Suggest Topics

The /v1/suggest/topics endpoint provides autocomplete functionality for searching topics by name prefix. It is useful for building filter interfaces: the returned id can be passed directly to the topic.id parameter of the news endpoints.

To use the API, you'll require an API key. You can obtain an API key by signing up for an account on the APITube website.
