What it costs

Positions	This actor
1,000	$1.00
10,000	$10.00
100,000	$100.00

Plus $0.001 per run. One manager's latest report usually runs from a few dozen to a few thousand positions, so a full portfolio pull of 500 positions costs about $0.50. Following 25 managers every quarter, 100 positions each, costs about $2.50 a quarter.

Why use it

• One flat price. Compute is included, so the bill follows the number of positions and nothing else.
• Whole portfolios, even big ones. The information table is read as a stream, so a table with tens of thousands of positions fits in the smallest memory size. holdingsPerFiling returns the largest positions by value first, up to 10,000 per report.
• Dollar values you can compare. The SEC changed the form on 3 January 2023 from thousands of dollars to whole dollars. valueUsd is always in dollars, and each row shows its share of the whole portfolio.
• Follow one stock. Filter by CUSIP or by issuer name to see how a manager's position in a company looks, quarter after quarter.
• Straight from the SEC. It reads the filings on sec.gov with no key and keeps well under the SEC's request limit.

Quick start

1. Open the actor, enter a manager's CIK number such as 1067983, press Start.
2. Or paste this input:

{ "managers": ["1067983"], "quarters": 1, "holdingsPerFiling": 100, "maxItems": 100 }

3. Download the results as JSON, CSV or Excel, or read them through the API.

To find a manager's CIK number, search the manager's name on the SEC's EDGAR company search. Names and tickers also work for managers that appear in the SEC's company ticker list.

Use it from code

curl -X POST "https://api.apify.com/v2/acts/one_dollar_store~sec-13f-institutional-holdings/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"managers": ["1067983"], "holdingsPerFiling": 20, "maxItems": 20}'

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("one_dollar_store/sec-13f-institutional-holdings").call(
    run_input={"managers": ["1067983"], "holdingsPerFiling": 20, "maxItems": 20}
)
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item["reportPeriod"], item["issuerName"], item["valueUsd"], item["percentOfPortfolio"])

Use it from an AI assistant

Claude, ChatGPT, Cursor and other assistants can call this actor through Apify's MCP server. Add it with this server address:

https://mcp.apify.com?tools=one_dollar_store/sec-13f-institutional-holdings

Then ask, for example: "What are the ten largest positions in Berkshire Hathaway's latest 13F report, and what share of the portfolio is each?"

Switching from another 13F actor

Most 13F actors take a manager or CIK and a quarter. Here they are managers (a list of CIK numbers, tickers or names) and either quarters (how many recent reports) or reportPeriod (one quarter end). The core fields are managerName, reportPeriod, issuerName, cusip, valueUsd, shares and percentOfPortfolio.

Input

Field	Type	Default	What it does
managers	list of text	none	CIK numbers such as 1067983, tickers, or names. Required.
quarters	number	1	How many of the latest quarterly reports to read per manager, 1 to 40.
reportPeriod	text	none	One quarter end such as 2026-06-30. Replaces quarters.
holdingsPerFiling	number	100	Largest positions to return from each report, 1 to 10,000.
issuerContains	text	none	Only positions whose issuer name contains this text.
cusips	list of text	none	Only positions in these nine character CUSIPs.
includeAmendments	true or false	false	Also read amended reports (13F-HR/A). They can repeat positions of the same quarter.
maxItems	number	100	Total positions for the run, 10 to 10,000.

Example, Apple positions across three quarters for two managers:

{
  "managers": ["1067983", "1350694"],
  "quarters": 3,
  "cusips": ["037833100"],
  "maxItems": 100
}

issuerName, titleOfClass, cusip, figi	The security. The FIGI appears in newer reports only.
valueUsd	Value of the position in US dollars at the quarter end, as reported.

Sample results

Real rows from a test run on 20 October 2026 (Berkshire Hathaway, report for the quarter ended 30 June 2026). A few fields (CIK, accession number, form type, class, filing date, discretion and the two smaller voting fields) are left out here to keep the page short; every row has them.

Limits

• One row per position line, not per company. A manager can list the same security on several lines, for example one per sub manager or per discretion type, so one issuer can appear more than once in a report. Add the lines up for a total.
• Largest positions first. holdingsPerFiling keeps the biggest positions by value. The share of portfolio still refers to every position in the report.
• A 13F is a snapshot. It lists long positions of US listed securities at the quarter end, filed up to 45 days later. It does not show short positions, cash, bonds that are not convertible, or trades during the quarter. Managers can ask the SEC to keep some positions confidential, and those do not appear.
• Values in dollars. For reports filed from 3 January 2023 the SEC form states whole dollars, and before that thousands. The actor applies that rule by filing date and checks it against the implied price per share, so valueUsd is in dollars either way. A check that overrides the rule is written in the run log.
• Names and tickers. Names and tickers match the SEC's company ticker list, which holds listed companies and not every investment manager. If a name does not match, or matches several companies, the actor says so in the log and skips it. A CIK number always works.
• Pace. The SEC allows 10 requests a second. The actor sends at most 8 a second and names itself and its Apify page in the User-Agent, as the SEC asks.
• Table size. A table is read as a stream and the run stops reading after 600,000 positions of one report, far more than any real report holds.
• 13F-HR only. Notice reports (13F-NT) and combination reports (13F-CR) are not read, so a manager that files only those returns no rows. Filings made on paper are not included.
• As filed. Rows show what the manager reported. The SEC is the source of record, and nothing here is investment advice.
• Free plan. A run from a free Apify plan returns the first 10 results.

FAQ

How much does it cost to scrape 13F holdings? $1 per 1,000 positions with platform usage included, plus $0.001 for each run. A full pull of a 10,000 position report costs $10.

Do I pay for compute or proxy on top? No. Platform usage is included in the $1 per 1,000 price, and no proxy is needed.

Where does the data come from? From the SEC's EDGAR system: the list of each manager's filings on data.sec.gov, then the cover page and the information table XML of each 13F-HR filing on sec.gov. No key and no third party is involved.

Is it legal? The actor reads public data only, with no login. 13F filings are public records that the SEC publishes for everyone. How you use them is up to you: follow the SEC's fair access rules, the terms of any service you pass the data to, and the law where you live.

Is this an official SEC product? No. It is an independent tool and is not affiliated with or endorsed by the US Securities and Exchange Commission.

How do I find a manager's CIK number? Search the manager's name on the SEC's EDGAR company search. The number in the result, such as 0001067983 for Berkshire Hathaway, works with or without the leading zeros.

How do I see how a manager's holding of one stock changed? Set cusips to the stock's CUSIP, set quarters to how many reports you want, and read shares and valueUsd by reportPeriod.

When does a new quarter appear? Managers file a 13F-HR within 45 days of each quarter end, so the report for 30 September appears by mid November. Only filed reports can be read.

How do I follow filings every quarter? Schedule a run in the weeks after each quarter end with reportPeriod set to that quarter end, and use accession to drop filings you already have.

Do I need an Apify account? Yes. Actors run from an Apify account, and a free account is enough to start: it includes $5 of platform usage every month. You can sign up here. This is a referral link and it costs you nothing.

Is there a limit on the free plan? Yes. A run started from a free plan account delivers the first 10 results, then ends with a message and a link to the plans. Any paid plan returns everything you ask for, up to your own limit. The price per result is the same on every plan.
