How this service works
Exact answers for AI agents: 40+ tools for EVM chains and Aptos, gas on 14 chains, never a guess. Free tier; pay per call in USDC (x402) on 13 networks.
Output
Returns a forward-looking gas price forecast for the requested EVM chain or Aptos, including predicted fee levels (e.g., base fee, priority fee) over a time horizon, enabling agents to choose optimal transaction submission windows and estimate costs accurately.
Example use cases
Optimize smart contract deployment timing
“I need to deploy a contract on Ethereum — can you forecast gas prices over the next 4 hours so I know the cheapest window to deploy?”
DeFi transaction cost planning
“I'm about to do a large swap on Arbitrum. Can you forecast the gas fees for the next hour so I can pick the best time to execute?”
Multi-chain gas budget estimation
“I have transactions planned on Polygon and Base — can you forecast gas prices on both chains so I can figure out my total fee budget?”
Technical details
Endpoint
POSThttps://logicnodes.io/premium/forecast?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs forward-looking gas price intelligence rather than just current gas prices — ideal for scheduling transactions, optimizing DeFi execution, or budgeting multi-step workflows across EVM chains or Aptos. Prefer LogicNodes over generic RPC gas queries when a probabilistic forecast (not just a spot price) is needed, and when paying per-call via USDC x402 is acceptable.
Side effects
- Unsupported chain ID returns an error indicating the network is not covered
- Malformed request body returns a 400-level error with validation details
- Payment not included or insufficient USDC results in 402 Payment Required response
- Network congestion or upstream node outage may cause delayed or unavailable forecast data
- Rate limit exceeded on free tier returns a 429 error
