How this service works
Blockchain data APIs with x402 payments on Solana + Base via PayAI facilitator. 7 endpoints covering bridge routing, whale alerts, DeFi yields, RPC, NFT, token, and transaction history.
Output
Returns a recommended bridge route including the optimal bridging protocol, estimated output amount after fees, estimated transfer time, and step-by-step routing path for the specified token transfer between source and destination chains.
Example use cases
Cheapest cross-chain USDC transfer
“I need to move 1000 USDC from Base to Solana — find me the best bridge route with the lowest fees.”
DeFi portfolio rebalancing across chains
“I want to shift 2 ETH from Ethereum mainnet to Arbitrum — what's the optimal bridge route for that?”
NFT mint funding across chains
“I have funds on Polygon but need USDC on Solana — find the best bridge route to move 250 USDC from Polygon to Solana.”

Endpoint
POSThttps://solana-x402-xi.vercel.app/api/v1/bridge-routeWhen to prefer
Choose this endpoint when you need real-time cross-chain bridge routing recommendations specifically involving Solana or Base as source/destination chains; it supports x402 micropayments natively making it suitable for AI agents with crypto wallets, and covers chains like Ethereum, Base, Polygon, Arbitrum, and Solana in a single call.
Side effects
- Unsupported chain pair returns an error or empty route
- Invalid token symbol or address returns a validation error
- x402 payment of $0.005 USDC fails if wallet is underfunded
- Amount too small or too large for available bridge liquidity
- Network congestion may cause stale or suboptimal route data
