  Tezos is a self-amending blockchain platform that uses on-chain governance
  to upgrade its protocol without hard forks. The primary developer API surface
  is provided by TzKT, an open-source Tezos blockchain indexer built and
  maintained by the Baking Bad team. TzKT exposes a comprehensive REST API
  (https://api.tzkt.io) covering 100+ endpoints for querying blocks, accounts,
  operations, delegations, smart contracts, big maps, tokens (FA1.2/FA2/NFTs),
  staking data, baking rights, governance periods, and protocol metadata on
  the Tezos mainnet. The API supports deep filtering, deep selection, deep
  sorting, CSV exports, and historical data queries at specific block heights.
  A WebSocket API (SignalR) provides real-time subscription streams for new
  blocks and operations. The public TzKT API is freely available with no API
  key required; rate limits apply per IP via standard RateLimit headers and
  HTTP 429 responses. TzKT Pro is available for teams requiring elevated
  quotas and dedicated support. The indexer is MIT-licensed and can also be
  self-hosted against a Tezos node.
