How this service works
Daily calories for a dog or cat from weight, species and life stage (neutered adult, weight loss, working, young).
Output
Returns the daily energy requirement (DER) in kcal/day, the underlying resting energy requirement (RER), the life stage multiplier factor, a treat allowance in kcal, meal kcal after accounting for treats, a ±20% recommended range, a plain-language summary, source reference, and a veterinary disclaimer. May also include degraded-mode flags if data quality is limited.
Example use cases
Daily calories for overweight cat
“My cat is on a weight-loss plan and currently weighs 6.2 kg — can you calculate her daily calorie target using the weight-loss life stage?”
Puppy feeding calorie guide
“I have a young puppy who's about 3 months old and weighs 4 lb — can you figure out how many kcal per day he needs using the puppy-kitten-young stage? Use pounds.”
Working dog energy requirement
“My border collie does light herding work and weighs 18 kg — what's his daily energy requirement for a light-work life stage, and what's the ±20% range I should keep in mind?”
Technical details
Endpoint
GEThttps://pet-calc.x402tookit.com/daily-energy?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, formula-based daily caloric recommendation for a dog or cat that accounts for life stage (including weight loss, working, and puppy/kitten stages) and returns a breakdown with treat allowance and meal kcal — rather than a generic pet nutrition article or food-bag feeding guide.
Side effects
- Missing required 'species' or 'weight' query parameters returns an error
- Invalid species value (not 'dog' or 'cat') causes a validation failure
- Negative or zero weight returns an error or nonsensical result
- Invalid lifeStage enum value may fall back to default 'neutered-adult' or return an error
- Payment failure (x402) blocks the request entirely
