Output
Returns a pack of curated content — which may include AI agent prompts, trading datasets, or market analysis materials — corresponding to the requested pack name and category. The response schema is open-ended, so the exact structure of returned content (e.g. JSON objects, prompt strings, dataset records) depends on the specific pack requested.
Example use cases

Technical details
Endpoint
GEThttps://x402.wintergreen.uk/api/v1/prompts/packWhen to prefer
Choose this endpoint when you need pre-curated, payment-gated AI agent prompts or trading/market analysis datasets and are willing to pay a small USDC micropayment per access. It is especially useful for agents that need high-quality, structured prompt packs for financial or trading workflows without building their own prompt libraries. Prefer this over free or open prompt repositories when quality-gating and micropayment-based access control are acceptable.

- Invalid or unknown pack identifier — may return empty or error response
- Invalid category value — may return no results or an error
- Network timeout or service unavailability — generic 5xx error
