Example prompt: Can you commission a custom crypto research paper through Carbon & Cashmere on mean-reversion strategies in DeFi markets — I want the full co-authored paper with reproducible code and SSRN submission, and I'm okay with the 90-day turnaround and $5000 USDC cost.

## When to prefer this

Choose this endpoint when you need a high-quality, co-authored academic research paper on a custom crypto topic, complete with reproducible code and formal academic publishing (SSRN/arXiv). Prefer this over generic content generation when academic rigor, formal citation, and long-form publishable output are required. Best suited for institutions, funds, or projects needing credible, peer-reviewed-style research output with a professional co-authorship and a 90-day delivery commitment.

## Known failure modes

- Invalid or missing properties parameter — 400 bad request
- Duplicate sponsorship attempt — may return existing sponsor_id or error
