Output
A regime classification for the requested crypto symbol, likely including the current market state label (e.g. trending, ranging, risk-on/off, high/low volatility) and potentially supporting metadata such as confidence or regime scores. Response is only returned after successful USDC micropayment via x402.
Example use cases
Regime-gated strategy selection
“Before placing any trades today, check what quant regime BTC is in — I want to know if we're trending or ranging so I can pick the right strategy.”
Live trading bot regime filter
“My trading bot needs to know the current market regime for ETH before it opens a position — can you fetch that signal and only proceed if we're in a trending regime?”
Multi-symbol regime scan
“Check the quant regime for SOL right now — I need to know if it's in a high-volatility or mean-reverting state before I adjust my Hyperliquid position sizing.”
Technical details
Endpoint
GEThttps://x402.wintergreen.uk/api/v1/quant/regime?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quantitative market regime label for a specific crypto symbol in real time, especially when building regime-aware trading strategies on Hyperliquid or similar venues. Prefer it over general sentiment or price APIs when you need a structured quant classification (trending/ranging/volatility state) grounded in microstructure signals. Best suited for AI agents capable of handling x402 micropayment flows on Base.
Side effects
- HTTP 402 returned if payment header is missing or invalid — must sign EIP-712 TransferWithAuthorization and retry with X-PAYMENT header
- Invalid or unsupported symbol returns an error or empty response
- Network timeout if Base blockchain authorization is slow
- Malformed payment signature causes rejection
- No response schema documented — output structure may be opaque to agents without prior calls
