DEX Pairs API

healthy 4,325 Subscribers

Live decentralised-exchange trading-pair data — no key, nothing cached. For any token or trading pair across every major chain and DEX (Ethereum, Solana, BSC, Base, Arbitrum, Polygon and dozens more, on Uniswap, Raydium, PancakeSwap and the rest) it returns the live on-DEX market: the price in USD and in the native quote token, the pool liquidity, the 24-hour volume, the fully-diluted valuation and market cap, the price change over 5 minutes, 1, 6 and 24 hours, and the count of buy and sell transactions. The search endpoint finds every pair matching a token symbol, name or address. The token endpoint returns all the pools a token trades in, ranked by liquidity, so you can find where the real liquidity is — Wrapped Ether trades in pools led by a Uniswap WETH/USDC pool with tens of millions in liquidity. The pair endpoint returns one specific pool by chain and pair address in full detail. This is the DEX market-data layer every trading, screener, wallet, sniping and portfolio app needs — real pools, real prices, every chain. Live from DexScreener, nothing stored. Distinct from aggregate DEX-volume and centralised-exchange ticker APIs — this is per-pair on-DEX data. 4 endpoints.

Sifchain API — oanor API marketplace

Sifchain API

Live on-chain data for Sifchain (chain id sifchain-1) — the Cosmos-SDK Layer-1 omni-chain decentralised exchange, whose native token is ROWAN — served directly from public LCD/REST nodes with multi-node failover. The status endpoint returns the latest block height and time, chain id, the staking bond denom and the current minting inflation rate. The validators endpoint lists the active bonded validator set ranked by stake, each with its moniker, operator address, self-plus-delegated ROWAN, commission rate and jailed flag. The supply endpoint returns the total ROWAN supply, the amount bonded in staking and the resulting bonded ratio. The governance endpoint returns the most recent on-chain proposals with their id, title, status and voting window. ROWAN uses an 18-decimal base denomination which is converted to whole ROWAN with exact big-integer scaling, and every figure is read live from the chain — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for staking dashboards, validator and delegator tooling, explorers, governance trackers and portfolio or analytics apps across the Cosmos and cross-chain DEX ecosystem. Live keyless upstream. 5 endpoints.
