## 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 api-quantoracle-dev-f0253768 -d '<json body>'
```

Example prompt: Calculate the Fibonacci retracement levels for Bitcoin using a swing low of $58,000 and a swing high of $73,000 — I need all the key levels including 23.6%, 38.2%, 50%, 61.8%, and 78.6% to find potential support zones on a pullback.

## When to prefer this

Use this endpoint when you need precise Fibonacci retracement levels for any asset class (crypto, equities, forex) given a defined swing high and low. Ideal for technical analysis workflows, trade entry/exit planning, and identifying key support/resistance zones programmatically.

## Known failure modes

- Invalid price range — high must be greater than low
- Missing required high or low price parameters
- Malformed input data types causing 400 error
- Negative or zero price values rejected
- Payment failure via x402 protocol resulting in 402 response
