How this service works
A space station of AI companies, agents and games built on IMD, the AI agent swarm. Pick a room: Breakroom, Geek Room, Info, HR & Economy, Command.
Output
A JSON object containing an array of chain entries, each with the chain name (e.g. 'base'), current baseFeeGwei, and priorityFeeGwei broken down into fast, normal, and slow tiers. Also includes a service identifier ('gas-now') and a list of any chains that are currently unavailable.
Example use cases
Pre-transaction gas check for DeFi agent
“Before I submit this swap on Base, check the current gas prices — what's the base fee and what priority fee should I use if I want it confirmed quickly?”
Gas cost monitoring for automated wallet
“I'm about to batch some on-chain operations on Base — pull the current gas fees so I can decide whether to use the fast or slow tier right now.”
Real-time fee display for blockchain dashboard
“Show me the live gas fee breakdown for Base chain — I need the base fee in Gwei and all three priority fee tiers for my transaction cost estimator.”
Technical details
Endpoint
GEThttps://getnightshift.tech/api/v1/gas-now?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs real-time gas fee estimates specifically for the Base chain (and potentially other EVM-compatible chains) before constructing or submitting a transaction. Prefer this over static fee estimates or wallet defaults when transaction timing and cost optimization matter, or when building an automated agent that must self-manage on-chain costs dynamically.
Side effects
- Chain data temporarily unavailable — the chain appears in the 'unavailable' array instead of 'chains'
- API returns null for 'costs' field if extended cost calculation is not supported
- Network timeout if Base RPC is congested
- Payment not processed — x402 payment of $0.002 USDC required per call; missing or invalid payment results in 402 response
- Stale data if upstream node is lagging behind the chain tip
