QUESTIONS

Frequently asked questions

Request below with what you are building. We approve manually, and your key arrives by email. No self serve keys at launch, deliberately.
Our own scraper and extraction pipeline refresh the database continuously, and a human verified corrections ledger overrides bad scrapes permanently.
Caching starts at Pro. Redistribution requires the Scale commercial license. Canary records are embedded, so please do not test this.
User Data API access is OAuth with per user consent, read only scopes, and one click revocation. Nothing moves without the user saying so.
