​
Overview

Route V2 endpoint provides the same routing functionality as V1, with additional features including integrator support, enhanced metadata, and improved response structure. Currently available on EVM networks.
V2 API is currently available on Evm networks. V1 endpoints remain available for backward compatibility.

​
Endpoint

https://api.fibrous.finance/{network}/v2/route
Find the optimal trading route through Fibrous’ integrated liquidity sources to maximize output and minimize slippage. This endpoint analyzes multiple protocols, pool depths, and potential paths to deliver the most efficient swap execution for your tokens.

​
What’s New in V2

Integrator Support

Monetize your integration with fees or surplus sharing

Enhanced Metadata

All responses include API version and timestamp

Better Tracking

Track output amounts before and after fees

API Key Support

Use API keys for higher rate limits and integrator features

​
Query Parameters

​
amount
string
required
The amount of input tokens in wei format. For tokens with 18 decimals, multiply the amount by 10^18.Example: "1000000000000000000" for 1 token
​
tokenInAddress
string
required
The address of the input token.Example: "0x0000000000000000000000000000000000000000" for native token
​
tokenOutAddress
string
required
The address of the output token.Example: "0x3bd359c1119da7da1d913d1c4d2b7c461115433a" for wrapped token
​
reverse
boolean
Not supported yet - reserved for future use. Default: false
​
direct
boolean
If true, only direct swaps between the input and output tokens will be considered. Default: false
​
excludeProtocols
string
Comma-separated list of protocol IDs to exclude from routing (e.g., “1,2,3”). Default: ""
​
integratorAddress
string
Integrator wallet address to receive fees or surplus. Requires API key authentication.
​
integratorFeePercentageBps
number
Integrator fee percentage in basis points (0-500, maximum 5%). Cannot be used together with integratorSurplusPercentageBps.
​
integratorSurplusPercentageBps
number
Integrator surplus percentage in basis points (0-5000, maximum 50%). Cannot be used together with integratorFeePercentageBps.
API Key Required: Integrator features (integratorAddress, integratorFeePercentageBps, integratorSurplusPercentageBps) require an API key. Partners must obtain an API key from Fibrous to use these monetization features. Include the API key in the request headers as X-API-Key.

​
Response

​
success

Integrator Features

API Key Required: To use integrator features, partners must obtain an API key from Fibrous. Contact us at [email protected] or join our Discord to request an API key.
To use integrator features, include your API key in the request headers: 
const headers = {
  'X-API-Key': 'your-api-key-here'
};

const params = {
  amount: '1000000000000000000',
  tokenInAddress: '0x0000000000000000000000000000000000000000',
  tokenOutAddress: '0x3bd359c1119da7da1d913d1c4d2b7c461115433a',
  integratorAddress: '0xYourWalletAddress',
  integratorFeePercentageBps: 100 // 1% fee
};

const response = await fetch('https://api.fibrous.finance/{network}/v2/route?' + new URLSearchParams(params), {

});
You cannot use both integratorFeePercentageBps and integratorSurplusPercentageBps in the same request. Choose one monetization method.

Best Practices

  1. Always check meta.apiVersion to ensure you’re using the expected API version
  2. Use API keys for production integrations to access integrator features
  3. Monitor meta.timestamp for debugging and tracking response times
  4. Handle outputAmountAfterFee when using integrator fees to show accurate amounts to users
