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 compiled PLONK circuit artifact, which may include the constraint system, proving key, verification key, and any circuit-specific metadata needed to generate or verify zero-knowledge proofs.
Example use cases
Private input verification circuit
“Build me a PLONK circuit that proves I know two private numbers whose product equals a public value, without revealing the numbers themselves. Here's the circuit spec: 'private a, private b, public c: a * b == c'.”
zkRollup transaction proof
“I need a PLONK circuit compiled for my zkRollup — can you process this transaction validity constraint data: 'sender_balance >= tx_amount AND new_balance == sender_balance - tx_amount'?”
Age credential zero-knowledge proof
“Generate a PLONK proof circuit for an age verification scheme — the data is 'private birth_year, public current_year, public min_age: current_year - birth_year >= min_age' so I can prove someone is old enough without revealing their exact age.”
Technical details
Endpoint
POSThttps://api.m2mcent.com/plonk-circuit-builder-mcp/api/process?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically build or compile PLONK-based zero-knowledge proof circuits as part of a cryptographic workflow, zkRollup pipeline, or privacy-preserving application. Prefer it over general ZK tooling when you need a hosted, pay-per-use PLONK circuit builder that integrates directly into an agentic workflow without local toolchain setup.
Side effects
- Invalid or malformed circuit data string returns a parsing or validation error
- Unsupported constraint types may cause compilation failure
- Malformed JSON input results in 400-level error
- Payment failure or insufficient USDC balance blocks the call via x402
- Overly complex circuits may exceed processing limits or time out
