Metis Swap API Overview

Metis is Jupiter’s low-level routing engine for developers who need CPI, custom instructions, or full transaction control. Three steps: get a quote (GET /swap/v1/quote), build a transaction (POST /swap/v1/swap), then sign and send via your own RPC.

​

We recommend using Swap API V2

The Swap API V2 unifies Ultra and Metis into a single API. Use /order for the simplest flow with managed execution, or /build if you need custom transactions (the replacement for Metis /swap-instructions).

​

Getting Started with Metis Swap API

1. Get Quote: Request for a quote which consists of the route plan, and other params such as integrator fee, slippage, etc.
2. Build Swap Transaction: Post the quote to build a swap transaction.
   • You can utilize other methods to return swap instructions or use CPI rather than the default swap transaction.
   • You can utilize other parameters such as priority fee, dynamic slippage, etc to customize the transaction.
3. Send Swap Transaction: Sign and send the swap transaction to the network via your own RPC or other methods.

Other Guides

• Adding Fees to Metis Swap API: Add custom integrator fees to the swap transaction.
• Requote with Lower Max Accounts: Requote with a lower max accounts to reduce the transaction size to fit more instructions or other use cases.
