Layoffs are a leading indicator. Read them before earnings.
WARN Act filings are a legally required, public early warning that a company is cutting headcount, often weeks before it shows up in a print or a guidance cut. CanaryWhistle turns that scattered, fifty-state paperwork into one clean, queryable feed.
The signal exists in public records, but it is spread across dozens of state labor department pages in inconsistent formats, with no history and no API. By the time it reaches a headline, the edge is gone. We collect it the day it is filed, normalise it, and add role-level detail and an estimate of the payroll coming off the books.
Every filing on record for an employer, with affected headcount and locations, via a single endpoint.
A trend index showing which industries and states are accelerating on a rolling 90-day window.
Each record carries an estimate of jobs cut and annual payroll leaving the market, derived from public BLS wage medians.
