SDK Overview

Routing Engine SDK is a TypeScript/JavaScript client for Zert's routing API. Use it in front-end or back-end apps to discover chains/tokens/pairs, request quotes, run the swap signing flow, manage limit orders, and check transaction/system status.

The SDK talks only to Zert's backend at a fixed URL (DEFAULT_API_BASE_URL from the package; no runtime baseURL override). Pass api.apiKey so every request includes the x-api-key header. You can also set timeout, baseHeaders, and onError. It exposes a layer-based API (sdk.swap.build()) and flat methods (sdk.buildSwap()).
