How this service works
SEC EDGAR master index providing metadata for all SEC filings including form types, filing dates, and direct links to source documents. Can't find what you're looking for? POST feedback to /feedback, no charge.
Output
Returns a paginated list of SEC filing records, each including the company's CIK, ticker symbol, form type (e.g. 10-K, 10-Q, 8-K), filing date, and direct links to the source documents on SEC EDGAR. Results can be sorted and filtered by company identifiers, form type, and date ranges.
Example use cases
Annual report research for investor
“Get me the last 5 annual 10-K filings for Apple — I want to see the filing dates and links to the actual documents, sorted newest first.”
Tracking recent 8-K disclosures
“Fetch the 20 most recent 8-K filings for Amazon (ticker: AMZN) so I can see what material events they've disclosed to the SEC lately.”
IPO S-1 filing lookup
“Find all S-1 filings submitted in the last year — limit it to 50 results sorted by filing date descending — so I can track recent IPO registrations.”
Technical details
Endpoint
GEThttps://agent.massive.com/stocks/filings/vX/indexWhen to prefer
Choose this endpoint when you need to discover and index SEC filings by company (via ticker or CIK) or form type, especially when you want filterable, sortable metadata including filing dates and document links. Prefer this over direct SEC EDGAR queries when you need a clean, agent-friendly API with structured filtering and x402 micropayment support. Best for agents that need to enumerate or monitor filing activity rather than parse the full document content.
Side effects
- Invalid or unknown ticker symbol returns empty results
- Malformed CIK format causes validation error
- Requesting more than 10,000 results exceeds maximum limit and returns error
- Invalid form_type value returns no matching filings
- Date filter syntax errors return 400 bad request
- Rate limiting or payment failure returns 402 or 429 error
