Does every pair have the same start date?
No. Historical depth depends on the pair and source coverage.
Coverage
How far back does FXpeek historical exchange-rate data go?
Short answer
Coverage varies by currency pair and upstream source. Check the pair page or API response for the actual available dates; do not assume every pair starts in the same year or updates on the same schedule.

Choose the right FXpeek surface
If the pair page has dated rowsUse its first and latest available dates as the visible coverage boundary.
If a requested pair has no verified dataDo not infer or generate a thin page; request coverage instead.
If continuity mattersInspect missing dates and provider calendars before relying on row counts.

FAQ
Are future dates included?
No. FXpeek must not output rows beyond the latest available source date.
Can a pair be added on request?
Coverage requests can be reviewed, but a page should only be published after data is verified.
Reference note
Treat coverage as a pair-level fact: verify first date, latest date, missing dates, and source before using a series.
