  The public TzKT API (api.tzkt.io) is free and open access — no registration
  or API key is required. Rate limits are enforced per IP via standard HTTP
  headers (X-RateLimit-Limit-Second: 50, X-RateLimit-Limit-Day: 3,000,000).
  TzKT Pro is available for teams that need elevated quotas, dedicated
  infrastructure, or SLA-backed support; contact Baking Bad for commercial
  terms. Self-hosting (MIT license, Docker images on Docker Hub) is a
  cost-free alternative for teams with their own Tezos node.
