insider-trades-api 0.1.0

Official Python SDK for the Insider Trades API — real-time SEC Form 3, 4, and 5 insider transaction data.

Insider Trades API — Python SDK

Official Python SDK for the Insider Trades API — real-time SEC Form 3, 4, and 5 insider transaction data.

Installation

pip install insider-trades-api

Requires Python 3.8+. No runtime dependencies.

Quick Start

import os
from insider_trades_api import InsiderTradesAPI

client = InsiderTradesAPI(api_key=os.environ["INSIDER_TRADES_API_KEY"])

# Get recent insider purchases for Apple
result = client.get_insider_transactions(
    issuer_ticker="AAPL",
    transaction_types="purchase",
    limit=10,
)

for tx in result["insiderTransactions"]:
    owner = tx.get("reportingOwnerInformation", {})
    print(owner.get("name"), tx.get("purchaseAmount"))

If you omit api_key, the client reads INSIDER_TRADES_API_KEY from the environment.

Get your API key at insidertrades.us.

Usage examples

Recent Form 4 purchases by date range

result = client.get_insider_transactions(
    transaction_types="purchase",
    form_types="4",
    filing_date_in_est_start_date="2026-05-01",
    filing_date_in_est_end_date="2026-05-31",
    limit=50,
)

High-value transactions over $1M

result = client.get_insider_transactions(
    min_total_amount=1_000_000,
    transaction_types="purchase",
    filing_date_in_est_start_date="2026-05-01",
    filing_date_in_est_end_date="2026-05-31",
    limit=25,
)

All transactions by a specific insider

result = client.get_insider_transactions(reporting_owner_cik="1214128", limit=20)

CEO transactions across all companies

result = client.get_insider_transactions(
    officer_titles=["CEO"],
    form_types="4",
    filing_date_in_est_start_date="2026-05-01",
    filing_date_in_est_end_date="2026-05-31",
    limit=20,
)

Look up a specific filing

result = client.get_insider_transactions(accession_number="0001140361-26-023363")

Typing

The package ships with type hints (py.typed). Responses are plain dicts; TypedDict definitions describe their shape for editors and type checkers.

from insider_trades_api import (
    InsiderTransaction,
    InsiderTransactionsResponse,
    IssuerInformation,
    ReportingOwnerInformation,
    NonDerivativeTransaction,
    DerivativeTransaction,
    NonDerivativeHolding,
    DerivativeHolding,
    Footnote,
    OwnerSignature,
)

Note: the has* flags (hasPurchases, hasSales, …) are returned as the string "true", not a Python bool. Use truthiness checks (if tx.get("hasPurchases"):) rather than == True.

---

Error handling

Client-side validation failures raise ValueError before any network call. Non-success HTTP responses raise InsiderTradesAPIError, which carries the HTTP status.

from insider_trades_api import InsiderTradesAPI, InsiderTradesAPIError

try:
    result = client.get_insider_transactions(issuer_ticker="AAPL")
except InsiderTradesAPIError as err:
    print(err.status, err)  # e.g. 403 "InsiderTrades API error 403: Forbidden"

Status	Meaning
400	Invalid parameters (bad date format, invalid CIK, inverted date range)
403	Invalid or missing API key, or requested date range exceeds plan limit
429	Rate limit exceeded — retried automatically up to 3 times with backoff
504	Request timed out — retried automatically up to 3 times
500	Server error

The SDK validates date format (YYYY-MM-DD), numeric CIK, and date range order before making any network request, so many errors are caught immediately without a round trip.
