# Wintergreen x402 Everything-Plus Bundle

> Wintergreen x402 Everything-Plus Bundle is a paid API for AI agents from x402.wintergreen.uk, paid per call via x402, $0.01/call, status down (last checked 2026-09-15).

Returns a comprehensive bundle of crypto trading intelligence, quant methodology, market microstructure insights, power market data, and career guides — gated by a $49 USDC micropayment via x402 on Base.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-everything-plus-bundle-80feac10
```

Example prompt: Pull the full Wintergreen everything-plus bundle — I want Hyperliquid funding divergence signals, the quant kill-battery rules, and the crypto microstructure observations; go ahead and authorize the $49 USDC payment on Base to unlock it.

## When to prefer this

Choose this endpoint when an AI agent needs a broad, one-shot retrieval of Wintergreen's entire intelligence corpus — trading signals, quant methodology, microstructure data, and power market content — and is capable of handling x402 micropayment flows on Base. Prefer it over narrower endpoints when the use case spans multiple categories (e.g., both Hyperliquid signals and quant methodology) and the $49 flat fee is economically justified versus calling multiple individual endpoints.

## Known failure modes

- HTTP 402 returned if payment header is missing or invalid — must sign EIP-712 TransferWithAuthorization and retry with X-PAYMENT header
- Payment to wrong address or wrong chain (must be Base / eip155:8453) causes rejection
- Insufficient USDC balance causes payment failure
- Malformed X-PAYMENT header format causes 400/402 error
- Response schema is unspecified — content structure may vary or change without notice
- $49 per-call cost makes repeated polling expensive

## How this service works
