## 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 claw402-macd-indicator-polygon-technical-analysis-07377cb2
```

Example prompt: Can you get me the MACD indicator for AAPL using a 12-day short window, 26-day long window, and 9-day signal window on daily candles, closing price as the series type, most recent 10 results in descending order?

## When to prefer this

Use this endpoint when you need MACD technical indicator data for a stock ticker without needing a Polygon.io API key, and you prefer micro-payment per-call billing via USDC over a subscription. Ideal for agents that need occasional technical analysis data on-demand with no registration overhead.

## Known failure modes

- Invalid or unsupported stock ticker returns empty data array
- Missing required query parameters may return error or empty response
- Expired or invalid USDC payment returns 402 Payment Required
- Unsupported timespan value results in error response
- Rate limiting or upstream Polygon.io outage may cause failures
- Malformed query parameters return code != 0 or empty data

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.

## Output

A JSON object with a code field (0 for success) and a data array containing MACD values including the MACD line, signal line, and histogram values with their corresponding timestamps, suitable for charting or algorithmic trading signals.
