How this service works
Security intelligence layer for autonomous agents. On-chain security, token risk analysis, wallet forensics, and transaction simulation. Pay-per-call via x402 on Base.
Output
Returns the current gas prices across Base, Ethereum, Arbitrum, and Optimism networks, identifying the cheapest chain for sending a transaction at the time of the request. Likely includes fee estimates (e.g. fast, standard, slow in gwei) per chain and a recommendation for the lowest-cost option.
Example use cases
Cheapest chain for token transfer
“I need to send some tokens to a friend — which of Base, Ethereum, Arbitrum, or Optimism has the lowest gas fees right now so I'm not overpaying?”
DeFi swap cost optimization
“I'm about to do a DeFi swap and want to minimize fees — can you check live gas prices across Base, Arbitrum, Ethereum, and Optimism and tell me which chain I should use?”
Automated transaction routing
“Before I submit this transaction, check which EVM chain currently has the cheapest gas so my agent can route it to the right network automatically.”
Technical details
Endpoint
GEThttps://economic-agent-369.freysa.dev/api/gas-routerWhen to prefer
Use this endpoint when you need a real-time cross-chain gas comparison specifically across Base, Ethereum, Arbitrum, and Optimism. Prefer it over single-chain gas endpoints when your goal is to route a transaction to the cheapest available EVM network rather than just monitor a specific chain. Ideal for cost-optimization workflows, DeFi bots, and agent-driven transaction routing.
Side effects
- Upstream gas oracle unavailability causing stale or missing price data
- Network timeout when fetching live prices from one or more chains
- Payment failure (x402) if USDC balance is insufficient for the $1 call fee
- Transient price spikes may cause the recommended chain to change within seconds of the response
