HttpStatus.com is an API reliability platform that starts with realistic API mocking. Teams use it when real APIs are slow, missing, unstable, expensive, or hard to safely test. The platform allows you to generate mock endpoints from intent, OpenAPI, JSON, or example responses, and control every aspect of the response, including latency, errors, authentication, headers, and response variants.Once mocks are in place, you can promote them into reusable test artifacts, contract checks, automation runs, or chaos scenarios. The platform provides a suite of integrated tools:API Mocks – Create stateful mock APIs with realistic behavior.MCP Server – Connect workflows to AI assistants and MCP-compatible clients.Automation – Generate and run validation flows.Chaos – Inject failures to test resilience.Contract Testing – Validate OpenAPI specs and catch breaking changes.Shield – Assess API security posture.API Workbench – Convert cURL, OpenAPI, Postman, JSON, or URLs into durable tests.Additionally, a reference of every HTTP status code with meanings, headers, and fixes is available. With over 700 free tools and an MCP server, HttpStatus.com empowers developers, QA, and platform engineers to build reliable APIs.
