​
Overview

The /v1/mee/quote endpoint takes instructions generated from other endpoints (intent, intent-simple, build, or compose) and returns a quote with fee details and payloads to sign. Users can optionally specify a fee token to pay for gas in any of 10,000+ supported ERC-20 tokens.

​
How It Works

The quote endpoint:
  1. Accepts instructions - Takes the instruction array from previous endpoint responses
  2. Calculates fees - Determines gas costs and orchestration fees
  3. Supports fee tokens - Optional feeToken parameter enables gas payment in 10,000+ ERC-20 tokens
  4. Returns signable payloads - Provides the data that needs to be signed for execution

​
Quote Types

  • permit - EIP-712 permit signature required
  • onchain - Direct on-chain transaction
  • simple - Simple message signature

​
Workflow

  1. Generate instructions using intent, intent-simple, build, or compose endpoints
  2. Pass instructions to the quote endpoint
  3. Optionally specify a feeToken to pay gas in ERC-20 tokens
  4. Receive quote with payloads to sign
  5. Sign the payloads and submit to the execute endpoint

​
Gas Payment Options

  • Default: If no feeToken specified, sponsorship will be used
  • ERC-20 Payment: Specify any of 10,000+ supported tokens as feeToken
  • Native Token: Use zero address (0x0000...0000) for native token payment
