Field notes
The homepage describes a route-based API: each route has a fixed price shown before payment, and the stated charge applies only to successful calls. It also specifies a limited idempotency window—matching successful requests can be served again free for 10 minutes while their record remains in server memory. The site says it retains payment details and call timing, while request and result content is not written to disk, apart from keyword-research figures kept for 30 days.
