# Computer Vision ZK Proof Synthesizer MCP

> Computer Vision ZK Proof Synthesizer MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.056043/call, status unknown (last checked 2026-10-12).

Accepts a text input and returns a boolean score, ostensibly synthesizing zero-knowledge proofs for computer vision tasks via an MCP node.

## Facts

- Price: $0.056043/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-12
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/computer-vision-zk-proof-synthesizer-mcp-298061f4

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 computer-vision-zk-proof-synthesizer-mcp-298061f4 -d '<json body>'
```

Example prompt: Can you run the computer vision ZK proof synthesizer on this description: 'object detected as cat with 98% confidence' and tell me if it produces a valid proof?

## When to prefer this

Use this endpoint when you need a lightweight boolean verification of a computer vision claim or output using zero-knowledge proof synthesis, especially in workflows requiring cryptographic auditability without exposing raw model data, and when paying per-call via USDC on Base L2 is acceptable.

## Known failure modes

- Missing required 'text' field returns a validation error
- Malformed JSON body causes a 400-level error
- Payment failure via x402 protocol results in a 402 response before execution
- Empty string input may return false or an error
- Network timeout on the MCP node returns a 5xx error

## 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

A JSON object with a single boolean field 'score' indicating whether the ZK proof synthesis succeeded or the input passed validation (true/false).
