/v1/insider-trading

GEThttps://secfeedapi.com/v1/insider-trading

Forms 3, 4, 5: every transaction and holding with owners, roles, prices, footnotes, 10b5-1 flag.

Parameter	Type	Description	Example
`ticker`	string	Issuer ticker. Case-insensitive.	`NVDA`
`cik`	integer	Issuer CIK. Use this instead of ticker for companies without a ticker.	`320193`
`owner`	string	Matches any part of the reporting owner block (name, CIK, title), case-insensitive substring.	`Huang`
`code`	string	One or more transaction codes, comma separated. See the code list below.	`P,S`
`minValue`	number	Minimum transaction value in dollars (shares times price).	`100000`
`startDate`	string	Earliest filing date, YYYY-MM-DD. Filters on the date the form was filed, not the trade date.	`2026-10-01`
`endDate`	string	Latest filing date, YYYY-MM-DD.	`2026-10-09`
`formType`	string	3, 4 or 5, or an amendment such as 4/A.	`4`
`table`	string	nonDerivative (common stock) or derivative (options, RSUs, warrants).	`derivative`
`from`	integer	Offset for paging. Default `0`.	`50`
`size`	integer	Rows per page, up to 200. Default `50`.	`50`

Rows are sorted by filing date, newest first, then by dollar value.
total is exact up to 10,000. Above that it reads 10000 and totalRelation is gte; narrow the query with dates to count precisely.
Market wide code filters without a ticker or date first look at the last 60 days, then the last 400, so the newest matches come back quickly.

/v1/form-144

GEThttps://secfeedapi.com/v1/form-144

Proposed sales of restricted and control securities: flat fields (seller, relationship, shares, market value, broker, sale date, past 3 months of sales).

Parameter	Type	Description	Example
`cik`	integer	CIK of the filer, which on Form 144 is usually the person selling, not the issuer.	`1870974`
`startDate`	string	Earliest filing date, YYYY-MM-DD.	`2026-10-01`
`endDate`	string	Latest filing date, YYYY-MM-DD.	`2026-10-09`
`formType`	string	144 or 144/A.	`144`
`flat.<field>`	string or number	Exact match on a flat field, or flat.<field>__gte / __lte for numeric ranges.	`flat.aggregateMarketValue__gte=1000000`
`data.<path>`	string	Exact match on any value in the original XML, by dotted path.	`data.primary_doc.formData.issuerInfo.issuerCik=0001045810`
`fields`	string	Set to flat to drop the full XML and return only the flat fields.	`flat`
`from`	integer	Offset for paging. Default `0`.	`20`
`size`	integer	Filings per page, up to 100. Default `20`.	`20`

To filter by issuer, use data.primary_doc.formData.issuerInfo.issuerCik with the 10 digit zero padded CIK, or flat.issuerName with the exact name.

How to

How do I get every insider trade at one company?

Filter by ticker (or cik) and page with from and size. Rows come newest first.

curl -H "Authorization: Bearer $SECFEED_KEY" \
  "https://secfeedapi.com/v1/insider-trading?ticker=AAPL&size=2"

How do I find what one executive traded?

Combine owner with ticker. owner matches any part of the name, so a last name is usually enough.

curl -H "Authorization: Bearer $SECFEED_KEY" \
  "https://secfeedapi.com/v1/insider-trading?owner=Huang&ticker=NVDA&size=2"

How do I see option and RSU activity only?

Set table=derivative. Those rows carry conv_price, exercise_date, expiration_date and underlying_shares.

curl -H "Authorization: Bearer $SECFEED_KEY" \
  "https://secfeedapi.com/v1/insider-trading?ticker=NVDA&table=derivative&size=2"

How do I list initial ownership statements from new insiders?

Use formType=3. Form 3 rows are usually holdings rather than trades.

curl -H "Authorization: Bearer $SECFEED_KEY" \
  "https://secfeedapi.com/v1/insider-trading?ticker=MSFT&formType=3&size=2"

How do I find gifts of stock?

Use code G. Gifts are reported at zero price, so value is usually 0.

curl -H "Authorization: Bearer $SECFEED_KEY" \
  "https://secfeedapi.com/v1/insider-trading?code=G&startDate=2026-10-01&size=2"

How do I pull a date range for one issuer by CIK?

Use cik with startDate and endDate. The dates refer to the filing date.

curl -H "Authorization: Bearer $SECFEED_KEY" \
  "https://secfeedapi.com/v1/insider-trading?cik=320193&startDate=2026-01-01&endDate=2026-06-30&size=2"

How do I get both buys and sells for a day?

Pass several codes separated by commas and set startDate and endDate to the same day.

curl -H "Authorization: Bearer $SECFEED_KEY" \
  "https://secfeedapi.com/v1/insider-trading?code=P,S&startDate=2026-10-09&endDate=2026-10-09&size=1"

How do I page past the first results?

Use from as the offset. With size=2, from=2 returns rows 3 and 4.

curl -H "Authorization: Bearer $SECFEED_KEY" \
  "https://secfeedapi.com/v1/insider-trading?ticker=TSLA&code=M&size=2&from=2"

How do I see Form 144 notices for one issuer?

Filter on the issuer CIK inside the XML. It is 10 digits with leading zeros.

curl -H "Authorization: Bearer $SECFEED_KEY" \
  "https://secfeedapi.com/v1/form-144?data.primary_doc.formData.issuerInfo.issuerCik=0001045810&fields=flat&size=1"

How do I find Form 144 notices handled by one broker?

Match flat.broker exactly, URL encoded.

curl -H "Authorization: Bearer $SECFEED_KEY" \
  "https://secfeedapi.com/v1/form-144?flat.broker=Morgan%2520Stanley%2520Smith%2520Barney%2520LLC&fields=flat&size=1"

How do I find large planned sales by share count?

Use flat.sharesToSell__gte.

curl -H "Authorization: Bearer $SECFEED_KEY" \
  "https://secfeedapi.com/v1/form-144?flat.sharesToSell__gte=100000&fields=flat&size=1"

How do I see amended Form 144 notices?

Set formType=144/A.

curl -H "Authorization: Bearer $SECFEED_KEY" \
  "https://secfeedapi.com/v1/form-144?formType=144/A&fields=flat&size=1"

Errors
