概览

What is Schemacheck Agent?

Schemacheck Agent is a machine-native paid API that validates JSON payloads against JSON Schema. It returns structured validation results including validity, errors with JSONPath locations, a plain-English summary, and optional corrected payload suggestions. Built for autonomous agents, backend pipelines, and developers who need reliable per-call JSON validation.

How to use Schemacheck Agent?

Connect an MCP-compatible client to https://projectx402-production.up.railway.app/mcp for tool-based usage, or call the REST endpoints directly. The free trial endpoint requires no payment; the paid endpoint uses x402 v2 USDC micropayments of $0.005 per call on Base mainnet. MCP tools available are validate_schema (full, with repair) and validate_schema_trial (free, no repair).

FAQ from Schemacheck Agent

What access modes does Schemacheck Agent support?

Schemacheck Agent supports MCP tools via Streamable HTTP and REST endpoints with x402 USDC micropayments on Base mainnet.

Is there a free way to try Schemacheck Agent?

Yes, the trial endpoint at POST /v1/schema-check/trial is free but limited to 32KB request bodies and does not include repair functionality.

What is the cost per call for the paid endpoint?

Each paid call costs $0.005 USDC, processed via the x402 v2 micropayment protocol on Base mainnet.

Does Schemacheck Agent require a runtime or library installation?

No. Schemacheck Agent is a remote API — no local library or runtime dependencies are needed beyond an HTTP client or MCP-compatible agent.

What data does Schemacheck Agent return when validation fails?

The response includes an array of errors with path, error code, message, and schema path; a plain-English summary; a confidence score; and optionally a suggested corrected payload.
