Robot Frame Tree Consistency Validator
x402
Robot Frame Tree Consistency Validator is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.010074/call, status unknown (last checked 2026-10-15).
Validates a declared robot frame-parent tree for structural errors: multiple roots, missing parents, cycles, and self-links — without composing transforms or verifying coordinate values.

How this service works
Check a declared frame-parent tree for multiple roots, missing parents, cycles and self-links. Does not compose transforms or verify coordinate correctness. Offline typed metadata only. Retained-result recovery: 24 hours; minimal receipt metadata: 90 days.
Output
A structured report indicating whether the declared frame tree is consistent, listing any detected issues such as cycles (with the frames involved), missing parent references, self-links (a frame pointing to itself), and multiple root frames. Does not evaluate transform correctness or numeric coordinate values.
Example use cases
URDF frame tree pre-deployment audit
“Before I deploy my robot stack, can you validate these 20 declared frame-parent pairs for cycles or missing parents? The expected root is 'world' and all data is synthetic.”
Debugging a TF tree with multiple roots
“My robot's TF tree is behaving strangely — can you check these 15 frame declarations and tell me if there are multiple root frames or any self-links causing the issue? Expected root is 'odom', data class is synthetic.”
CI check for kinematic frame consistency
“As part of my automated pipeline, validate this set of 8 declared robot frames and parents for structural errors like cycles or missing parents — expected root is 'base_footprint', treat this as synthetic public data.”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/verify/robotics/frame-tree?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, offline structural check of a robot frame-parent declaration graph — specifically to catch topological errors (cycles, missing parents, multiple roots, self-links) without needing to evaluate transform math or coordinate correctness. Ideal for CI pipelines, pre-deployment validation, or debugging TF tree anomalies when you have typed metadata only and no live robot connection.
Side effects
- Frame array exceeds 32 items — rejected with validation error
- Missing required 'nonpersonalMetadata: true' field — request rejected
- No frames provided (empty array) — rejected
- Expected root frame not found in declared frames — flagged as error or warning
- Malformed frame objects in array — schema validation failure
- Service unavailable or timeout — no result returned
