Example prompt: What's the current crypto market pulse — is it frothy with crowded longs, a capitulation setup, or somewhere neutral? Give me the combined mood, attention, and funding tilt read.

## When to prefer this

Use this endpoint when you need a fast, no-key, multi-factor crypto market read that goes beyond a single Fear & Greed number. Prefer it over raw Fear & Greed APIs when you want leverage context (funding tilt and open interest) combined with attention signals in a single synthesized stance. Ideal for pre-trade context checks, automated risk management workflows, and daily market briefings where a structured label (frothy/capitulation_setup/risk_on/risk_off/neutral) is more actionable than a raw numeric index.

## Known failure modes

- Upstream data unavailability for one or more of the three input signals may cause degraded or stale output
- Network or server errors returning non-200 HTTP responses
- Edge cases where all three signals are ambiguous may default to neutral stance regardless of actual conditions
- As a gauge and not a trading signal, the stance may lag rapid intraday market moves

## How this service works

One trading-grade read where the single Fear & Greed number isn't enough. Combines three independent angles: mood (Fear & Greed), attention (what's trending), and leverage (OI-weighted perp funding tilt market-wide). The edge is the combination — greed + crowded longs = froth/long-squeeze risk; fear + crowded shorts = capitulation/short-squeeze setup. Returns a stance (frothy / capitulation_setup / risk_on / risk_off / neutral). One call, no key. A gauge, not a signal. Not financial advice.

## Output

Returns a single composite market stance label — one of: frothy, capitulation_setup, risk_on, risk_off, or neutral — derived from three independent signals: Fear & Greed index (mood), trending topic attention (attention), and OI-weighted perpetual futures funding rate across the market (leverage tilt). The stance summarizes whether the market shows signs of overleveraged longs (froth/long-squeeze risk) or oversold shorts (capitulation/short-squeeze setup).
