Rule, applied in order: published-price when the vendor lists a price for any paid developer plan; no-published-price when it names a paid plan or commercial terms without a price; free when it says developer access costs nothing and names no paid plan. line is the vendor's sentence the class rests on and url its page; freeEntry is a line showing a free plan, trial or sandbox; unpricedTier a line naming a paid tier without a price. The generator fails unless each line is a substring of a quote in the named evidence file. The class describes what the vendor's page states on the evidence files' read dates, not what a customer pays. A vendor whose lines state no price either way, or KinesteX, which funds this site, is listed with the reason in excluded and left out of the counts. ## Fields | Field | Description | JSON types | Null in | |---|---|---|---| | `vendor` | The vendor | string | 0 of 32 rows | | `category` | wearable, aggregator, nutrition, exercise, motion or gym | string | 0 of 32 rows | | `categoryLabel` | The category's name | string | 0 of 32 rows | | `class` | published-price, no-published-price or free (see methodology); null when excluded | null, string | 7 of 32 rows | | `classLabel` | The class's name | null, string | 7 of 32 rows | | `line` | The vendor's line the class rests on, verbatim from the evidence file | null, string | 7 of 32 rows | | `url` | The vendor page the line is quoted from | null, string | 7 of 32 rows | | `evidenceFile` | The evidence file holding the quote | null, string | 7 of 32 rows | | `freeEntry` | A vendor line showing a free plan, trial or sandbox; null where none is quoted | null, string | 20 of 32 rows | | `unpricedTier` | A vendor line naming a paid tier without a price; null where none is quoted | null, string | 24 of 32 rows | | `excluded` | Why the vendor is left out of the counts; null when counted | null, string | 25 of 32 rows | | `pricingPage` | This site's pricing page for the vendor | string | 0 of 32 rows | A null means the source does not state the value or it could not be verified. It never means zero, and it is never a guess. In the CSV a null is an empty unquoted field. ## Update cadence - `src/data/researchStudies.ts` is maintained by hand alongside the pages it feeds; this dataset is regenerated from it with `npm run datasets` in the change that edits it, so it moves when the site's pages move. - The files are rebuilt by `npm run datasets` (scripts/build-datasets.mjs); a run with no source change writes byte-identical files. The edition stays 2026.1, and a new edition ships under a new file name rather than overwriting this one. ## Cite as AIFitnessAPI, "Fitness API Pricing Transparency 2026 (who publishes a price, per vendor)," version 2026.1, aifitnessapi.com, https://aifitnessapi.com/datasets/fitness-api-pricing-transparency-2026.json ```bibtex @misc{aifitnessapi-fitness-api-pricing-transparency-2026, author = {{AIFitnessAPI}}, title = {Fitness API Pricing Transparency 2026 (who publishes a price, per vendor)}, version = {2026.1}, year = {2026}, publisher = {aifitnessapi.com}, url = {https://aifitnessapi.com/datasets/fitness-api-pricing-transparency-2026.json}, note = {Dataset, CC BY 4.0} } ``` Every dataset this site publishes: https://aifitnessapi.com/datasets
