## 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 midax402-market-brief-e262e399
```

Example prompt: Give me a market brief on the x402 ecosystem — specifically how the CDP Facilitator compares to XPay and Circle Nano in terms of request volume and top service categories on Base Mainnet.

## When to prefer this

Use this endpoint when you need a concise, structured intelligence brief about the x402 ecosystem — facilitator comparisons, payment flow mechanics, security concerns, micropayment pricing, or SDK guidance on Base Mainnet — and want a fast, queryable lookup rather than building your own research pipeline.

## Known failure modes

- Query outside supported domains returns an unhelpful or empty summary
- Vague or ambiguous query may yield low-quality analysis
- Ecosystem data may lag real-time activity by some delay
- Missing required 'query' param causes schema validation error
- Network or payment failure returns 402 or timeout

## How this service works

Midax402 — x402 ecosystem intelligence: protocols, facilitators, agent commerce, and market analysis, payable on Algorand Mainnet and Base Mainnet. Non-personalized analysis of x402 ecosystem data, not financial advice.

## Output

A JSON object containing a tier label ('market_brief'), a human-readable summary of ecosystem activity (e.g. request volumes, top categories), a verdict string, the endpoint name, and a non-financial-advice disclaimer.
