  OpenX publishes NO sandbox in the usual sense — there is no test mode, no
  test-vs-live key prefix, no test data, no fixtures, no simulator values and no
  time simulation anywhere in the 964 published documentation sections (a
  full-text scan returns zero hits for "sandbox"). What it does ship is a hosted
  GraphQL console for the OpenXSelect API, plus a partner-side integration test
  path for demand partners. Both are recorded honestly below; neither is a
  self-serve test environment.

  - name: OpenXSelect API GraphQL Explorer
    kind: playground
    url: https://docs.openx.com/openxselect/oxs-api-graphql-explorer/
    endpoint_default: https://api.openx.com/oa/graphql
    features:
      - Schema tab listing every query/mutation with descriptions
      - SDL tab that views and downloads the complete schema file
      - Explorer tab that composes and runs queries/mutations against a live environment
      - Connection settings dialog for switching the target environment endpoint
    auth: >-
      Requires an x-apikey header set to a 90-day API key minted from
      OpenXSelect UI > Settings > API Keys. No anonymous or demo key is offered.
    environments: >-
      The Connection settings dialog accepts an arbitrary endpoint URL and OpenX
      warns that "all queries performed in the GraphQL explorer will impact the
      environment set in the Endpoint field" — production
      (https://api.openx.com/oa/graphql) is the documented value. OpenX does not
      publish the URL of any non-production environment.

integration_testing:
  - name: Demand partner test integration
    url: https://docs.openx.com/demand-partners/demand-test-integration/
    note: >-
      A coordinated pre-launch bid-integration test run with an OpenX Platform
      Development Manager, not a self-serve sandbox.
  - name: OpenXBuild enrichment service certification harness
    repo: https://github.com/openx/openx-enrichment-service-template
    path: certification/
    contents:
      - certification/docker-compose.yml
      - certification/k6/openrtb.js (k6 load script)
      - certification/k6/openrtb_1000.jsonl (1,000 sample OpenRTB bid requests)
    note: >-
      The closest thing OpenX publishes to test fixtures: a runnable local
      harness with a thousand real-shaped OpenRTB request samples, shipped for
      partners building an enrichment container. It tests the partner's service,
      not OpenX's API.
