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.
