#indexer

Browse the Aptos token universe live from the official public Aptos Indexer GraphQL — no key. The Aptos on-chain reader resolves a single address's state from the fullnode, but it cannot browse the fungible-asset universe, rank tokens by supply, browse NFT collections, or list who holds a token. This opens that, on top of the Indexer. Discover and rank Aptos fungible assets (the FA / coin standard) with their asset type, name, symbol, decimals, decimal-adjusted supply, token standard and creator; browse NFT collections ranked by current supply with their creator, max supply and metadata uri; and list the holders of any fungible asset with their decimal-adjusted balances, largest first. The discovery, NFT and distribution layer for Aptos wallets, token explorers, NFT marketplaces and analytics. Distinct from the Aptos on-chain reader (per-address account state), the validator reader and the Move view-function reader. Live from the indexer; short cache only.

Convert a timestamp or date into the block number that was live at that moment on any of 100+ blockchains, keyless. On-chain analysts, indexers and dashboards constantly need "what block was chain X at time T" to query historical state, and "which blocks cover this time window" to scan a period. This API answers both — for a single moment and for a date range (returning the start and end block plus the block count and average block time). Live, nothing stored. The timestamp-to-block layer for EVM and non-EVM chains alike. Backed by the open DeFiLlama coins API.
