Food Recognition API

From a photo to structured nutrition

Most "food recognition" returns only a label — you still have to map that label to nutrition yourself. TastyAPI does both in one request: it recognizes the dish and returns the nutrition for the portion it sees, so a single call is enough to log a meal.

What it handles

• Prepared meals and plated dishes — the everyday photos people actually take of their food.
• Packaged products and raw ingredients — from a snack wrapper to a single piece of fruit.
• Portion estimation from context — nutrition scales to the amount visible, not a fixed 100 g.
• Allergen and dietary flags — gluten, dairy, and vegan/vegetarian/gluten-free booleans in the same response.

Where it fits

• Photo-based food logging. Replace manual search-and-select with a single snapshot — the highest-friction step in any diet app.
• Fitness and coaching apps. Auto-fill macros for a meal from the photo a user already shares.
• Restaurant and delivery. Generate nutrition estimates for dish photos across a catalog.
• Health assistants. Add a vision "what am I eating?" capability to a chatbot or agent.

Accuracy and image tips

The model is trained on tens of millions of food images and returns calibrated estimates, typically within 10–15% of laboratory analysis. Recognition is strongest on clear, well-lit photos where the whole dish is visible. Heavy occlusion, extreme angles, or very mixed plates lower confidence — for those, a follow-up text call to the Nutrition API with a short description can refine the result. Estimates are for tracking and information, not medical use.
