RTK Motion Robot Trajectory (RoboTarget)
x402
RTK Motion Robot Trajectory (RoboTarget) is a paid API for AI agents from api.rtkmotion.io, paid per call via x402, $15/call, status unknown (last checked 2026-10-10).
Returns 4D motion-capture trajectory data in NPZ format for a specified humanoid robot and human subject, including a signed download URL for the binary file.

How this service works
RTK Motion — 4D motion-capture data and AI agents for robotics and human-movement intelligence.
Output
Returns JSON metadata including: frames-per-second (60), byte size, robot model used, domain label, NPZ format descriptor, lesson path, SHA256 hash, subject ID, a time-limited download URL (expires in 900 seconds), compatible platforms (MoveIt, ROS, Isaac), ECDSA provenance signature and signer address, and robot spec (DOF, class, vendor, body/hand DOF breakdown). The binary NPZ trajectory file itself must be fetched separately via the download_url before expiry.
Example use cases
Humanoid robot grappling motion training
“Get me the BJJ Kimura-from-side-control motion trajectory from RTK Motion for the Unitree G1 robot with subject_1 — I want the NPZ file URL so I can load it into MoveIt.”
Apptronik Apollo motion dataset retrieval
“Fetch the RTK Motion trajectory data for the Apptronik Apollo robot using subject_2, and give me the download link before it expires.”
ROS pipeline motion data injection
“I need a signed NPZ motion capture trajectory from RTK Motion for the Unitree H1 robot — grab the metadata and the download URL so I can feed it into our ROS stack.”
Technical details
Endpoint
GEThttps://api.rtkmotion.io/paid/robotarget?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, cryptographically signed 4D humanoid robot motion-capture trajectories in NPZ format that are directly compatible with MoveIt, ROS, or NVIDIA Isaac. It is specifically suited for robotics pipelines that need per-robot-model (G1, H1, Apollo) retargeted trajectory data with provenance guarantees, rather than raw human biomechanics or rehabilitation data available on sibling endpoints.
Side effects
- Invalid robot value (not g1/h1/apollo) returns 400 or error payload
- Invalid subject value returns 400 or error payload
- Payment not completed or x402 flow not followed returns 402 Payment Required
- Download URL expiry (900 seconds) — expired URL returns 403 or 404
- Network timeout on binary NPZ download from signed URL
- SHA256 mismatch indicating data integrity issue on client side
