Pet Food & Calorie API

healthy 4,208 Subscribers

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.

Dog & Cat Age API — oanor API marketplace

Dog & Cat Age API

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.

 Dog Breeds & Images API — oanor API marketplace

Dog Breeds & Images API

Dog-breed images and the full breed taxonomy via the open Dog CEO collection — no key. The breeds endpoint returns every breed with its sub-breeds (e.g. hound → afghan, basset, blood, …). The images endpoint fetches a batch of photos for a given breed and optional sub-breed, and the random endpoint pulls a batch of random dog photos from across all breeds. Real images straight from the Dog CEO dataset, with the breed list cached for speed — no key. 4 endpoints. Ideal for pet apps, placeholder imagery, breed pickers, quizzes and fun UI seeding.

 Fruit Nutrition API — oanor API marketplace

Fruit Nutrition API

Fruit nutrition and botanical taxonomy as an API, built on the open Fruityvice dataset. Get every fruit with its scientific classification — family, genus and order — and its per-100g nutrition: calories, sugar, carbohydrates, protein and fat. Look up a single fruit by name, list every fruit in a botanical family (e.g. Rosaceae), genus (e.g. Prunus) or order (e.g. Rosales), or filter the whole catalogue by a nutrient range — for example all fruits with under 5g of sugar, sorted lowest first. Real data, no key needed upstream. Ideal for nutrition and diet apps, smoothie and recipe tools, health trackers and educational projects.

 BMR & Calorie API — oanor API marketplace

BMR & Calorie API

Energy-expenditure and nutrition maths as an API, computed locally and deterministically. The bmr endpoint computes the basal metabolic rate — the calories the body burns at rest — from weight, height, age and sex, using the modern Mifflin-St Jeor equation (BMR = 10·kg + 6.25·cm − 5·age + 5 for men, −161 for women) and reporting the classic revised Harris-Benedict value alongside for comparison. The tdee endpoint computes the total daily energy expenditure, TDEE = BMR × an activity factor from sedentary (1.2) to very active (1.9), and the goal calories for maintenance, mild and standard weight loss and weight gain — a 500 kcal/day deficit or surplus is about 0.45 kg per week. The macros endpoint splits a calorie target into protein, fat and carbohydrate grams, with protein set per kilogram of bodyweight (4 kcal/g protein and carbs, 9 kcal/g fat). Everything is computed locally and deterministically, so it is instant and private. Ideal for fitness, nutrition and health-app developers, diet and meal-planning tools, gym and coaching apps, and wellness dashboards. Pure local computation — no key, no third-party service, instant. Live, nothing stored. Estimates only, not medical advice. 3 endpoints. This is metabolic-rate and calorie maths; for body-mass-index use a BMI calculator.
