  Blockchair offers a free tier for personal use and testing (no key required up
  to 1440 requests per day, roughly one request per minute on average) and paid
  Enterprise API plans metered by calls per day, billed monthly. All plans grant
  access to every featured blockchain. Custom plans with unlimited requests,
  dedicated infrastructure, or specialized support are available on request.
  Each API call also carries an internal request-cost weighting, where heavier
  queries consume more of the daily call budget.
notes: >-
  Prices and daily-call thresholds are as published on the Blockchair API plans
  page; verify current rates against blockchair.com/api/plans during
  reconciliation. Payments are processed via PayPal.
