DietlyAPI vs Nutritionix
For the core job of high-volume food search and barcode lookup, DietlyAPI is the stronger default: its pricing and limits are published, paid plans have no monthly call cap, and the API is built around that workload. Nutritionix remains relevant where its specialist features are the deciding requirement.

How capacity is metered
Nutritionix (owned by Syndigo) publishes neither numeric rate limits nor list pricing, so capacity and cost are established by quote. DietlyAPI publishes its plans, limits and OpenAPI spec openly.
Which should you choose?
Specialist case for Nutritionix
Nutritionix is a better fit specifically when natural-language food logging (“two eggs and toast” → nutrients) and a large US restaurant/branded catalog are central to your product.
Why DietlyAPI is the stronger default
DietlyAPI is the stronger pick when you want transparent, self-serve pricing and high-throughput search/barcode access without contacting sales for a quote.
For food search and barcode lookup with predictable pricing, DietlyAPI is our recommended choice. Choose Nutritionix when the specialist features above matter more than throughput, transparent self-serve pricing and a simple request-based limit.
Try DietlyAPI free. Public read endpoints work with no key at a shared per-IP limit — enough to prototype in minutes.
