The Data score on business verification APIs

The score out of 100 is the share of companies a call gets right. We give each call a company's legal name and the two-letter code of the state the company formed in. A call gets a registered company right by finding the company under that name in that state. A call gets a made-up name right by finding no company. We set aside case, punctuation and how the suffix is spelled when we compare names. A call that fails or gives no answer counts as not right. Registered companies count for half the score. Made-up names count for the other half. A call that gets every made-up name wrong scores 0. A call that gets every registered company wrong also scores 0. Some providers ran on only part of the companies. We compare each part-run provider with the providers that ran on every company. In that comparison, we score each provider on the same companies: the ones the part-run provider ran on. A provider can't score higher by running only on easy companies. A provider that keeps a copy of the records can miss a company. The copy can also hold an old name for a company. We score a missing company or an old name as wrong, the same as for any other provider. We lower the score when we test the call on fewer companies than the benchmark has.
