#starknet

Live market data for Paradex, the Starknet-appchain perpetuals and options DEX, with no key. List every instrument (perpetual futures, dated options and spot) with full contract specs; pull a per-market summary with mark price, 24h volume, open interest, funding rate and — for options — implied volatility and full greeks (delta, gamma, vega, theta); read the live order book; and stream recent public trades. Paradex is one of the few venues exposing on-chain options greeks over a keyless feed — ideal for derivatives dashboards and options analytics.

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.
