Naos Trade API lets you swap any token to any token and bridge native tokens across 15 blockchains with a single integration. Get quotes, sign transactions client-side, and execute on-chain — all through a simple REST API.

​
How it works

1

Get a quote

Call GET /api/v2/quote (swap) or GET /api/v1/bridge/quote (bridge) with your parameters. The API returns an unsigned transaction with price data and routing info.
2

Sign the transaction

Sign the returned transaction client-side using ethers.js (EVM) or @solana/web3.js (Solana). Your private key never leaves your application.
3

Execute on-chain

Send the signed transaction to POST /api/v2/execute (swap) or POST /api/v1/bridge/execute (bridge). The API broadcasts it, waits for confirmation, and returns the result.

​
Key features

Universal Routing

Swap any token to any token — not just native pairs. USDC to USDT, Token to USDC, or any combination with automatic optimal path finding via the Naos Trading Router.

Cross-Chain Bridge

Bridge native tokens between any supported chain. EVM to EVM, EVM to Solana, Solana to EVM — with a 0.25% fee.

MEV Protection

Built-in sandwich attack prevention with private mempool routing on EVM chains.

Token Intelligence

Get token metadata, pool info, buy/sell taxes, liquidity depth, market cap, and contract security audits — all in one call.
