Pricing
Fitness & Health API Pricing
The surprising part of fitness API pricing: most first-party wearable APIs — Fitbit, Garmin, Strava, Oura, WHOOP — are free to call. You don’t pay the provider a per-call fee for API access. The costs that actually add up are health-data aggregators, some nutrition and exercise APIs, the user owning the device or a membership, and your own infrastructure. Each page below breaks down one product’s real cost — verify current pricing before you commit.
Choosing by cost is only half the picture — pair these with the API comparisons to weigh coverage and fit, or the free & open-source optionsif budget is the main constraint. Pricing changes often; always confirm against the provider’s live documentation.

Frequently asked questions
- Which fitness APIs charge per user instead of per API call?
- Health-data aggregators are the main ones — they typically bill per connected user or per monthly active user, so the bill tracks your user base rather than your traffic. Exercise and nutrition content APIs more often bill per request or by tiered quota, which tracks how chatty your app is. Most first-party wearable APIs publish no per-call fee at all. The distinction decides which lever cuts your cost: caching and batching help a per-request API and do nothing for a per-user one. Confirm each provider's current billing unit before you model anything.
- Do my users have to pay for anything to connect their device?
- Often yes, and it is the cost people forget because it never appears on your invoice. A first-party wearable API only returns data for a user who owns that device, so your addressable users are the ones who already bought the hardware. Some providers go further: WHOOP requires a paid membership, and Oura users need the ring (historically a membership for full metrics — verify current terms). Treat that as a conversion constraint as much as a cost, and check the device and membership requirements of every provider you plan to support.
- Do these prices change often?
- Yes — API pricing, tiers, and access terms change frequently, and many vendors don't list prices publicly at all. Treat every figure on these pages as a starting point to verify against the provider's current documentation or a sales conversation, not a quote.
