MyFitnessPal

MyFitnessPal is a nutrition and fitness tracking platform built around a food diary, calorie counting, a large branded-food and barcode database, exercise logging, weight and body measurements, and goal setting. Its partner-facing REST API (v2, hosted at api.myfitnesspal.com) lets approved applications read and write a consenting user's diary (food and exercise), body measurements, and profile, and subscribe to webhook notifications when that data changes. Access uses OAuth 2.0 authorization-code grants with the diary, measurements, private-exercises, and subscriptions scopes. The developer program is currently closed to new applicants. This profile was surfaced as a portfolio lead and enriched by the API Evangelist pipeline.

MyFitnessPal publishes 1 API on the APIs.io network: API v2. Tagged areas include Company, Consumer, Health and Fitness, Nutrition, and Fitness Tracking.

The MyFitnessPal catalog on APIs.io includes 1 event-driven AsyncAPI specification.

MyFitnessPal’s developer surface includes documentation, API reference, engineering blog, support, pricing, signup flow, and 11 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/myfitnesspal: open an issue to ask a question, or submit a pull request to add artifacts.
