# RQM Validate Reconstruction Quality

> RQM Validate Reconstruction Quality 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).

Compares a reconstructed signal channel against a reference channel using configurable quality metrics (RMSE, maximum absolute error, normalized correlation) and acceptance rules, returning a bounded pass/fail result.

## Facts

- Price: $0.005/call
- Payment: x402

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-validate-reconstruction-quality-cd25b419 -d '<json body>'
```

Example prompt: Check if my reconstructed channel 'ch-001' matches the reference — use RMSE with a maximum of 0.05 and normalized correlation with a minimum of 0.95, each channel has 512 complex I/Q samples.

## When to prefer this

Choose this endpoint when you need a bounded, deterministic pass/fail quality signal for a reconstructed waveform or I/Q channel relative to a known reference, especially to gate or feed a subsequent automated workflow step. Prefer it over manual metric computation when you need RMSE, maximum absolute error, or normalized correlation evaluated against acceptance thresholds in a single call. Do not use it when you need causal failure diagnosis, unbounded streaming evaluation, or hardware-level ground truth.

## Known failure modes

- Mismatched sample counts between reference and reconstruction channels cause validation error
- Fewer than 1 or more than 4096 samples per channel returns schema validation error
- Unsupported metric enum value triggers rejection
- More than 8 rules supplied exceeds maxItems limit
- Invalid channel_id format (must match ^[A-Za-z0-9._-]{1,64}$) causes request rejection
- Insufficient payment or missing x402 payment header returns 402 response
- Requesting hardware-truth or causal diagnosis — endpoint only supports bounded objective metrics

## How this service works

Validate Reconstruction Quality: Compare this reconstruction with the supplied reference and acceptance rules. 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 bounded, objective quality evaluation result containing computed metric values (RMSE, maximum absolute error, and/or normalized correlation) for the reconstructed channel compared to the reference, along with a pass/fail verdict for each rule based on the supplied minimum/maximum thresholds.
