Output
A JSON object containing the chain ID (8453 for Base), the current base fee in gwei, three priority fee suggestions (low, medium, high) in gwei, and USD cost estimates for a standard 21,000-gas ETH transfer and a 65,000-gas ERC-20 transfer.
Example use cases
Pre-flight gas check before sending USDC
“Before I send this USDC payment on Base, check the current gas fees and tell me how much the transfer will cost in USD so I know if now is a good time.”
Auto-select priority fee for DeFi bot
“My trading bot needs to submit a transaction on Base — pull the current base fee and low/medium/high priority fee suggestions so it can pick the right fee tier.”
Gas cost dashboard for Base activity
“Show me the current Base network gas stats: base fee in gwei, the three priority fee tiers, and the dollar cost for both a plain ETH transfer and an ERC-20 transfer.”
Technical details
Endpoint
POSThttps://xhagents.xyz/api/gas-tracker?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time Base network gas pricing with USD cost context — especially useful for agents that need to decide whether to submit a transaction, select a priority fee tier, or display human-readable cost estimates. Prefer over raw RPC calls when you want pre-computed USD estimates alongside gwei values without managing your own ETH price feed.
Side effects
- Invalid or unsupported chain_id returns an error or empty result
- Network connectivity issues to Base RPC may cause stale or missing fee data
- Fee data may lag slightly behind the latest block if the underlying RPC is slow
