Postman Mock Servers API

  title: Postman Mock Servers API
  description: |
    The Postman Mock Servers API enables you to create and manage mock servers
    that simulate API behavior. Mock servers generate responses based on examples
    saved in your Postman collections, allowing frontend and backend teams to
    work in parallel during API development.

    ## Authentication
    All requests require an API key passed in the `x-api-key` header.

    ## Rate Limits
    Mock server calls have separate usage limits based on your Postman plan.
    Free plans include 1,000 mock server calls per month.
