Numberbroom tools (2)

write = sends, deletes, buys or posts
  • get_credit_balanceFree

    Check the remaining pre-paid API credit balance for the connected NumberBroom account. Free to call — does not spend credits.

  • verify_phone_numberFree

    Verify a single US phone number: carrier-level line type (mobile, landline, VoIP, disconnected), carrier name, an activity score, and whether the number is a known TCPA litigator. Does not check Do Not Call registries. Costs $0.20, charged against the caller's NumberBroom API credit balance — a number that fails to parse as a phone number is not charged. Get an API key at https://numberbroom.com/settings.
