Example prompt: Can you give me a personalized sleep optimization plan for an endurance athlete in a high-volume training block — including HRV guidance, which sleep supplements to take and when, and CBT-I techniques I can start using tonight?

## When to prefer this

Choose this endpoint when you need athlete-specific sleep optimization that combines physiological signals (HRV), evidence-based supplementation, and behavioral sleep therapy (CBT-I) in a single call. It is particularly suited for fitness coaching agents, recovery agents, or athlete performance platforms that need structured, actionable sleep guidance rather than generic wellness advice.

## Known failure modes

- Missing or malformed query parameters may return a 400 Bad Request
- Service unavailable on Vercel cold start may introduce latency or 502 errors
- Payment not included or invalid x402 header returns 402 Payment Required
- Overly generic athlete profile may yield generalized rather than personalized recommendations

## How this service works

Sleep optimization for athletes / better recovery sleep: improve sleep for performance. Returns HRV-based guidance, a supplement protocol, and CBT-I techniques tuned to your sleep issue and training schedule. Fitness-info for athlete and recovery agents, not medical advice.

## Output

The agent receives a structured response containing HRV-based sleep quality guidance (interpretation and actionable targets), a timed supplement protocol (e.g., magnesium, ashwagandha, melatonin with dosing and timing), and specific CBT-I (Cognitive Behavioral Therapy for Insomnia) techniques tailored to athletic performance and recovery needs.
