# RQM Gate Signal Capture

> RQM Gate Signal Capture is a paid API for AI agents from jobs.rqmtechnologies.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Applies caller-supplied metric rules to a bounded scalar, multichannel, or I/Q signal capture and returns pass/fail gate results with all measurements and rule violations.

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-gate-signal-capture-6247cdb7 -d '<json body>'
```

Example prompt: Check this 1 kHz single-channel signal capture against my rules — rule 'rms-check' on channel 'ch0' must have RMS between 0.1 and 0.9, and rule 'freq-check' must have dominant frequency between 900 and 1100 Hz — tell me if it passes or fails and show all measurements.

## When to prefer this

Use this endpoint when you need a deterministic, bounded pass/fail gate on signal metric data — such as gating a pipeline step on signal quality, verifying a test fixture result, or enforcing compliance bounds on captured waveforms. Prefer it over diagnostic endpoints (like RQM Diagnose Multichannel Capture) when you need a binary accept/reject decision rather than causal diagnosis. Do not use it when you need hardware truth, an unbounded streaming analysis, or when you lack sampled signal data.

## Known failure modes

- Fewer than 16 or more than 1024 samples per channel causes rejection
- More than 8 channels or more than 32 rules causes validation error
- channel_id or rule_id patterns not matching [A-Za-z0-9._-] cause schema rejection
- Sample rate outside (0, 1e9] Hz rejected
- Referencing a channel_id in a rule that does not exist in channels array
- Mismatched signal_kind and channel roles (e.g. IQ kind without i/q role channels)
- Insufficient USDC balance or max_total_price too low causes payment rejection

## How this service works

Problem: Accept or reject this bounded signal capture against the caller-supplied metric rules and return every measurement and violation. Input: JSON with sample rate hz, channels, rules. Result: measurements, violations and checksummed artifacts. Limits: Bounded signal processing only; 8 channels; 1024 samples/channel.

## Output

Returns a structured gate result indicating overall accept or reject, per-rule metric measurements (e.g. RMS, dominant frequency, sample count, peak-to-peak), and a list of any rule violations including which rule was violated, the measured value, and the configured bounds.
