# RQM Compare Pipeline Responses

> RQM Compare Pipeline Responses 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 two Wave signal processing pipelines on a complex-valued fixture and returns a bounded pass/fail result based on caller-supplied RMSE and absolute error tolerances.

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-compare-pipeline-responses-0406cd9d -d '<json body>'
```

Example prompt: Compare these two Wave pipelines for me — the left one applies scale(2.0) then phase_rotate(0.5), and the right one applies conjugate then scale(2.0) — run them against my 10-sample complex fixture and tell me if they match within an RMSE of 0.01 and max absolute error of 0.05.

## When to prefer this

Choose this endpoint when you need a bounded, objective, numeric pass/fail verdict comparing two Wave signal processing pipelines on a specific fixture — especially in automated workflows, CI gates, or decision steps that require a deterministic result. Prefer this over phase inspection or diagnosis endpoints when you already know which pipelines to compare and just need to know if they agree within your tolerances. Do not use when you need hardware measurement truth, causal root-cause diagnosis, streaming output, or comparison of pipeline types not supported by RQM Wave.

## Known failure modes

- Fixture array is empty or exceeds 4096 items — request rejected with validation error
- Pipeline operations list is empty or exceeds 16 operations — validation error returned
- Invalid operation kind (not scale, phase_rotate, or conjugate) — schema validation failure
- RMSE or absolute error tolerance set to zero causing immediate failure on any non-identical output
- Complex value components exceed ±1e12 magnitude — rejected by schema bounds
- Unsupported physical or hardware claim requested — out of scope, endpoint not applicable
- Payment not completed via x402 protocol — request not processed

## How this service works

Compare Pipeline Responses: Compare these two supported Wave pipelines on the supplied fixture and caller tolerances. 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 local software evidence only; no physical, causal, regulatory, hardware, or perform...

## Output

Returns a bounded objective comparison result including computed RMSE and maximum absolute error between the two pipelines' outputs on the fixture, along with a pass/fail determination based on whether both metrics fall within the caller-supplied tolerances.
