## 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 defi-zk-proof-classifier-mcp-615bbc7c -d '<json body>'
```

Example prompt: Classify this DeFi ZK proof description for me: 'A zk-SNARK circuit proving solvency of a DEX liquidity pool without revealing individual balances.'

## When to prefer this

Choose this endpoint when you specifically need to classify text content related to DeFi zero-knowledge proofs and need a fast boolean determination. It is part of a monetized MCP network and suits agent workflows that require pay-per-call ZK proof classification without managing heavy on-premise models.

## Known failure modes

- Missing required `text` field returns a validation error
- Empty string input may return false status
- Ambiguous or non-DeFi text may result in status: false with no additional context
- Network or payment settlement failures via x402 may cause request to not complete
- Overly long text inputs may be truncated or rejected

## 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 JSON object with a boolean `status` field indicating whether the input text was successfully classified as a DeFi ZK proof-related input. No detailed classification label or confidence score is included in the schema.
