Farcaster API

healthy 4,712 Subscribers

A live window into Farcaster, the decentralised social network, as an API via the public Warpcast feed. Look a user up by username or FID for their profile (followers, following, bio); pull a user's recent casts (posts) with their likes, recasts and replies; browse the channels people post in, ranked by followers, or filter them; or open a single channel. The on-chain social graph delivered as clean JSON for social, web3 and dashboard apps. Live data, no key. Distinct from Mastodon, Bluesky and other social platforms — this is Farcaster.

Degen Chain API

Live Degen Chain on-chain data via Blockscout. Degen Chain is a Farcaster-community L3 built on Arbitrum Orbit; gas and balances are in DEGEN. Network stats, gas prices, latest blocks, a block by height or hash, address detail with DEGEN balance, a transaction by hash, ERC-20 token metadata and a universal search across addresses, tokens, blocks and transactions. Real data, no key.

Internet Computer API

Live on-chain data from the Internet Computer (ICP), a blockchain that runs software as tamper-proof canisters on a network of independent subnets: the live network state (block height, running and stopped canisters, node count, number of subnets, message-execution rate), a ledger account's ICP balance and transaction count, a canister's type, controllers, name and subnet, and the subnets that shard the Internet Computer with their type, canisters, nodes and throughput.

Filecoin API

Live on-chain data from the Filecoin network (FIL), the decentralized storage blockchain where miners are storage providers that pledge real disk capacity: an address's FIL balance, actor type and message count — and, for a storage provider, its raw and quality-adjusted storage power and sector size; storage providers ranked by power with each one's capacity, blocks mined and rewards; a tipset (Filecoin's block) with its height, time, block count and messages; and the chain height, total network storage power and number of active storage providers.

Starknet API

Live on-chain data from Starknet, the Ethereum Layer 2 zk-rollup built on the Cairo VM and STARK proofs, via a public Starknet JSON-RPC node. Starknet has no externally-owned accounts: every account is a smart contract with native account abstraction, and fees are paid in STRK or ETH. Resolve an address's transaction nonce, the account contract class it runs and its STRK and ETH balances, read straight from the fee-token contracts. Get a block's number, hash, status, timestamp, sequencer and transaction count. Look up any transaction with its type, finality and execution status, the address that sent it and the actual fee paid. Read the live chain state — the chain id, the JSON-RPC spec version, the latest block and whether the node is syncing. Live, no key, nothing stored. Distinct from the XRP Ledger, Stellar, TRON, Aptos, Algorand, Tezos, Cardano, Hedera, Kaspa, Cosmos, Sui, NEAR, MultiversX, Solana and EVM on-chain APIs and from price feeds — this is Starknet's Cairo-account state, balances, blocks and transactions. Perfect for wallets, explorers and analytics apps.
