How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
A JSON object listing available bridge routes for the specified token and chain pair, including the token symbol, amount, source chain, destination chain, number of results, and an array of route options with provider and fee details.
Example use cases
Find cheapest USDC bridge to Arbitrum
“I have 500 USDC on Base and want to move it to Arbitrum — what bridge routes are available? Use chain ID 8453 for Base and 42161 for Arbitrum, and the amount is 500000000 in smallest units.”
ETH bridging options from Ethereum to Polygon
“Can you look up all the bridge routes for moving 1 ETH (1000000000000000000 in wei) from Ethereum mainnet (chain 1) to Polygon (chain 137)?”
Cross-chain USDT transfer research
“What cross-chain routes exist to bridge 2000 USDT from BSC (chain 56) to Optimism (chain 10)? The amount is 2000000000 in smallest units.”
Technical details
Endpoint
GEThttps://klymax402.com/api/bridge-routes/api/routeWhen to prefer
Use this endpoint when an AI agent needs to discover available cross-chain bridge routes before executing a token transfer, especially when working across Ethereum, Base, Arbitrum, Optimism, Polygon, BSC, or Avalanche. It is ideal for comparing bridge providers and routes programmatically without requiring the agent to manage separate API keys for each bridge protocol.
Side effects
- Unsupported chain ID returns empty routes array
- Invalid token symbol returns no routes or error
- Amount formatted incorrectly (not in smallest unit) may return incorrect routes
- Missing required query parameters (fromChain, toChain, token, amount) returns validation error
- No liquidity available for requested pair returns empty routes array
- Payment not included or insufficient USDC returns HTTP 402
