For developers

Everything on this site is also available as a programming interface: fund facts, holdings, events, notices and search, each with its as-of date and a link to the original document at the regulator.

The full description of every call, in the OpenAPI format, is at /api/openapi.json. Programs can read a manifest of these calls at /api/mcp; assistants connect through the assistant server. Public data needs no key; a key from your alerts page ("More options") raises the daily limit.

Spreadsheet files

Lists can be downloaded as spreadsheet files (CSV) without a key: all closed-end funds, fund announcements of the last 90 days, and each fund's history from its own page.
