Tezos Bigmaps API
Read Tezos's on-chain key-value storage (bigmaps) live from the public TzKT indexer — no key. A bigmap is Tezos's lazily-deserialised on-chain map: the data structure smart contracts use for the big stuff — token ledgers (who owns what), NFT ownership, allowances and metadata. The Tezos contract explorer lists contracts and their interface, but it cannot browse the bigmaps themselves, read a bigmap's typed key/value schema, or page through its live key-value entries. This opens that. Browse and rank the bigmaps by size with their pointer, owning contract, path (e.g. "ledger"), tags and total/active key counts; read one bigmap's detail and its typed key/value schema (what shape each row's key and value take, e.g. an address-to-nat token ledger); and page through a bigmap's live key-value entries — the actual on-chain data, such as the address-to-balance rows of a token ledger or the owner rows of an NFT collection. The storage / data layer for Tezos explorers, indexers, token dashboards and analytics. Distinct from the Tezos on-chain reader (account state), the smart-contract explorer, the FA-token registry and the .tez naming reader. Live from the indexer; short cache only.
