Frequently Asked Questions

Everything you need to know about the Finsider SEC API — supported filings, data freshness, authentication, and pricing.

What is the Finsider SEC API?

Finsider is a developer-friendly SEC API that turns raw SEC EDGAR filings into clean, structured JSON. A single REST API gives you SEC filings, standardized financial statements, Form 4 insider transactions, 13F institutional holdings, and company entity data — without parsing XBRL or scraping EDGAR yourself.

Which SEC filings and forms does the API support?

The SEC filings API covers the major EDGAR forms, including 10-K and 10-Q financial reports, 8-K material events, Form 4 insider transactions, 13F institutional holdings, S-1 registration statements, and 20-F and 6-K foreign filings. Each form is available as a structured, queryable endpoint.

How is Finsider different from the free SEC EDGAR API?

The SEC's EDGAR system gives you raw documents and as-reported XBRL tags that still need heavy parsing. Finsider is an EDGAR API alternative that normalizes those filings: we map hundreds of XBRL tags to one canonical symbol per metric, deliver consistent JSON across companies, and add ready-made endpoints for insiders, institutions, and screening.

How do I get started and authenticate with the API?

Create a free account, generate an API key, and pass it as an x-api-key header on each request. The API documentation includes a live request builder, code examples, and an OpenAPI specification so you can call SEC filings endpoints in minutes.

How fresh is the SEC filings data?

Filings are ingested in real time and typically parsed within seconds to a few minutes of being submitted to SEC EDGAR, so insider transactions, new filings, and financial updates are available almost as soon as they are public.

Is there a free tier, and what are the rate limits?

Yes — you can start for free with limited monthly requests. Paid plans raise the limits: Lite includes 1,000 requests/month, Pro gets 10,000/month, and Enterprise has no fixed limit. You can upgrade, downgrade, or cancel at any time with no penalties.
