​
Overview

The QuoteIntent endpoint allows you to request a quote for a cross-chain intent transaction. It provides comprehensive information about the transaction including gas fees, optimal routing, and price impact.

​
Use Cases

  • Get a quote for swapping tokens across different chains
  • Estimate fees before executing a cross-chain transaction
  • Compare different routing options
  • Calculate price impact and slippage

​
Request Parameters

​
Required Fields

  • ownerAddress (string): The wallet address initiating the transaction
  • originChainId (number): Source chain ID where the transaction originates
  • originTokenAddress (string): Contract address of the source token
  • destinationChainId (number): Target chain ID for the transaction
  • destinationTokenAddress (string): Contract address of the destination token
  • destinationToAddress (string): Recipient address on the destination chain

​
Optional Fields

  • tradeType (TradeType): Either EXACT_INPUT or EXACT_OUTPUT
  • destinationTokenAmount (bigint): Amount of destination tokens (only for EXACT_OUTPUT)
  • originTokenAmount (bigint): Amount of origin tokens (only for EXACT_INPUT)
  • destinationToAddress (string): Recipient address on the destination chain (defaults to ownerAddress)
  • destinationApproveAddress (string): Contract address to pre-approve on the destination chain before executing destinationCallData
  • destinationCallData (string): Custom calldata for contract interactions on destination chain
  • destinationCallValue (number): Value (in wei) to send with the destination call
  • fundMethod (FundMethod): Hint for the funding method — WALLET, DIRECT_TRANSFER, ONRAMP_MESH, or ONRAMP_MELD
  • onlyNativeGasFee (boolean): When true, restricts gas fee options to the origin chain’s native token only
  • options (QuoteIntentRequestOptions):
    • bridgeProvider (RouteProvider): Preferred bridge provider — AUTO (default), RELAY, CCTP, LZ_OFT, SUSHI, ZEROX, LIFI, WETH
    • bridgeProviderFallback (boolean): If true, fall back to another provider if the preferred bridge provider is unavailable
    • swapProvider (RouteProvider): Preferred same-chain swap provider — AUTO (default), RELAY, SUSHI, ZEROX
    • swapProviderFallback (boolean): If true, fall back to another provider if the preferred swap provider is unavailable
    • preference (RoutePreference): Route optimisation target — RECOMMENDED (default), FASTEST, CHEAPEST, TRUSTLESS
    • intentProtocol (IntentProtocolVersion): Force a specific intent protocol version — v1 or v1_5
    • slippageTolerance (number): Maximum acceptable slippage as a fraction of 1 (e.g. 0.005 for 0.5%)
    • trailsAddressOverrides (TrailsAddressOverrides): Custom Sequence wallet addresses for the intent

​
Response

The response includes:
  • intent (Intent): Complete intent object with transaction details
  • gasFeeOptions (GasFeeOptions): Available gas fee payment options

​
Intent Object Details

The intent object contains:
  • Unique intent ID
  • Transaction status
  • Deposit transaction details
  • Cross-chain calls to execute
  • Quote information (rates, slippage, price impact)
  • Fee breakdown (gas fees, provider fees)
  • Expiration timestamp

​
Example

const quoteRequest = {
  ownerAddress: "0x0709CF2d5D4f3D38f5948d697fE64d7FB3639Eb1",
  originChainId: 1, // Ethereum
  originTokenAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC
  originTokenAmount: 100000000, // 100 USDC (6 decimals)
  destinationChainId: 8453, // Base
  destinationTokenAddress: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", // USDC on Base
  destinationToAddress: "0x0709CF2d5D4f3D38f5948d697fE64d7FB3639Eb1",
  tradeType: "EXACT_INPUT",
  options: {
    slippageTolerance: 0.005, // 0.5%
    bridgeProvider: "RELAY"
  }
};

const response = await fetch('https://trails-api.sequence.app/rpc/Trails/QuoteIntent', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'X-Access-Key': 'YOUR_ACCESS_KEY'
  },
  body: JSON.stringify(quoteRequest)
});

const quote = await response.json();
console.log('Quote:', quote);

​
Quote Expiration

Quotes expire 5 minutes after being issued. You must commit the intent using CommitIntent before the quote expires, or you’ll need to request a new quote.

​
Next Steps

After receiving a quote:
  1. Review the quote details, fees, and estimated amounts
  2. Use CommitIntent to commit the intent before the quote expires (5-minute window)
