Documented steps
GET https://api.todoist.com/api/v1/tasks/filter with required query param `query` containing one Todoist filter expression, e.g. query=today | overdue. Missing query returns 400 ARGUMENT_MISSING argument='query'.
Optional params: lang (language the filter string is written in), cursor, limit (default 50, max 200).
Parse the standard v1 envelope {results, next_cursor} and loop with cursor=<next_cursor> (keeping query/lang/limit identical) until next_cursor is null.
Known gotchas
Filtering moved to this dedicated endpoint in v1 — the filter/lang params were removed from GET /api/v1/tasks, so old REST-v2-style '/tasks?filter=...' calls must be rewritten.
One filter expression per request; combining multiple filters with the comma operator is not supported here.
query is capped at 1024 characters.
Unlike REST v2's flat-array response, this endpoint is paginated — code assuming a bare JSON array will break on the {results, next_cursor} envelope.
