# Intelligence Fundamentals As Of

`GET /api/intelligence/v1/fundamentals/{ticker}/as-of`

## Request

- Base URL: `https://api.xfinlab.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.xfinlab.com/api/intelligence/v1/fundamentals/{ticker}/as-of`
- Auth: none declared

Point-in-time-correct fundamentals: what was ACTUALLY KNOWN for
`ticker` as of `as_of_date` (YYYY-MM-DD), not the current/latest
value (services/point_in_time_store.py, piloted on
sec_xbrl_service.py -- 2026-09-17, direct response to backtesting
look-ahead-bias feedback on r/quant). Each returned concept reflects
only vintages that were already filed and past a small availability
buffer by that date; a restated figure that only became known later
is never leaked back into an earlier as_of_date.

Requires the ticker to have been ingested at least once via the
regular /fundamentals/{ticker} endpoint or the daily SEC XBRL
refresh job first -- this endpoint only reads accumulated
point-in-time history, it never makes a live SEC fetch (a fetch
today cannot tell you what was knowable on a past date).
