# Humanoid Balance MCP

> Humanoid Balance MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.35/call, status unknown (last checked 2026-10-20).

Processes humanoid robot balance-related data for motion planning, stability analysis, or posture control via an agentic MCP endpoint.

## Facts

- Endpoint: POST https://api.m2mcent.com/humanoid-balance-mcp/api/process?utm_source=zero.xyz
- Price: $0.35/call
- Payment: x402
- Status: unknown

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 humanoid-balance-mcp-02b65de7 -d '<json body>'
```

Example prompt: Analyze the balance data for our humanoid robot — here's the current state reading: '{"joint_angles":[0.1,0.05,-0.2],"com_position":[0.0,0.0,0.85],"velocity":[0.01,-0.02,0.0]}'. Tell me if the posture is stable and what corrective actions are recommended.

## When to prefer this

Choose this endpoint when you need to compute or assess balance and stability metrics for a humanoid or bipedal robot, particularly in agentic pipelines where balance analysis must be integrated as a service call. Best suited for robotics applications requiring real-time or near-real-time balance feedback without hosting your own balance computation stack.

## Known failure modes

- Malformed or empty data string returns a parsing error
- Data outside expected sensor ranges may yield unreliable stability scores
- Missing required balance fields in the data payload may cause computation failure
- Network timeout on large or complex data inputs
- Payment failure via x402 protocol blocks request processing

## 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 a processed assessment of the humanoid robot's balance state, likely including stability scores, risk indicators, and recommended corrective actions or control outputs based on the submitted data string.
