Example prompt: Give me a full research deep-dive on Solana — I want the 30-day price action context, range analysis, derivatives positioning with funding and open interest, volatility observations, and the current technical state all in one report.

## When to prefer this

Use this endpoint when you need a comprehensive, narrative-style multi-section research brief on a single coin rather than raw metrics or a trading signal. It is ideal for generating human-readable context about price action, derivatives positioning, and technical state in one call. Prefer this over the ML trading signal endpoint when you want explanatory research rather than a directional signal, and over the price endpoint when you need structured analytical context rather than just numbers.

## Known failure modes

- Unsupported coin symbol returns an error or empty response
- Cache may serve data up to 6 hours old, which may not reflect rapid market moves
- LLM generation errors could result in incomplete or malformed sections
- High demand may cause latency spikes beyond the typical fast profile
- Payment failure (x402) blocks the request before generation
