## 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-x402-ecosystem-health-dashboard-87d5ba0e
```

Example prompt: Pull the ecosystem health dashboard from Wintergreen — I need the latest crypto microstructure overview including funding divergence and liquidation cluster data, and I'm happy to pay the USDC fee via x402.

## When to prefer this

Choose this endpoint when an AI agent needs structured, curated crypto trading intelligence or quant methodology content that is not available from free public sources, and when the agent is capable of executing x402 micropayments in USDC on Base. Prefer over generic market data APIs when the use case involves Hyperliquid-specific signals, walk-forward backtesting methodology, or detailed microstructure observations like liquidation clusters and regime detection.

## Known failure modes

- HTTP 402 returned if USDC payment via EIP-712 TransferWithAuthorization on Base is not provided or invalid — agent must sign and retry with X-PAYMENT header
- Invalid or missing _route_slug or _file_slug may return empty or incorrect content
- Payment address mismatch or wrong chain (must be Base eip155:8453) causes payment failure
- Rate limiting or endpoint unavailability may result in non-200 responses
