Phone number check
flat-
Checks one phone number offline: normalises it to E.164, works out its country (including the twelve calling codes shared by several countries, such as +1 US/Canada/Caribbean) and validates the national number length against that country's numbering plan. Returns the tel: URI and the national dialling form. Numbering data from Google's libphonenumber. No network call and no API key, so it cannot fail because a third party is down.

https:x402: an unpaid request gets a 402 with the price and pay-to wallet. The check never pays.
