Build with Ascend.

We expose the open parts of our system, exercise + food databases, share-card renderer, mountain registry. No paywall for read-only. Auth keys free, rate-limited at 60 req/min.

Example, fetch an exercise

curl -H "Authorization: Bearer YOUR_KEY" \
  https://api.getascend.club/v1/exercises/barbell-back-squat

{
  "slug": "barbell-back-squat",
  "name": "Barbell Back Squat",
  "primary": ["quadriceps", "glutes"],
  "secondary": ["hamstrings", "core", "spinal-erectors"],
  "equipment": ["barbell", "squat-rack"],
  "form_notes": ["...", "..."],
  "variations": ["front-squat", "goblet-squat"]
}

Why open?

Most fitness apps lock their exercise + food databases inside the app. We think those are commodities, the value Ascend ships is the AI coach, mountain progression, anatomy heatmap, and gamification. Anyone should be able to build something useful with our taxonomy.

SDK + OSS

· @ascend/share-card-renderer, render PR / mountain / league SVG cards client-side (planned npm)
· @ascend/exercises-client, typed TS client for the exercises endpoint (planned)
· @ascend/anatomy-heatmap, React component, taxonomy-aware (planned)

These modules are planned for after launch; the repos aren't public yet.
