# ZK Agent Identity Prover MCP

> ZK Agent Identity Prover MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-16).

Processes zero-knowledge agent identity proofs via a monetized MCP node on the M2MCent network, returning a transaction hash confirming the proof settlement.

## 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 zk-agent-identity-prover-mcp-d8c568a1 -d '<json body>'
```

Example prompt: Prove my AI agent's identity using the ZK Agent Identity Prover — here's my agent identity payload: {"agentId":"agent-42","publicKey":"0xabc123","role":"executor"} — I need a transaction hash confirming the proof was settled on Base L2.

## When to prefer this

Choose this endpoint when you need cryptographic, on-chain verification of an AI agent's identity using zero-knowledge proofs and want settlement on Base L2 with gasless USDC micropayments. Prefer it over traditional auth endpoints when privacy-preserving identity attestation is required without exposing raw credentials, or when you need an immutable txHash as proof of verification for audit trails in multi-agent systems.

## Known failure modes

- Invalid or malformed data string causes processing failure with no txHash returned
- Insufficient USDC balance for the $0.25 per-call settlement fee results in payment rejection
- x402 protocol handshake failure if the client does not support the payment flow
- Network congestion on Base L2 causing delayed or failed transaction settlement
- Empty or missing 'data' field returns an error or false success flag

## 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 containing a transaction hash (txHash) of the on-chain settlement on Base L2 and a boolean success flag indicating whether the ZK identity proof was successfully processed and settled.
