## 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-time-series-financial-data-1b8f470e
```

Example prompt: Pull the last 50 daily candlestick bars for AAPL so I can run a moving average on it.

## When to prefer this

Use this endpoint when you need historical candlestick/OHLCV time series data for stocks, forex pairs, or crypto assets across a wide range of intervals (1-minute through monthly). Prefer this over snapshot/quote endpoints when you need multiple historical data points for charting, backtesting, or technical indicator computation.

## Known failure modes

- Invalid or unsupported symbol returns an error or empty response
- Unsupported interval string causes a bad request error
- outputsize parameter out of range may return partial or error response
- Payment not completed results in 402 response requiring USDC payment
- Rate limiting or quota exhaustion from underlying Twelve Data provider
