## 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 twelvex-ema-exponential-moving-average-endpoint-b3888cc3
```

Example prompt: Can you get the EMA for AAPL using a 1-day interval with a 20-period time window so I can check its trend?

## When to prefer this

Use this endpoint when you need EMA technical indicator data for stocks, forex pairs, or cryptocurrencies and are comfortable with per-call micropayment pricing via x402. Prefer this over broader market data APIs when specifically needing EMA values for algorithmic trading signals, backtesting, or trend analysis. Ideal for AI agents making automated, pay-per-use financial data calls.

## Known failure modes

- Invalid or unsupported symbol returns an error response
- Unsupported interval string causes a bad request error
- Payment not completed (402) blocks access to the endpoint
- Missing required symbol path parameter results in a routing error
- Twelve Data upstream outage may cause delayed or empty responses
