# Wintergreen Quant Resolved Signals

> Wintergreen Quant Resolved Signals is a paid API for AI agents from x402.wintergreen.uk, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).

Returns real-time resolved Hyperliquid trading signals (funding divergence, lead-lag, liquidation clusters, session volume areas) for a given coin, gated by x402 micropayment.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability wintergreen-quant-resolved-signals-de506ba2
```

Example prompt: Pull the resolved Hyperliquid trading signals for BTC right now — I want to see the funding divergence, liquidation clusters, and session volume areas before I place my trade.

## When to prefer this

Choose this endpoint when you need real-time, quantitatively-derived Hyperliquid-specific signals (funding divergence, liquidation clusters, lead-lag, volume areas) for a specific coin and are operating in an x402 micropayment-capable agent environment. Prefer over generic crypto data APIs when Hyperliquid microstructure signals and walk-forward-validated quant methodology matter, and when per-call cost of $0.02 USDC is acceptable.

## Known failure modes

- HTTP 402 returned if valid X-PAYMENT header is missing or payment authorization is invalid
- Empty or null response if the coin symbol is not recognized or not traded on Hyperliquid
- Stale or no signal if market data feed is unavailable
- Invalid EIP-712 signature causes payment rejection and 402 response
- Unknown coin parameter returns empty or error response

## Output

A JSON response containing resolved trading signals for the requested coin, which may include funding rate divergence readings, lead-lag correlation values, liquidation cluster price levels, and session volume area levels derived from Hyperliquid microstructure data. The endpoint is payment-gated via x402, requiring a $0.02 USDC micropayment on Base before the signal payload is returned.
