sec-api.io is a data provider, and the table below compares AIR with it on those terms. But AIR's API is a different kind of product: it returns research, not raw data. Each 8-K reaches the endpoint already read by AIR's engine, with its item numbers and AIR's materiality call, alongside the company's AIR Score™ and Discovery Gap. And AIR keeps a public track record: at each month-end it records the five widest Discovery Gaps, dated, and revisits them a month later.
