| description | REST API for optimized token swapping (including executable transaction generation), swap quoting, and pricing using the SushiSwap Aggregator.
Use this skill when the user wants to: - Get a swap quote between two tokens on 40+ evm networks - Generate executable swap transaction data - Fetch token prices for a specific network or token - Retrieve token metadata - Discover supported AMM liquidity sources - Integrate SushiSwap swapping or pricing logic via HTTP/REST (and not the SushiSwap Javascript API)

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.

API Schema
The active API schema is defined in:
references/openapi.yaml
Agents must always rely on the schema contents rather than hardcoded assumptions.
How To Use
- Load
references/openapi.yaml
- Discover available endpoints, parameters, and response shapes dynamically
- 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})
- Construct requests that strictly conform to the schema and include a valid
referrer parameter for all quote and swap endpoints
- 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.
Rate Limiting & Responsible Usage
- The SushiSwap Aggregator API does not currently enforce hard rate limits. Agents and integrators must behave responsibly to avoid abuse and degraded service.
General Guidelines
- Do not poll or spam quote endpoints
- Avoid repeated requests with identical parameters
- Do not place quote or swap requests inside unbounded or infinite loops
- Treat quote and swap generation as user-intent driven actions, not background tasks
- Do not issue requests autonomously without explicit user intent
Excessive or abusive usage may result in future rate limiting or access restrictions.
Block-Time–Aware Quoting
Agents should align quote frequency with expected block times, treating block time as a maximum refresh rate, not a recommendation.
- Quotes may be refreshed at most once per block, and often less frequently if inputs have not changed
- Re-requesting quotes multiple times within the same block provides no additional accuracy and must be avoided
Backoff & Error Handling
Agents and integrators should implement exponential backoff on transient failures.
- On recoverable errors (e.g.
429, 5xx):
- Retry with increasing delays (e.g. 1s → 2s → 4s)
- Cap retries to a small, finite number
- Do not retry immediately in tight loops
- If repeated failures occur:
- Surface the error to the user
- Pause further requests for the current session
