xAI has provided documentation for its Collections API, which allows for the management of collections and documents. The base URL for collection management is shared with the Management API at https://management-api.x.ai/. Authentication requires an xAI Management API Key using a Bearer token in the Authorization header.

Key Points

  • The Collections API supports managing collections and documents.
  • Authentication for the Collections API uses an xAI Management API Key.
  • The API allows filtering collections by collection_id, collection_name, created_at, and documents_count.
  • Document listings can be filtered by file metadata such as name, content_type, size_bytes, created_at, and document fields like status.
  • Pagination is supported for listing collections and documents, with a default limit of 100 items per request.
  • Collections can be sorted by collection_name by default, and documents by name by default.
  • The API includes endpoints for retrieving, updating, and deleting individual documents, as well as batch retrieval.

Context

According to xAI, the Collections API provides endpoints for detailed management of data within collections. This includes defining field constraints for documents and handling team ownership of collections and documents. The API also supports regenerating indices for specific documents.

Why It Matters

Developers working with xAI's platform can use the Collections API to programmatically organize and query their data, enabling more structured and automated content management workflows.

What To Do

  • Review the xAI Management API documentation for details on provisioning an API key.
  • Test the filtering capabilities for collections using collection_id, collection_name, created_at, and documents_count.
  • Experiment with document filtering based on status, name, content_type, size_bytes, and custom fields.{key}.
  • Note the pagination_token for handling large result sets when listing collections or documents.
