Fund Filings (N-PORT)

Returns SEC Form N-PORT filings — monthly portfolio reports from registered investment companies (mutual funds, ETFs, closed-end funds). Use this when the user asks about: recent fund portfolio filings, when a specific fund family last reported, monthly cadence of fund disclosures, or to bridge from a fund trust name to the primary_doc.xml that contains full.

What it returns

One record per result. Fields (from a live response):

Identity — filer_state, filer_name, filer_cik, inc_state
Dates — period_ending, file_date, scraped_at
Provenance — filing_url, filing_id, primary_document_url
Details — sec_file_number, filing_type, is_amendment

Filters

filing_id	EDGAR accession number. Direct doc lookup, fastest.
filer_cik	Fund trust's SEC CIK (1-10 digits; we zero-pad internally).
filer_name	Case-insensitive substring against the fund trust name (e.g., 'wisdomtree', 'vanguard', 'fidelity').
period_ending	Filter to a specific reporting period — the month-end the filing covers (YYYY-MM-DD).
sec_file_number	SEC Investment Company file number, e.g., '811-21864'. Each fund trust has a stable number.
is_amendment	When set, restricts to NPORT-P/A amendments (true) or original NPORT-P (false). Default: both.
since	file_date lower bound (YYYY-MM-DD inclusive).
until	file_date upper bound (YYYY-MM-DD inclusive).
sort_by	Default: file_date (most recently filed first). period_ending sorts by the month the report covers.
sort_order	Default: desc.
limit	Maximum filings to return. Default 50, max 500.
