## 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-market-odds-content-broker-fe684e66
```

Example prompt: Pull the Hyperliquid funding divergence signals content from Wintergreen — the slug is 'hyperliquid-funding-divergence' — and pay the $0.001 USDC fee automatically.

## When to prefer this

Choose this endpoint when an AI agent needs on-demand access to specialized crypto trading intelligence, quantitative methodology, or niche market content gated behind a per-call USDC micropayment. It is ideal for agents with x402-capable payment infrastructure on Base that need to fetch specific content by slug without a subscription. Prefer this over subscription APIs when call volume is low or content needs are ad hoc.

## Known failure modes

- Missing or invalid slug returns an error or empty response
- Missing X-PAYMENT header triggers HTTP 402 with payment instructions
- Insufficient USDC balance or invalid EIP-712 signature causes payment rejection
- Unknown slug with no matching content returns empty or 404-style response
- Base network congestion may delay payment confirmation
- Stale or replayed payment authorization rejected by facilitator

## Output

The agent receives the content payload associated with the requested slug — which may be a detailed trading signal report, quantitative methodology document, crypto microstructure observation set, power market analysis, or other intelligence product. The response schema is open-ended, so content format varies by slug. A 402 response with payment details is returned first if the USDC authorization header is missing or invalid.
