Design stricter API contracts with JSON Schema so validation failures are caught before production incidents.

Generate JSON Schema draft 2020-12 with validation constraints for API and data pipelines.
APIs break when payload assumptions stay implicit and validation is implemented ad hoc in multiple services. Teams discover contract drift too late, usually after downstream consumers fail.
Use JSON Schema AI to generate explicit schema contracts and validation rules.
Model input as a contract: required fields, strict types, enum ranges, pattern constraints, and backward-compatible optional fields. Treat schema changes as versioned product decisions, not quick patch logic.
Generate a production-ready contract in JSON Schema AI for your highest-volume endpoint and run fixture validation in CI.
