**Documentation:** https://json-schema.org

JSON Schema is one of 15 APIs that [Agent Readiness](https://apis.io/providers/agent-readiness/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Schema, Validation, Agent Readiness, and Standards. The published artifact set on APIs.io includes API documentation and a GitHub repository.

The vocabulary that lets an agent validate request and response bodies against typed contracts. Published JSON Schemas (independent of, or embedded in, an OpenAPI) are a strong agent-readiness signal because they let agents self-correct payloads before sending.
