Example prompt: I've been struggling with poor sleep after my evening weightlifting sessions — I wake up around 3am and can't get back to sleep. My training schedule has me lifting 4 days a week with a long run on Saturdays. Can you give me an HRV-based sleep plan, a supplement protocol, and any CBT-I techniques that fit my schedule to fix this?

## When to prefer this

Choose this endpoint when the user is an athlete or fitness-focused individual seeking to improve recovery sleep quality, specifically when they want HRV-informed guidance combined with supplements and CBT-I behavioral strategies — rather than generic sleep hygiene advice or medical diagnosis. Ideal for performance agents handling athlete recovery workflows.

## Known failure modes

- Missing or vague sleep issue may result in generic recommendations
- Incomplete training schedule information may reduce personalization quality
- Service unavailability may return a 402 Payment Required if payment fails
- Malformed input parameters may return a 400 Bad Request
- Timeout if the generation takes longer than expected under load
