SEC EDGAR Form N-MFP Filings

Apify Actor that downloads an official SEC Form N-MFP monthly data set ZIP and returns structured series-level money market fund report rows: NMFP_SUBMISSION + NMFP_SERIESLEVELINFO joined on accession number.

Data source index: https://www.sec.gov/data-research/sec-markets-data/dera-form-n-mfp-data-sets

ZIP paths (tried in order after resolving the filing-window slug):

• https://www.sec.gov/files/dera/data/form-n-mfp-data-sets/{YYYYMMDD}-{YYYYMMDD}_nmfp.zip
• https://www.sec.gov/files/structureddata/data/form-n-mfp-data-sets/{YYYYMMDD}-{YYYYMMDD}_nmfp.zip
• https://www.sec.gov/files/datastandardsinnovation/data/form-n-mfp-data-sets/{YYYYMMDD}-{YYYYMMDD}_nmfp.zip

Monthly ZIPs use filing-window date ranges, not simple month names (e.g. 20260810-20260908_nmfp.zip labeled "2026 August NMFP"). By default the Actor fetches the index HTML and resolves the ZIP for your month input. Optional zipSlug skips the index.

Grain: one dataset item per Form N-MFP series filing (submission already carries one series per accession; series-level assets/NAV joined). Portfolio holdings are not dumped; holdingsCount and classCount are counts only.
