Choose this endpoint when you need to programmatically retrieve a specific AI agent prompt, trading signal dataset, or market analysis item from Wintergreen's paid content catalog using a known prompt_id. Prefer this over generic content APIs when you want USDC micropayment-gated access to curated trading and AI agent content, and you already know the content identifier you want.

- 404 Not Found if the prompt_id does not exist
- Invalid prompt_id returns an error or empty response
- Payment protocol mismatch if x402 headers are not correctly formed
- Rate limiting or access denial if the endpoint is overloaded
