## 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 gexlog-gamma-regime-classification-5a62d57c
```

Example prompt: Pull the gamma regime classifications for SPX from GEXLOG for the last 30 days — I want to see the regime label, trading signal (GO/CAUTION/WAIT), total GEX, and VIX close for each day.

## When to prefer this

Use this endpoint when you need structured, daily gamma exposure regime classifications for SPX with actionable trading signals (GO/CAUTION/WAIT). It is ideal for options traders, quant analysts, or trading agents that need to incorporate dealer gamma positioning context into their decision-making. Prefer this over generic market data APIs when the specific gamma regime label and GEX-derived signal are required inputs to a strategy or alert system.

## Known failure modes

- Invalid date format returns error — dates must be YYYY-MM-DD
- Start date after end date may return empty dataset or error
- Payment failure (402) if x402 USDC micropayment is not completed
- Limit of 0 or negative integer may return empty or error response
- Requesting future dates beyond today returns no data or empty array
- Very large date ranges combined with small limit may truncate results unexpectedly

## How this service works

A live fintech experiment in AI agent payments. WebMCP structured tools and x402 micropayments gate premium financial data. Documentation for agents and developers.

## Output

An array of daily records each containing: date, gamma regime label (e.g. Positive Gamma, Negative Gamma, Transition), trading signal enum (GO/CAUTION/WAIT), SPX closing price, total gamma exposure value, and VIX closing price — plus a total count of records returned.
