## 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-funding-divergence-analysis-0df64bbc
```

Example prompt: Pull the latest funding rate divergence data from Wintergreen's quant endpoint so I can see where the biggest spreads are in crypto perpetuals right now.

## When to prefer this

Choose this endpoint when you need low-cost ($0.01 USDC) on-demand funding rate divergence data for crypto perpetual markets and can handle x402 micropayment flows. Best suited for agents with USDC payment capability that need quant signals without a subscription. Avoid if you need a guaranteed schema, SLA, or high data reliability — the undocumented response schema and low crawl quality score indicate this is a hobbyist or early-stage service.

## Known failure modes

- 402 Payment Required if x402 payment header is missing or USDC payment fails
- Empty or minimal response schema makes parsing unpredictable
- Rate limiting or access denial if payment is not properly settled
- Service may be unavailable or return stale data given low crawl quality score
- Response format may change without notice as schema is undocumented
