## 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-bollinger-bands-bbands-technical-indicator-0b76973c
```

Example prompt: Can you pull the Bollinger Bands for TSLA on a 1-day interval with a 20-period time window so I can see if it's near the upper or lower band?

## When to prefer this

Use this endpoint when you need Bollinger Bands specifically for stocks, forex pairs, or crypto assets and want a pay-per-call model without a subscription. Prefer this over building your own computation when you need ready-made BBands values from a trusted financial data provider (Twelve Data). Ideal for agents performing technical analysis, screening for volatility conditions, or generating trading signals on individual symbols.

## Known failure modes

- Invalid or unsupported symbol returns an error or empty result
- Unsupported interval string causes a bad request error
- Symbol not covered by Twelve Data returns no data
- Missing required symbol path parameter results in a 404 or routing error
- Payment not completed (402) blocks access to data
- Rate limit exceeded returns an error response
- Very short time_period values may produce unreliable band calculations
