Quick Start

from sec_edgar_toolkit import SecEdgarApi

# Initialize with required User-Agent (SEC requirement)
api = SecEdgarApi(user_agent="MyCompany/1.0 (contact@example.com)")

# Find Apple by ticker
company = api.get_company_by_ticker("AAPL")
print(f"Company: {company['title']}, CIK: {company['cik_str']}")

# Get recent filings
submissions = api.get_company_submissions(company['cik_str'])
recent_filings = submissions['filings']['recent']

API Reference

Company Filings & Submissions

# Get all submissions for a company
submissions = api.get_company_submissions("0000320193")

# Filter by form type
annual_reports = api.get_company_submissions(
    "0000320193", 
    submission_type="10-K"
)

# Filter by date range
recent_filings = api.get_company_submissions(
    "0000320193",
    from_date="2023-01-01",
    to_date="2023-12-31"
)

# Get specific filing details
filing = api.get_filing("0000320193", "0000320193-23-000077")

XBRL Financial Data

# Get company facts (all XBRL data for a company)
facts = api.get_company_facts("0000320193")

# Get specific concept data (e.g., Assets over time)
assets = api.get_company_concept(
    cik="0000320193",
    taxonomy="us-gaap", 
    tag="Assets",
    unit="USD"
)

# Get market-wide frame data (aggregated across all companies)

quarterly_data = api.get_frames(
    taxonomy="us-gaap",
    tag="Assets",
    unit="USD", 
    year=2023,
    quarter=4
)
