# RQM Extract Wave Features

> RQM Extract Wave Features is a paid API for AI agents from jobs.rqmtechnologies.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Converts complex multi-channel IQ sample captures into a deterministic, versioned Wave-Intelligence feature vector with an input digest.

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 rqm-extract-wave-features-1e1160d6 -d '<json body>'
```

Example prompt: Extract the Wave-Intelligence feature vector from this IQ capture: I have 2 channels sampled at 1000000 Hz, each with 512 complex samples (real and imaginary parts), channel IDs 'ch0' and 'ch1' — give me the versioned deterministic feature vector and input digest.

## When to prefer this

Choose this endpoint when you need a bounded, reproducible, versioned feature representation of complex IQ/waveform data that can directly gate or feed a downstream ML or decision step. Prefer it over raw spectrum conversion (RQM Convert Capture To Spectrum) when you need a compact feature vector rather than a full spectral artifact, and over open-ended analysis when you need deterministic, auditable outputs. Not suitable when you need hardware-level truth, causal RF diagnosis, streaming data, or physical claims beyond the supported feature scope.

## Known failure modes

- Invalid sample_rate_hz (zero or negative) returns validation error
- Channel samples array outside 1–1024 bounds returns schema validation failure
- Channel ID not matching pattern ^[A-Za-z0-9._-]+$ returns 422 error
- More than 8 channels submitted returns schema rejection
- Malformed complex sample objects (missing real or imaginary) returns 400
- Insufficient payment or missing x402 payment header returns 402 Payment Required
- Idempotency key format violation returns validation error

## How this service works

Extract Wave Features: Return the versioned deterministic Wave-Intelligence feature vector and input digest. 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

A versioned, deterministic Wave-Intelligence feature vector derived from the submitted complex IQ samples, along with an input digest that allows the caller to verify and reproduce the transformation. The response includes a schema version identifier and the feature vector suitable for direct downstream gating or model inference.
