## 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 synthetic-data-purity-checker-mcp-33f00da5 -d '<json body>'
```

Example prompt: Can you check this synthetic dataset for purity and tell me if any real data has leaked into it or if there are any contamination issues? Here's the data: [paste dataset content].

## When to prefer this

Choose this endpoint when you need to verify that a synthetic dataset is free from real-data contamination, PII leakage, or quality issues before using it in ML training, sharing with partners, or publishing — particularly useful in privacy-sensitive workflows where data integrity must be confirmed programmatically.

## Known failure modes

- Empty or malformed data string returns a validation error
- Extremely large data payloads may be rejected or timeout
- Ambiguous data formats may produce low-confidence results
- Payment failure via x402 protocol returns 402 status before 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 purity assessment of the submitted synthetic data, including a purity score or quality verdict, identification of any contamination or real-data leakage, and flagged issues within the dataset.
