## 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-equalize-pilot-capture-c77b5b0b -d '<json body>'
```

Example prompt: Fit a quaternion NLMS equalizer to my pilot capture: I have 2 input channels, 2 output channels, 5 filter taps, a step size of 0.1, and I'll provide the received quaternion samples, desired quaternion samples, and a boolean pilot mask — can you run the equalize pilot capture and return the learned outputs?

## When to prefer this

Choose this endpoint when you need a bounded, deterministic adaptive equalization result from known pilot symbols in a quaternion-domain signal — particularly for MIMO or multi-channel scenarios where you want to gate or directly feed a downstream computation step. Prefer this over generic DSP services when your signal representation is quaternion-valued and you need NLMS adaptation with a controllable step size and tap count. Do not use if you need real-time streaming equalization, hardware-level ground truth, causal diagnosis, or if your signal is not representable in quaternion form.

## Known failure modes

- Mismatched array lengths between received, desired, and pilot_mask cause validation errors
- input_channels or output_channels out of range (1–4) returns a schema validation error
- taps exceeding maximum of 16 or below minimum of 1 are rejected
- step_size of zero or negative value is rejected (exclusive minimum)
- epsilon of zero or negative value is rejected (exclusive minimum)
- received or desired arrays exceeding 1024 samples are rejected
- Malformed quaternion samples (missing w, x, y, z fields) cause request rejection
- Payment failure or insufficient USDC balance causes HTTP 402 error

## How this service works

Equalize Pilot Capture: Fit the bounded reference quaternion NLMS equalizer and return learned outputs. 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: Bounded deterministic reference processing only; no causal, hardware, operational, performance, classifie...

## Output

Returns the learned outputs of a bounded quaternion NLMS equalizer fitted to the supplied pilot capture, including the equalized signal samples that can be used directly to gate or feed subsequent processing steps. The result is deterministic and bounded, suitable for downstream automation.
