RapidTools

One API for deterministic JSON Schema validation across services and AI pipelines. Signed proof that validation happened.

Built for teams dealing with

Schema drift between microservices
Validation logic duplicated across languages
LLM outputs that need structural checks before execution
Audit requirements with no proof that validation actually ran
Retries that produce inconsistent or duplicate results

Validate API

API

Send a JSON Schema and payload, get back a signed validation result. Same inputs always produce the same output. Docs, curl example, and OpenAPI 3.1 spec included.

When NOT to use this

Your validation needs language-specific functions or custom code beyond JSON Schema
You need sub-millisecond inline validation on a latency-sensitive hot path
You're validating streaming data where buffering a full payload isn't practical
A local library (Ajv, jsonschema) already works and you don't need signed proof
You just need true/false — no attestation, no audit trail
Your schemas change faster than your deployment cycle
