The Data score on company headcount APIs: Out of 100: the share of companies for which the call returned the number of people who work there that the company's own LinkedIn page shows, within 10%. A provider we called more than once on the same company is scored on all those calls, so no one run decides it. We lower the score when we test the call on fewer companies than the benchmark has.
