## 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 ik-inverse-kinematics-mcp-de6344f6 -d '<json body>'
```

Example prompt: Solve the inverse kinematics for a 6-DOF robotic arm where the end-effector needs to reach position (x=0.5, y=0.3, z=0.8) with orientation (roll=0, pitch=90, yaw=45) — give me the joint angles for each joint.

## When to prefer this

Choose this endpoint when you need to compute joint configurations from a desired end-effector pose for robotics, simulation, or 3D character animation tasks. Prefer it over forward kinematics solvers when you know the target position and need to derive the joint angles. Suitable for real-time or near-real-time IK queries where a single pose solution is needed.

## Known failure modes

- Target pose is outside the reachable workspace of the kinematic chain — returns no solution or error
- Ill-conditioned or degenerate kinematic configuration (singularity) — may return unstable or no solution
- Malformed or missing input data string — returns parsing or validation error
- Joint constraints too restrictive to allow a valid IK solution — returns infeasible error
- Ambiguous or underspecified chain configuration — returns an error or unexpected result

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns computed inverse kinematics solution including joint angles, positions, or rotation values for each joint in the kinematic chain needed to place the end-effector at the specified target pose.
