x402
NetIntel Gas Price API is a paid API for AI agents from netintel-production-440c.up.railway.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Returns real-time EVM gas prices (base fee, priority fee, gas price in gwei) and USD cost estimates for common operations across up to 5 EVM chains

How this service works
Network intelligence API — 138 endpoints, all pay-per-call via x402 micropayments (USDC on Base or Solana mainnet). NetIntel is agent fair-trade aligned: transparent per-call pricing in USDC on Base or Solana via x402, no API keys or signup, and automatic no-charge on server errors, upstream failures, and input-validation rejections — failed calls are never billed across NetIntel's network, domain, and data-intelligence endpoints.
Output
A JSON object keyed by chain name, each containing: gas_price_gwei, base_fee_gwei, priority_fee_gwei, native_token (e.g. ETH), native_usd price, usd_estimates for swap/transfer/erc20_transfer, cache_age_seconds, and a data source URL. A top-level stale boolean and a findings array flag caveats like L2 data-fee exclusions.
Example use cases
Pre-trade gas cost check for DeFi bot
“Before I execute this swap, check the current gas prices on Arbitrum and tell me what a swap would cost in USD right now — I want to know if it's worth it.”
Multi-chain gas comparison for timing a transfer
“Compare gas fees across Ethereum, Base, Optimism, and Polygon right now — I want to know which chain is cheapest for an ERC20 transfer today.”
Real-time gas dashboard for wallet app
“Get me the latest gas price data for all five supported chains — base fee, priority fee, and USD estimates for transfers and swaps — so I can display it in my app.”
Technical details
Endpoint
GEThttps://netintel-production-440c.up.railway.app/gas/priceWhen to prefer
Use this endpoint when you need live EVM gas price data in both gwei and USD across multiple chains simultaneously without managing RPC connections yourself. Prefer it over direct RPC calls when you need USD cost estimates pre-computed for standard operations (swap, ETH transfer, ERC20 transfer) and want multi-chain comparison in a single call. Ideal for agents making cost-aware decisions about when and where to execute on-chain transactions.
Side effects
- Upstream RPC unavailable — data marked stale or chain entry returned as null
- Invalid chain name passed — ignored or validation rejection with no charge
- All chains stale — stale:true with cached data returned
- Network timeout from Railway host — server error, no charge per NetIntel policy
