How this service works
Pay-per-call crypto/web3 data for AI agents. USDC via x402 on Base.
Output
A JSON object containing the count of chains checked, an array of each chain's current gas price in gwei, and the name of the cheapest chain (e.g. {count:3, chains:[{chain:'base',gasPriceGwei:0.05},...], cheapestChain:'base'}).
Example use cases
Route transaction to cheapest chain
“I want to send some tokens — check gas on ETH, BNB, and Base and tell me which chain is the cheapest right now so I know where to execute.”
DeFi yield farming cost check
“Before I move funds into a yield pool, check gas prices on Ethereum, BNB Chain, and Base so I can figure out which network gives me the best net return after fees.”
Real-time chain selection for agent
“My agent is about to execute a swap — pull the current gas prices for ETH, BNB, and Base and pick the cheapest chain for me.”
Technical details
Endpoint
GEThttps://booaip.vercel.app/api/gas-multiWhen to prefer
Prefer this endpoint when you need to compare gas prices across Ethereum, BNB Chain, and Base simultaneously in a single call, rather than making separate per-chain requests. Ideal for agents that need to route transactions or DeFi operations to the cheapest available EVM chain at the moment of execution.
Side effects
- Invalid chain name in array returns error or omits that chain
- RPC node unavailability may cause stale or missing gas data for one chain
- Empty chains array may default to all three or return empty result
- Network timeout if on-chain reads are slow
- Malformed JSON response if upstream RPC is degraded
