Each Domain contains potentially 4 Arrays related to the Domain these are as follows: - models - the list of models associated with the Domain - filterConfigs - the list of filterConfigs associated with the Domain - domainMetadata - the list of Domain specific options that have been configured for this domain. ## OpenAPI ````yaml /api-reference/openapi-bundled.yaml get /v3/domains openapi: 3.0.3 info: title: LILT API description: > LILT API Support: https://lilt.atlassian.net/servicedesk/customer/portals The LILT API enables programmatic access to the full-range of LILT backend services including: * Training of and translating with interactive, adaptive machine translation * Large-scale translation memory * The Lexicon (a large-scale termbase) * Programmatic control of the LILT CAT environment * Translation memory synchronization Requests and responses are in JSON format. The REST API only responds to HTTPS / SSL requests. The base url for this REST API is `https://api.lilt.com/`. ## Authentication Requests are authenticated via API key, which requires the Business plan. Requests are authenticated using [HTTP Basic Auth](https://en.wikipedia.org/wiki/Basic_access_authentication). Add your API key as both the `username` and `password`. For development, you may also pass the API key via the `key` query parameter. This is less secure than HTTP Basic Auth, and is not recommended for production use. ## Quotas Our services have a general quota of 4000 requests per minute. Should you hit the maximum requests per minute, you will need to wait 60 seconds before you can send another request. version: v3.0.3 license: name: LILT Platform Terms and Conditions url: https://lilt.com/lilt-platform-terms-and-conditions servers: - url: https://api.lilt.com security: - BasicAuth: [] - ApiKeyAuth: [] paths: /v3/domains: get: tags: - Domains summary: Retrieve Domains description: > Retrieve a list of Domains associated with the Organization's API key.
