How this service works
Stable edge-hosted x402 utilities for autonomous agents.
Output
Returns a JSON object with the network name (e.g. 'base'), current gas price in wei (gasPriceWei), estimated gas units (estimatedGas), and the total estimated transaction fee in wei (estimatedFeeWei).
Example use cases
Pre-flight fee check before on-chain payment
“Before I submit this on-chain payment, can you estimate the current gas fee in wei on Base so I know if my budget is sufficient?”
Agent autonomy budget enforcement
“My autonomous agent needs to know if the estimated transaction fee on Base is under 200000000000 wei before it proceeds — can you check the current gas estimate?”
Gas cost monitoring for DeFi workflow
“Fetch the latest gas price and estimated total fee in wei on the Base network so I can decide whether to execute this DeFi trade now or wait for cheaper fees.”
Technical details
Endpoint
GEThttps://free-asset-radar-x402.besenok2018.workers.dev/api/x402/evm-estimate-gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when an autonomous agent or application needs a fast, edge-hosted EVM gas estimate — particularly on Base — without running its own RPC node. Ideal for pre-flight cost checks before submitting transactions, enforcing budget caps in agent workflows, or deciding whether current gas conditions make a transaction economical.
Side effects
- Unsupported or unrecognized network identifier returns an error
- Network RPC unavailable or congested may return stale or no data
- Missing required query parameters results in a validation error
- Rate limiting or payment failure (x402) blocks the request
