# SushiSwap REST API Integration The SushiSwap API provides HTTP access to the SushiSwap Aggregator for **optimized token swaps**, **price discovery**, and **transaction generation**. It aggregates liquidity from multiple DEXs to determine the best execution route. --- ## Base URL ``` https://api.sushi.com ``` --- ## API Schema The **active API schema** is defined in: [references/openapi.yaml](references/openapi.yaml) Agents must **always rely on the schema contents** rather than hardcoded assumptions. --- ## How To Use 1. Load `references/openapi.yaml` 2. Discover available endpoints, parameters, and response shapes dynamically 3. Select the appropriate endpoint based on user intent and schema tags - Quotes → quote endpoints (e.g. `/quote/v7/{chainId}`) - Swap execution → swap endpoints (e.g. `/swap/v7/{chainId}`) - Prices → price endpoints (e.g. `/price/v1/{chainId}`) - Token info → token endpoints (e.g. `/token/v1/{chainId}/{tokenAddress}`) 4. Construct requests that strictly conform to the schema and include a valid `referrer` parameter for all quote and swap endpoints 5. Validate required parameters before execution --- ## Mandatory `referrer` Parameter - The `referrer` parameter **must be specified** on swap-related endpoints (e.g. `/quote` & `/swap`) - The agent or integrator **must identify themselves** using this field - `/quote` or `/swap` requests **must not be sent** without a `referrer` value - Agents must never attempt to omit, spoof, or auto-generate this value. --- ## Fee Customization The SushiSwap API supports customized integrator fees on swap-related endpoints (e.g. `/quote` & `/swap`). ### Default fee model - Swap-related requests follow an **80/20 fee split by default** - **80%** to the integrator (referrer) - **20%** to SushiSwap - This split applies unless explicitly overridden by SushiSwap ### Custom fee splits - Alternative fee splits require a **partnership** with SushiSwap - Agents and integrators should not assume custom splits are available. If users request alternative fee splits, agents should direct them to the SushiSwap team rather than attempting to modify request parameters. --- ## Error Handling - `422`: Request parameters are invalid → fix inputs - `529`: Server overloaded → retry with backoff - `500`: Internal error → retry or fail gracefully --- ## Schema Guidance For schema usage rules and update behavior, see: [references/OPENAPI.md](references/OPENAPI.md)
