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 forgemesh-photon-energy-converter-2ac219ff -d '<json body>'
```

Example prompt: What is the photon energy in joules and electron-volts for 532 nm green laser light, and what frequency does that correspond to?

## When to prefer this

Use this endpoint when you need to convert between wavelength, frequency, and photon energy with exact physical constants — ideal for optics, spectroscopy, physics simulations, or astronomy agents that need precise quantum energy calculations rather than approximate lookups.

## Known failure modes

- Missing both frequency_hz and wavelength_nm — endpoint requires at least one input
- Non-numeric string values for wavelength or frequency result in computation error
- Wavelength or frequency values of zero or negative numbers are physically invalid
- Extremely large or small values outside practical electromagnetic spectrum range may cause precision issues

## How this service works

Photon energy API: convert between electromagnetic wavelength (nm), frequency (Hz), and photon energy (joules and electron-volts) using exact physical constants (c, Planck's h). Give a wavelength or a frequency and get the full set. For optics, spectroscopy, physics, and astronomy agents.

## Output

Returns the complete set of electromagnetic properties for the given input: wavelength in nm, frequency in Hz, photon energy in joules, and photon energy in electron-volts, all computed using exact physical constants (speed of light c and Planck's constant h).
