FAQ

Common questions

What's the response time?

Under a second for full program generation. Single session endpoints are faster.

Is there a free tier?

Not currently. The Basic plan at $0.99/mo gives you 1,000 requests with full access to every feature. You can test endpoints in the RapidAPI playground before subscribing.

Will the price go up?

Yes. Current pricing is introductory. As new themes and features ship, prices will increase. We plan to keep existing subscribers at their current rate.

Can I request new anime themes?

Yes. More themes are in the works. Ultra subscribers get early access. Reach out with requests and they'll get bumped up.

What format does the API return?

Structured JSON with typed fields. Every response includes program metadata, session structure, exercise details with sets/reps/RPE/load/tempo, themed names, and character coaching cues.

Do I need to handle authentication myself?

No. RapidAPI handles API keys and billing. You just include your RapidAPI key in the header and make requests.

Can AI agents use this API?

Yes. The structured JSON output works as tool call responses for AI agents. Pass natural language requests through your agent, map to API parameters, return the program.
