.

Photography Calculator API

Camera and optics maths as an API. The depth-of-field endpoint computes the near and far limits of sharp focus, the total depth of field and the hyperfocal distance from a focal length, aperture and focus distance, using the circle of confusion for your sensor format — full-frame, APS-C, Micro Four Thirds, 1-inch, medium format, Super 35 and more, or your own value. The field-of-view endpoint gives the horizontal, vertical and diagonal angle of view for a focal length on a given sensor, plus the crop factor and the 35 mm-equivalent focal length. The exposure endpoint computes the exposure value (EV) from aperture, shutter speed and ISO, and can also solve for the shutter speed or aperture that hits a target EV. Everything is computed locally and deterministically, so it is instant and private. Ideal for photography and videography apps, camera and lens tools, focus-stacking and landscape planning, and teaching exposure and optics. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. This computes camera optics; for reading EXIF metadata from photo files use an EXIF API.

Balloon Decor API

Party-balloon maths as an API, computed locally and deterministically — the helium-lift and balloon-count numbers a party planner or balloon artist decorates by. The helium endpoint gives a balloon’s lift from its inflated diameter: net lift is the inflated volume times the difference between air and helium density, about 1.046 grams per litre, so a fully inflated 11-inch latex balloon (around 11.4 litres) lifts roughly 12 grams gross and about 9 after its own weight, while a 36-inch giant lifts hundreds of grams. The float endpoint flips it around — how many balloons to float a payload = the weight divided by the net lift per balloon, rounded up, so a 50-gram card floats on six 11-inch balloons. The garland endpoint sizes an organic balloon garland or arch from its length: about 12 balloons per foot in a mix of sizes — roughly 40 % 5-inch, 45 % 11-inch and 15 % 16-inch for that full, textured look — so a 10-foot garland takes about 120 balloons, denser if you want it lush. Everything is computed locally and deterministically, so it is instant and private. Ideal for party-planning, event-decor, balloon-artist and celebration app developers, decor-estimator and shopping-list tools, and event software. Pure local computation — no key, no third-party service, instant. Inches and grams. Live, nothing stored. 3 compute endpoints.

Grain Bin API

Grain-bin storage maths as an API, computed locally and deterministically — the bushel and weight numbers a farmer or elevator sizes storage by. The bushels endpoint measures a round bin: floor area × grain depth gives the cubic feet, and a cubic foot holds about 0.8036 bushels, so an 18-foot bin filled 20 feet level holds roughly 4,090 bushels — and grain heaped to a peak adds a cone of (1/3) × floor area × peak height, so a 4-foot peak adds about 270 more. The weight endpoint converts bushels to weight by the crop’s standard test weight — corn and sorghum at 56 pounds a bushel, wheat and soybeans 60, oats 32, barley 48 — so those 4,090 bushels of corn weigh 229,040 pounds, about 114.5 US tons or 104 tonnes; pass a measured test weight for light or heavy grain. Everything is computed locally and deterministically, so it is instant and private. Ideal for agriculture, grain-elevator, farm-management and ag-tech app developers, storage-capacity and inventory tools, and harvest software. Pure local computation — no key, no third-party service, instant. US units (feet, bushels, pounds). Live, nothing stored. 2 compute endpoints.
