# List extensions
GET/accounts/{account\_id}/registrar/extensions
Returns metadata and JSON Schema documents describing the expected input structure for registration and transfer operations on each supported extension (TLD).
This endpoint uses cursor-based pagination. Results are ordered by extension name by default. To fetch the next page, pass the `cursor` value from the `result_info` object in the response as the `cursor` query parameter in your next request. An empty `cursor` string indicates there are no more pages.
Supports HTTP conditional GET via `ETag`. Include the `ETag` value from a previous response in an `If-None-Match` header to receive a `304 Not Modified` when the data has not changed.
