note: 'Vonage publishes no single rate-limit page (developer.vonage.com/en/getting-started/concepts/rate-limits
  returns 404); the limits are spread across support-center articles, one per product, so each row carries its own
  source: URL and limit_text is verbatim from THAT page. The top-level source is the SMS throughput article; rows
  quoted from other articles will not be found on it by a single-page checker.'
