Pet-age conversion as an API, computed locally and deterministically. The dog endpoint converts a dog’s age in years to a human-equivalent age three ways: the modern epigenetic model from the 2019 UCSD DNA-methylation study, human = 16·ln(dog_age) + 31 (valid from age 1), which makes a 1-year-old dog about 31, a 4-year-old about 53 and a 10-year-old about 68 human years; the American Kennel Club size-based table for small, medium, large and giant breeds, interpolated between yearly anchor points so a large breed ages faster late in life; and the old ×7 rule of thumb for comparison. The cat endpoint converts a cat’s age, counting 15 human years in the first year, 24 by the second, and four per year after that, so a 10-year-old cat is about 56. Ages are in years and decimals are allowed. Everything is computed locally and deterministically, so it is instant and private. Ideal for pet, veterinary, animal-shelter, pet-insurance and lifestyle app developers, dog-years and pet-profile widgets, and fun tools. These are estimates for general guidance, not veterinary advice. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 2 endpoints. This is pet-to-human age; for human body metrics use a BMI or body-fat API.

Pet Food & Calorie API
Pet-nutrition maths as an API, computed locally and deterministically — the calorie, portion and water numbers a dog or cat owner, breeder or pet app feeds an animal by. The calories endpoint uses the standard veterinary formula: resting energy RER = 70 × (body weight in kg)^0.75, then daily maintenance MER = RER × a lifestage factor — 1.6 for a neutered adult dog, 1.2 for a neutered cat, 1.0 or 0.8 for weight loss, 2–3 for puppies and 2.5 for kittens — so a 10 kg neutered dog needs about 394 kcal at rest and 630 kcal a day, and a 5 kg neutered cat about 234 and 281. Weight takes kg or pounds, and a custom factor overrides the table. The portion endpoint turns that calorie need into food: daily grams = calories ÷ the food’s energy density (kcal per 100 g, often 350–450 for dry kibble) or cups ÷ kcal per cup, split across meals — so 630 kcal of a 375-kcal/100 g kibble is about 168 g a day, 84 g per meal. The water endpoint gives the daily requirement, roughly 50–60 ml per kg for dogs and 50 for cats. Everything is computed locally and deterministically, so it is instant and private. Ideal for pet-care, veterinary, pet-food, dog- and cat-app developers, feeding-calculator and pet-health tools, and breeder software. Pure local computation — no key, no third-party service, instant. Educational estimates, not veterinary advice. Live, nothing stored. 3 compute endpoints. For dog-age conversion use a different API.

Biorhythm API
Biorhythm calculation as an API, computed locally and deterministically — a fun, for-entertainment model of three sine-wave cycles that supposedly run from the day you are born: a 23-day physical cycle, a 28-day emotional cycle and a 33-day intellectual cycle, each given by sin(2π·days/period). The cycles endpoint computes the three percentages and their phase (rising, falling or a critical zero-crossing where the cycle changes sign) for a given date, plus the average. The range endpoint returns the daily values over a window of up to 60 days from a start date, ready to plot as three sine waves. The compatibility endpoint compares two birthdates and gives, for each cycle, a defined heuristic compatibility score (1 + cos(2π·Δdays/period))/2 — 100 % when two people's cycles are perfectly in phase and 0 % when exactly opposite — and an overall score. Dates are in YYYY-MM-DD form. Biorhythms have no scientific basis; this is purely an entertainment tool. Everything is computed locally and deterministically, so it is instant and private. Ideal for lifestyle, horoscope, wellness, game and novelty app developers, daily-widget and compatibility tools, and fun dashboards. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is the entertainment biorhythm; for name and birthdate numerology use a numerology API and for star signs a zodiac API.

Zodiac API
Turn a birth date into zodiac signs as an API. Get the Western (tropical) sun sign for any date — its symbol, element (Fire, Earth, Air, Water), quality, ruling planet, polarity, key traits and the signs it is most compatible with (e.g. 15 July → Cancer, Water, ruled by the Moon). Look up a sign by name, get the Chinese zodiac animal, element and yin/yang for any year (e.g. 2020 → Metal Rat), or fetch both Western and Chinese signs from a full birth date at once. Everything is computed locally, so it is fast and always available. Ideal for horoscope and astrology apps, dating and matchmaking, onboarding personalisation, content sites and fun widgets.

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.
