summary: >-
  Copper publishes two non-production environments — a staging/demo environment and a
  blockchain testnet environment — each with its own platform UI host and API base URL.
  Separation is by HOST, not by key prefix: there is no test-vs-live key prefix
  convention, and credentials are issued per environment in that environment's platform UI.
environments:
- name: production
  platform_url: https://platform.copper.co
  api_base_url: https://api.copper.co/platform
  description: Live environment operating on real assets.
- name: staging
  aliases:
  - demo
  platform_url: https://demo.copper.co
  api_base_url: https://api.stage.copper.co/platform
  description: >-
    Staging/demo environment, separate from production and safe for testing. Copper
    advises verifying order creation, approval and webhook delivery here before
    production deployment.
- name: testnet
  platform_url: https://testnet.copper.co
  api_base_url: https://api.testnet.copper.co/platform
  description: >-
    Blockchain testnet environment. Blockchain transactions do not affect real assets.
key_separation:
  style: per-environment-host
  test_key_prefix: null
  live_key_prefix: null
  note: >-
    Copper does not publish test/live key prefixes. API keys are created in the platform
    UI for the environment being targeted (Settings > API Keys) and the environment is
    selected by base URL.
test_values:
  published: false
  note: >-
    Copper publishes no magic test values — no test card numbers, test addresses, test
    IBANs or seeded fixture identifiers. Testing is done against real testnet blockchains
    and staging portfolios provisioned for the client. No test values have been invented here.
test_clock:
  supported: false
  note: No time-simulation or test-clock facility is documented.
tooling:
- name: Postman collection
  url: https://developer.copper.co/api-reference/try-it-out#postman-collection
  download: https://developer.copper.co/copper-postman-collection.json
  description: >-
    Official Postman collection generated from the OpenAPI spec. Ships a pre-request
    script that computes the HMAC-SHA256 X-Signature automatically; set copperApiKey and
    copperApiSecret as variables. Also carries a baseUrl variable so the collection can be
    pointed at staging or testnet.
- name: OpenAPI specification
  url: https://developer.copper.co/api-reference/try-it-out#openapi-specification
  download: https://developer.copper.co/copper-open-api-public.json
  description: Downloadable OpenAPI 3.1 document, also rendered as an interactive API reference.
- name: Developer portal AI assistant
  url: https://developer.copper.co/
  description: In-docs assistant (Cmd+I / Ctrl+I) for querying the documentation.
onboarding:
  self_serve: false
  note: >-
    Sandbox access is not self-serve. Copper is an institutional provider: existing clients
    contact their relationship manager, and prospects email hello@copper.co to book a demo.
    There is no public sign-up flow that yields API credentials.
