## 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 alpha-vantage-macd-via-locus-x402-27e21bcd -d '<json body>'
```

Example prompt: Can you get the MACD indicator for AAPL on a daily interval, using the default fast period of 12, slow period of 26, and signal period of 9 based on closing prices?

## When to prefer this

Choose this endpoint when you need MACD technical indicator data specifically, computed server-side via Alpha Vantage's standardized methodology, and you want to pay per-call in USDC via the x402 micropayment protocol without needing an Alpha Vantage API key directly. Prefer this over raw price endpoints when you want pre-computed momentum signals rather than raw OHLCV data.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty data object
- Unsupported interval string causes a validation error
- Payment failure or insufficient USDC balance prevents the request from completing
- Missing required 'symbol' field results in a bad request error
- Requesting data for a very recent intraday month with no data yet may return empty results
