# RQM Apply Verified Phase Correction

> RQM Apply Verified Phase Correction is a paid API for AI agents from jobs.rqmtechnologies.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-16).

Applies a bounded phase rotation (in radians) to complex I/Q signal samples and verifies caller-supplied numeric preservation assertions (magnitude error and inverse round-trip MSE).

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-apply-verified-phase-correction-23ad326d -d '<json body>'
```

Example prompt: Apply a phase correction of 0.785 radians (pi/4) to my two-channel I/Q signal sampled at 1 MHz, and verify that the maximum magnitude error stays below 0.01 and the inverse round-trip MSE stays below 0.001.

## When to prefer this

Use this endpoint when you need to apply a known, bounded phase rotation to complex I/Q samples and programmatically assert that numeric preservation invariants (magnitude and MSE) hold — enabling deterministic gating of downstream pipeline steps. Prefer this over a raw phase rotation library when you need server-side assertion verification as a quality gate. Do not use when you need hardware-truth phase measurement, causal diagnosis of phase error, unbounded streaming, or diagnosis of why a phase offset exists.

## Known failure modes

- Angle out of range: angle_radians must be between -25.13 and +25.13; values outside this range are rejected
- Assertion violation: if computed magnitude error or MSE exceeds caller-supplied thresholds, the call fails with assertion details
- Too many samples: each channel supports up to 1024 samples; exceeding this limit causes a validation error
- Too many channels: maximum 2 channels per request
- Invalid channel_id: must match pattern ^[A-Za-z0-9._-]+$ with length 1–64
- Invalid sample_rate_hz: must be a positive number up to 1,000,000,000
- Payment failure: insufficient USDC or x402 payment not accepted
- Schema mismatch: missing required fields like sample_rate_hz, channels, angle_radians, or assertions

## How this service works

Apply Verified Phase Correction: Apply a caller-supplied phase correction and verify numeric preservation assertions. 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, perceptual, safety, or...

## Output

Returns the phase-corrected complex I/Q samples for each channel along with assertion verification outcomes, including computed magnitude error and inverse round-trip MSE values compared against the caller-supplied thresholds. If assertions are violated, the response indicates which assertion failed and by how much.
