How this service works
Full-text search of SEC EDGAR filings: company, CIK, form, filing date, file name, a link to the matched document, its file type (e.g. EX-99.1) and the 8-K items. Results are in EDGAR relevance order; a total of 10,000 means at least that many. Filter by form types (e.g. 8-K,10-K) and filing dates. Results are capped at 20. US government data.
Output
Returns a list of matching SEC filing hits, each with the company name, CIK, form type (e.g. 8-K, 10-K), filing date, item codes, a direct link to the filing document on SEC.gov, and the file name. Also includes the total result count (which may be a lower bound), the query echo, and attribution to SEC EDGAR's full-text search index.
Example use cases
Due diligence on acquisition target
“Search SEC EDGAR for any 10-K or 8-K filings from the last two years that mention 'material weakness' — I'm doing due diligence on a potential acquisition and want to flag any companies with audit concerns.”
Monitoring regulatory risk phrases
“Find SEC filings that mention 'PFAS contamination' in 10-K forms filed since 2022-01-01, up to 20 results — I want to identify public companies disclosing environmental liability around that chemical.”
Tracking M&A deal announcements
“Search EDGAR for 8-K filings that mention 'definitive agreement' filed between 2024-06-01 and 2024-12-31, limit to 10 results — I'm trying to track recent M&A announcements in public markets.”
Technical details
Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/sec/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to search the full text of SEC EDGAR filings by keyword or phrase, optionally filtered by form type and date range. It is ideal for due diligence, compliance research, financial analysis, and monitoring disclosures across all publicly filed SEC documents. Prefer this over manual EDGAR browsing or CIK-based lookup when you don't know the specific company but want to find filings containing specific language.
Side effects
- Missing required 'q' parameter returns a validation error
- Invalid date format for 'from' or 'to' causes a bad request
- Limit outside 1–20 range may be rejected or clamped
- Very broad queries may return 10,000+ results with only a sample returned
- EDGAR upstream downtime causes service unavailability
- Obscure or misspelled terms may return zero hits
