Use Otto’s SEC filings APIs to turn a US-listed company ticker into structured financial statements, a fundamentals report or insider-filing records with EDGAR links. Choose the filing type first: a Form 4 reports transactions, while a Form 144 is a notice of a proposed sale and does not establish that it happened.

​
Choose the result you need

All four routes below use GET with a required ticker query parameter, such as NVDA or AAPL. Each route link opens its free request reference and indicative price; the live payment challenge supplies the amount for your call. For a manager’s reported portfolio, cross-issuer filing activity or beneficial-ownership filing events, use the endpoint selector in SEC methodology. These are different questions from a company’s fundamentals or its insiders’ transactions.

​
Prepare a request

Inspect the current input contract for your chosen route:
Then request its price challenge with the same inputs you intend to buy:
This unpaid request returns a 402 challenge, not financial statements. Follow HTTP API to approve a bounded payment and send the paid request. Use API schemas and examples to inspect the route’s declared output before paying; a discovery example is not current company data.

​
Read the delivered data

Data endpoints return their result in data and snapshot information in meta. Keep both, together with the original request and receipt. The equity report-card guide explains TTM reconstruction and one-time-item adjustments. For model-building, use the financial-statement cells and their provenance; generated narrative is a separate interpretation.

​
Freshness, amendments and coverage

SEC EDGAR is the source of record. Otto supplies parsing, validation and cached snapshots; filing dates and financial periods can be much older than the response’s generatedAt. Read meta for snapshot age and degradation, then inspect the dates in the filings themselves. A first request can take longer when the ticker has no recent snapshot.
  • Missing financial values are null, not zero. A fund without issuer XBRL or a non-USD-only filer can return statementsAvailable: false and a reason while retaining its filing index.
  • Form 4 codes P and S cover purchases and sales, including private transactions. Awards, gifts and option exercises are separate codes. The filing does not establish motive.
  • A detected Form 4 amendment withholds the affected window; detection can lag the filing. Form 144 amendments instead withhold aggregate unit/value totals while individual notices remain visible.
  • A Form 144 value is the filer’s estimate at notice time. An empty notices list can be a valid result for the disclosed lookback. Form 4 has a different availability rule; do not generalize empty-result behavior across routes.
  • A capped filing window is not an exhaustive historical feed. Check coverage before comparing companies or reporting a total.
