3,240 Subscribers
The Liquid Network — Bitcoin's confidential sidechain — live from the public Blockstream esplora API, no key, nothing cached. Liquid is a federated Bitcoin sidechain with one-minute blocks, confidential transactions and issued assets (Tether's USDt and many others live here as Liquid assets), with L-BTC pegged one-to-one to Bitcoin. This is the first Liquid reader in the marketplace. Read the live network status — the chain tip block height and the current mempool, with the count of unconfirmed transactions, their total virtual size and total fees. Read any block by height, or the current tip, with its hash, previous block, timestamp, transaction count, size and weight. And read the live fee estimates in sat/vB keyed by the number of blocks you are willing to wait. The on-chain layer for Liquid wallets, asset issuers, explorers and analytics. Live from blockstream.info.

Cardano Native Token Registry API
Cardano native tokens, live from the public Koios API — no key, nothing cached. On Cardano every token is a "native asset" identified by a policy id plus an asset name, minted under a Plutus or native minting policy. The Cardano on-chain reader lists the tokens held by an account, but there is no token registry in the marketplace; this opens it. Browse the verified token registry — the curated tokens that have submitted off-chain metadata, with their ticker, decimals, description and logo. Look up a single token in full with its on-chain facts: the asset fingerprint, total supply, how many times it has been minted and burned, and when it was first created. And list every native asset minted under a given policy id — one policy can mint a single fungible token or a whole NFT collection. The token layer for Cardano wallets, DEXs, token explorers and analytics. Live from api.koios.rest.

Algorand ASA Token Registry API
Algorand Standard Assets (ASAs) — Algorand's native token standard — live from the public Algonode indexer, no key, nothing cached. Every fungible and non-fungible token on Algorand, including Circle's USDC and Tether's USDt, is an ASA. The Algorand on-chain reader looks up a single asset, but there is no ASA registry in the marketplace; this opens it. Browse the ASA space paginated, each asset with its id, name, unit, total supply and decimals. Look up a single ASA in full — its name, unit, total supply (raw and decimal-adjusted), project URL and the on-chain role addresses that govern it: the manager (can reconfigure or destroy), the reserve, the freeze address and the clawback address. And search ASAs by name to find a token (with a reminder to verify the creator, since anyone can mint an ASA with any name). The token layer for Algorand wallets, DEXs, token explorers and analytics. Live from mainnet-idx.algonode.cloud.
