By aggregating swap quotes across various bridges, it enables users to compare rates and identify the most favorable trading option. The response includes detailed information such as the Bridge name and identifier, the input amount, the swap path, and the resulting output amounts from each bridge, making it a valuable tool for pricing data and swap execution decisions. > 💡 **Compute Unit Value:** `85` (Fixed) # OpenAPI definition ```json { "openapi": "3.0.0", "info": { "contact": { "name": "Blockdaemon", "email": "info@blockdaemon.com" }, "description": "The Blockdaemon DeFi API provides a single interface to a multitude of DeFi projects and blockchains", "title": "Blockdaemon DeFi API", "version": "1.0.0", "x-logo": { "altText": "Blockdaemon logo", "backgroundColor": "#fafafa", "url": "https://storage.googleapis.com/blockdaemon-app-static-images/marketing/PNG/dark-logo.png" } }, "externalDocs": { "description": "Blockdaemon DeFi documentation", "url": "http://www.blockdaemon.com/api/defi" }, "servers": [ { "url": "https://svc.blockdaemon.com" } ], "components": { "securitySchemes": { "ApiKeyAuth": { "type": "apiKey", "in": "header", "name": "X-API-Key", "description": "`X-API-Key: ` header must be set to authenticate API requests.You can create tokens in the \"Configure\" tab of your API access area at https://app.blockdaemon.com." } } }, "tags": [ { "name": "bridge", "description": "API endpoints for operations related to bridges" } ], "security": [ { "ApiKeyAuth": [] } ], "paths": { "/defi/v1/bridge/quotes": { "get": { "tags": [ "bridge" ], "summary": "Get Bridge Swap Quotes", "description": "Retrieves a comprehensive list of swap quotations from multiple bridges for a specified token pair pool.
