Network parameters accept either network names (e.g. ETHEREUM_MAINNET) or numeric chain IDs for EVM networks (e.g. 1). Token parameters accept either asset names (e.g. USDC, ETH) or token contract addresses (e.g. 0xa0b8...). For native tokens via contract address, use the network's zero address (e.g. 0x0000000000000000000000000000000000000000 for EVM, 11111111111111111111111111111111 for Solana). ## OpenAPI ````yaml https://api.layerswap.io/swagger/v2/swagger.json get /api/v2/sources openapi: 3.0.1 info: title: Layerswap API V2 version: v2 servers: - url: https://api.layerswap.io description: Mainnet security: - X-LS-APIKEY: [] paths: /api/v2/sources: get: tags: - Swaps summary: Get Sources description: >- Retrieves all available source routes.
