Validate agent-generated artifacts against a contract before acting on them. Three validators: JSON Schema conformance, OpenAPI response conformance, SQL syntax (per dialect). Returns a typed verdict — {valid, errors[{path, code, message, fix_hint}], latency_ms} — with HTTP 200 even when invalid: an invalid artifact is a normal outcome, not an error. Deterministic and fast (~ms, no LLM in the loop), so it's cheaper than an LLM retry and safe to run on every generation. Free tier: 500 calls/month, self-service API key. MCP stdio adapter included; plain HTTP API underneath.
