The report states which of four stages the site reached: Discoverable (an agent gets in and can read what is sold), Agreeable (who, what, how much and on what terms are all knowable), Transactable (an agent can buy without a browser), and Provable (both, with the agreement record's hash in the buyer's approval of the payment). A seller may name a payment that already settled, in settlement, for Lens to read the agreement record's hash back from it. Returns a job at once; poll get_probe with its id until its state is complete, then fetch the report with get_report. The probe identifies itself as IntegraLens, honors robots.txt, and never buys, fills a form, or renders a page.",
