How this service works
x402 pay-per-call onchain API (Base + Arc).
Output
Returns a JSON object containing the queried chain name, current gas price in Gwei, and fee estimates for a standard ERC-20 transfer at 65k gas expressed in USDC, along with the fee unit label.
Example use cases
Pre-transaction fee check on Base
“Before I send this USDC transfer, can you check what the current gas fees look like on Base so I know what to expect?”
Comparing fees across chains
“Can you pull the current network status and fee estimates for both Base and Arc so I can decide which chain is cheaper to transact on right now?”
Monitoring gas spikes on Arc
“What's the current gas price on Arc in Gwei, and how much would a standard ERC-20 transfer cost in USDC at this moment?”
Technical details
Endpoint
GEThttps://northline-chainkit.northline-c86.workers.dev/v1/network/status?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time gas price data and ERC-20 transfer fee estimates specifically for Base or Arc EVM-compatible chains, and you are operating in an x402 pay-per-call agent environment. Prefer this over general gas trackers when you need fee estimates denominated directly in USDC for programmatic decision-making.
Side effects
- Invalid chain parameter (not 'base' or 'arc') returns a validation error
- Network unavailability on the queried chain may return stale or error response
- Payment failure via x402 (insufficient USDC balance) blocks the call
- Worker timeout if the underlying RPC node is unresponsive
