Curve Finance DeFi API

healthy 3,251 Subscribers

Live DeFi data from Curve Finance — the dominant decentralised exchange for stablecoins and pegged assets (StableSwap AMM) — served from its public API as clean JSON, no cache. List every chain Curve runs on and the pool registries on each; pull the liquidity pools on a chain/registry with each pool's USD TVL, underlying coins and prices, amplification coefficient, virtual price and CRV gauge APY (sorted by TVL); fetch one pool's full detail by address; or read a chain's total and per-pool trading volume. Read live from Curve, nothing cached. This is Curve's own StableSwap pool, TVL and gauge layer across Ethereum and 20+ L2s — distinct from on-chain explorers, general DEX-pool feeds and price APIs: protocol-level data for the largest stablecoin AMM in DeFi.

WEMIX API

Live EVM on-chain data for WEMIX (chain id 1111) — the gaming-focused public Layer-1 built by Wemade, whose native token is WEMIX — served directly from public EVM JSON-RPC nodes with multi-node failover. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the WEMIX balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole WEMIX with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and game-economy analytics across the WEMIX ecosystem. Live keyless upstream. 5 endpoints.

Monad API

Live EVM on-chain data for Monad (chain id 143) — the high-performance, parallel-execution Layer-1 designed for thousands of transactions per second, whose native token is MON — served directly from public EVM JSON-RPC nodes with multi-node failover. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the MON balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole MON with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and analytics apps across the Monad ecosystem. Live keyless upstream. 5 endpoints.

Superposition API

Live EVM on-chain data for Superposition (chain id 55244) — an Arbitrum-Orbit DeFi Layer-3 with ETH gas and on-chain yield-bearing Super Assets — served directly from the public Superposition JSON-RPC with server-side resilience. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the ETH balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole ETH with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and DeFi analytics across the Superposition and Arbitrum-Orbit ecosystem. Live keyless upstream. 5 endpoints.

Matchain API

Live EVM on-chain data for Matchain (chain id 698) — the BNB-Chain-secured Layer-2 focused on decentralised identity and social, where gas is paid in BNB — served directly from the public Matchain JSON-RPC with server-side resilience. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the BNB balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole BNB with exact big-integer scaling.
