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.

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.

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.
