How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
Returns a JSON object with the network name, current gas price in Gwei, ETH price in USD, and an estimated_cost breakdown for an ERC-20 transfer showing the cost in both ETH and USD. Example: {network: 'base', gas_price_gwei: 0.006, eth_price_usd: 2691.22, estimated_cost: {transfer_erc20: {eth: 4.3e-7, usd: 0.0012}}}
Example use cases
Pre-trade gas cost check
“Before I send those USDC tokens on Ethereum, can you check what the current gas price is and how much the transfer will cost me in USD?”
Base network fee monitor
“What are the current gas fees on Base network, and what's the estimated cost of an ERC-20 transfer right now in both ETH and USD?”
Cheapest network routing decision
“I need to do an ERC-20 transfer — can you check the gas prices on both Ethereum and Base so I can figure out which one is cheaper right now?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/gas-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time EVM gas price data for Base or Ethereum networks, especially when you need both the raw Gwei price and a pre-calculated USD cost estimate for ERC-20 transfers. It is ideal for agents that need to make cost-benefit decisions before submitting on-chain transactions or routing between networks. Prefer this over on-chain RPC calls when you want a simple pay-per-call REST API without managing your own node connections.
Side effects
- Invalid network value (not 'base' or 'ethereum') returns an error
- RPC node unavailability may cause timeout or null values
- Missing required 'network' field in body returns validation error
- Network congestion may cause stale or delayed gas data
