How this service works
A bounded head of ONE table in a Form 13F data set, read with two byte-range requests against sec.gov (the archive's central directory plus the first 256 KB of the chosen table) so the multi-hundred-MB zip is never downloaded. Returns the archive's members with sizes, the table's columns and its first rows (1-200, default 25) as objects: SUMMARYPAGE (per filing: holdings count, total value, confidential-omission flag), SUBMISSION (accession, filer CIK, period, form), COVERPAGE (manager name and.
Output
Returns a JSON object containing sampled rows from the requested 13F table, column names, the source ZIP URL, dataset metadata (ID, date range, size in MB), archive member details, and flags indicating whether the result is partial and how many rows were returned.
Example use cases
Inspect latest 13F summary data
“Show me the first 25 rows of the SUMMARYPAGE table from the latest SEC 13F dataset — I want to see the total table entry counts and portfolio values.”
Preview a specific quarter's holdings
“Fetch the first 100 rows of the INFOTABLE from the 2024q4 EDGAR 13F dataset so I can see what institutional positions were reported that quarter.”
Explore 13F dataset structure before analysis
“Give me the first 10 rows of the COVERPAGE table from the 01jun2026-31aug2026 13F dataset — I need to understand the column names before I start analyzing it.”
Technical details
Endpoint
GEThttps://agent402.tools/api/edgar-13f-dataset-head?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick preview or structural sample of SEC EDGAR Form 13F institutional holdings data without downloading the full dataset ZIP. It's ideal for exploring table schemas, validating column names, or sampling a small number of rows for analysis before committing to a full data pull. Prefer this over direct SEC file downloads when you need fast, structured JSON output without handling ZIP extraction yourself.
Side effects
- Invalid table name returns an error — only SUBMISSION, COVERPAGE, OTHERMANAGER, OTHERMANAGER2, SIGNATURE, SUMMARYPAGE, or INFOTABLE are accepted
- Invalid dataset ID (not matching any available quarter) returns an error
- rows parameter outside 1-200 range may be rejected or clamped
- Dataset not yet published for a future quarter returns an empty or error response
- Network timeout if the source SEC ZIP file is very large or temporarily unavailable
