## 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-content-broker-everything-bundle-50595b7d
```

Example prompt: Pull the full Wintergreen intelligence bundle — I want the Hyperliquid funding divergence signals, liquidation clusters, and quant kill-battery strategy rules all in one shot. Go ahead and authorize the $9.99 USDC payment on Base to unlock it.

## When to prefer this

Choose this endpoint when an AI agent needs a broad, one-call bundle of crypto trading intelligence (Hyperliquid signals, microstructure, quant methodology) plus ancillary content (power markets, career guides) and is capable of executing an x402 EIP-712 micropayment on Base. Prefer it over piecemeal data sources when cost-per-call economics favor a $9.99 all-in bundle over multiple subscriptions.

## Known failure modes

- HTTP 402 returned if payment header is absent or invalid — agent must sign EIP-712 TransferWithAuthorization and retry with X-PAYMENT header
- Payment to wrong address or wrong chain (must be Base eip155:8453) results in failed authorization
- Insufficient USDC balance causes payment failure and 402 loop
- Malformed X-PAYMENT header returns 400 or 402
- Rate limiting or server downtime may cause 5xx errors
