SEC.gov (EDGAR)
sec.gov
Editor’s pick Hands-on review
The official source of U.S. regulatory filings. EDGAR provides free public access through its web portal, JSON data APIs, and structured RSS feeds (updated every 10 minutes). Developers can use the APIs on data.sec.gov for submissions and XBRL datasets, while filers use separate EDGAR Next APIs that require tokens. No email alerting is provided—RSS is the only push channel. Automated access must respect fair-use guidelines, including a descriptive User-Agent.

Wayback Machine (Internet Archive)
web.archive.org
General‑purpose web archiving used widely in financial research to cite and compare historical webpages (IR pages, fund fact sheets, product sites). Save Page Now (SPN2) enables on‑demand snapshots with options like outlink capture and full‑page screenshots. Availability and CDX APIs expose snapshot discovery; Memento provides time‑based negotiation. Rate limits/quotas apply to SPN2; crawling and replay behavior may vary by target site robots/policies. Some large platforms (e.g., Reddit) restrict Wayback access to content.
