## When to prefer this

Use this endpoint when an AI agent needs a quick, single-call classification of current market sentiment regime without managing API keys or accounts. Prefer over raw CNN Fear & Greed scraping or manual indicator aggregation. Ideal for agents making autonomous trading decisions, portfolio risk gating, or generating market commentary that needs a sentiment anchor. The pay-per-use USDC model suits infrequent or event-driven queries rather than high-frequency polling.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- Malformed request body — returns 400 Bad Request
- Upstream data provider unavailable — returns 502 or 503
- Rate limiting or account issues — returns 429

## How this service works

The combined market regime — one read fusing the stock Fear & Greed score and velocity, VIX, insider-buying sentiment, and net liquidity into a named regime (e.g. Mixed Signals) with severity and a suggested stance, plus how the S&P 500 historically performed after similar regimes (forward 5/22-day and 1/3-month returns and win rates). From x402stock, a market & economic data API (x402, USDC).

## Output

Returns a regime classification for current US equity market sentiment (e.g. fear, greed, neutral, extreme fear, extreme greed) likely with a numeric score and timestamp, reflecting aggregated market sentiment indicators
