Crypto Arbitrage API

healthy 3,501 Subscribers

Live crypto cross-exchange price comparison and arbitrage spread — the spot price of a coin on the major centralised exchanges at once, served straight from each exchange's public ticker. For any base coin it fetches the spot price from Binance, OKX, Bybit, KuCoin and Coinbase in parallel, returns the per-exchange price table, identifies the cheapest venue to buy and the most expensive to sell, and computes the spread between them — absolute and percentage — the headline cross-exchange arbitrage gap. Get the full price table, the best buy/sell opportunity, or the list of exchanges. Live, no key, no cache. Quotes are USDT (Binance/OKX/Bybit/KuCoin) or USD (Coinbase), within a few basis points. A price-discovery and arbitrage layer for trading, analytics and dashboard apps. Distinct from single-exchange price and OHLC APIs — this is the cross-exchange arbitrage view.

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.

The status endpoint returns the chain and network id, the latest block height and the node client version.

The status endpoint returns the chain and network id, the latest block height and the node client version.
