# SignalDesk AI – Hertz to Gigahertz Frequency Converter

> SignalDesk AI – Hertz to Gigahertz Frequency Converter is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Converts a frequency value from hertz (Hz) to gigahertz (GHz) using IEEE-754 double precision arithmetic

## Facts

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 signaldesk-ai-hertz-to-gigahertz-frequency-converter-1c835615
```

Example prompt: Convert 2400000000 hertz to gigahertz for me — I need the exact GHz value with IEEE-754 double precision.

## When to prefer this

Use this endpoint when you need a fast, programmatic, precision-guaranteed conversion of a single hertz value to gigahertz — particularly in signal processing, RF engineering, telecommunications, or hardware specification workflows. Prefer it over manual calculation when IEEE-754 double precision traceability matters or when integrating frequency unit normalization into an automated agent pipeline.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Negative values rejected (minimum is 0)
- Values exceeding 1e+100 rejected by schema validation
- Non-numeric input causes validation failure
- Network or Cloudflare Worker unavailability may return 5xx errors
- Payment failure via x402 protocol blocks execution

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing the original value in hertz, the converted value in gigahertz, the source unit ('hertz'), the target unit ('gigahertz'), the dimension label ('frequency'), and the precision standard used (IEEE-754 double). Example: {from:'hertz', to:'gigahertz', value:123.45, converted:1.2345e-7, dimension:'frequency', precision:'IEEE-754 double'}.
