## 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 rqm-convert-capture-to-spectrum-f68b184d -d '<json body>'
```

Example prompt: Take my 1024 complex IQ samples captured at 10 MHz on channel 'rf-ch0' and convert them to a spectrum artifact using ortho normalization — I need the checksummed spectral result I can feed into the next processing step.

## When to prefer this

Choose this endpoint when you need a deterministic, checksummed frequency-domain artifact from a bounded complex IQ capture with a specific normalization convention (backward, ortho, or forward). It is ideal when the spectral result needs to gate or feed a downstream workflow step and integrity (via checksum) matters. Do not use it when you need hardware-level truth, causal RF diagnosis, unbounded streaming spectral data, or physical claims beyond what a bounded FFT can assert.

## Known failure modes

- Sample count out of range (must be 1–4096 samples)
- Sample rate out of range (must be > 0 and ≤ 1,000,000,000 Hz)
- Invalid channel_id format (must match ^[A-Za-z0-9._-]{1,64}$)
- Unsupported normalization value (must be backward, ortho, or forward)
- Payment insufficient or missing (x402 protocol)
- Idempotency key format violation
- Schema version mismatch

## How this service works

Convert Capture To Spectrum: Convert this bounded complex capture into a checksummed spectral artifact with declared... Use when: The caller needs a bounded objective result that can directly gate or feed its next step. Returns: strict JSON summary, checksummed artifact manifest. Boundaries: Deterministic bounded local signal processing only; no causal, hardware, physical, regulatory, safety, or...

## Output

A checksummed spectral artifact containing the frequency-domain representation of the input complex capture, with the declared normalization convention (backward, ortho, or forward) and a checksum for integrity verification — suitable for gating downstream steps or feeding into further spectral processing.
