A GitHub App that checks OpenAPI 3.x JSON or YAML contracts on every pull request and posts a native GitHub Check. It catches removed endpoints, responses, required inputs, and incompatible schema changes before merge—without adding a workflow file. Founding Starter offer: £1 for the first month, then £19/month.
