Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 chromatic-dispersion-calculator-0021e8e1
```

Example prompt: What's the chromatic dispersion for a standard single-mode optical fiber with properties typical of silica glass — give me the dispersion coefficient and how the spectrum spreads?

## When to prefer this

Use this endpoint when you need to compute chromatic dispersion for optical or photonic systems and want a pay-per-call model with no API key setup. Ideal for one-off calculations in fiber optic design, photonics research, or telecommunications engineering workflows.

## Known failure modes

- Invalid or missing properties parameter returns an error
- Malformed JSON input schema causes a 400 error
- Payment not received results in 402 Payment Required response
- Properties outside supported material domain may return null or incomplete dispersion values

## How this service works

Fiber optic chromatic dispersion calculator. Computes dispersion coefficient D(λ) in ps/(nm·km), accumulated dispersion (ps/nm) over a fiber span, and dispersion slope for SMF-28, NZDSF, DSF, LEAF, DCF, and ULLSF fiber types. Optionally sweeps a wavelength range (C-band, L-band, or custom). Pure math — instant, zero API calls. Useful for optical network design, DWDM link budget, and dispersion compensation planning.

## Output

Returns chromatic dispersion values including dispersion coefficients and spectral properties for the given material or optical system, helping quantify how different wavelengths propagate at different speeds through the medium.
