# RQM Validate Kinematic Dynamic Limits

> RQM Validate Kinematic Dynamic Limits is a paid API for AI agents from jobs.rqmtechnologies.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Validates whether a bounded trajectory conforms to caller-supplied maximum speed and acceleration limits, returning accept or reject.

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-kinematic-dynamic-limits-2d663641 -d '<json body>'
```

Example prompt: Check whether this 10-point robot arm trajectory stays within a maximum speed of 2.5 m/s and maximum acceleration of 1.8 m/s² — the trajectory timestamps run from 0 to 5 seconds with joint values for each step.

## When to prefer this

Use this endpoint when you need a lightweight, deterministic accept/reject verdict on a candidate robot trajectory against caller-defined kinematic bounds (speed and acceleration), particularly when the trajectory is already bounded and typed in RQM format. Prefer this over physical safety certification tools — it is a computational check, not a hardware safety guarantee.

## Known failure modes

- Trajectory has fewer than 2 points — minimum 2 required
- Trajectory exceeds 4096 points — maximum exceeded
- Timestamp out of range (must be between 0 and 86400 seconds)
- Values array has fewer than 1 or more than 12 elements per point
- maximum_speed or maximum_acceleration is zero or negative
- Malformed JSON or missing required fields
- Payment not provided or insufficient (x402 payment required)
- Idempotency key format invalid

## How this service works

Problem: Accept or reject a bounded trajectory against caller kinematic limits. Input: JSON with trajectory, maximum speed, maximum acceleration. Result: typed verdict, measured metrics, candidate only when verified. Limits: Software/model evidence only; 65536 request bytes; 5 s execution.

## Output

Returns an accept or reject decision indicating whether the submitted trajectory satisfies the caller-supplied maximum speed and maximum acceleration bounds, along with details about any limit violations found in the trajectory points.
