Find which applicant-tracking system a company's careers page runs on.

Greenhouse, Ashby, Lever and Workable all publish open job board APIs, and all of them are unusable unless you already know the company's board name. None of them publishes a directory of its customers, and none could, since no vendor knows about the others.

Use this first when you have a company name rather than a careers URL.

Every open job at one company, read from its own careers system.

Returns title, department, location, employment type, workplace type, posted date, a parsed salary range where the employer publishes one, and a verify_url pointing at the employer's own advert.

Salaries are refused rather than guessed: an hourly rate, an ambiguous currency, or bands in two currencies all yield no figure, and salary_text keeps whatever the employer actually wrote.

Open jobs across several companies at once, in one schema.

This is the thing no single applicant-tracking system can do: each vendor only knows about its own customers. Companies on different systems come back with the same field names, so they can be compared directly.

One company failing does not lose the others; each failure is reported beside the results that did work.
