How this service works
Agent data gateway plus the live x402 market feed. Normalized, schema-stable JSON for crypto prices, DeFi TVL, on-chain DEX pools, gas, FX, US Treasury yields, US weather, WHOIS, DNS, email validation, web-page extraction, tech news, Wikipedia, npm/PyPI package health, ERC-20 token-risk scoring, and composed domain dossiers, plus x402 ecosystem analytics and metered LLM inference. Pay per call with USDC via the x402 protocol; no accounts, no API keys.
Output
Returns a JSON object with ok:true and a data block containing: chain name, gas price in Wei and Gwei, number of blocks sampled, estimated next base fee in Gwei, and priority fee percentiles (p25, p50, p75) in Gwei. Also includes meta fields: whether the result was cached, the data source (on-chain via PublicNode/dRPC), and the fetch timestamp.
Example use cases
Pre-transaction gas check for DeFi bot
“Before I submit this swap on Base, what's the current gas price in Gwei and what priority fee should I use to get included in the next block without overpaying?”
Gas cost monitoring for Ethereum bridge
“Check the current gas price on Ethereum and tell me the next base fee estimate — I want to know if it's worth bridging assets right now or if I should wait for fees to drop.”
Cross-chain gas comparison for L2 selection
“Pull the live gas prices for Base and Polygon so I can compare which network is cheaper to deploy my contract on today.”
Technical details
Endpoint
GEThttps://gateway.stride20k.com/crypto/gas/%7Bchain%7DWhen to prefer
Choose this endpoint when you need real-time, EIP-1559-aware gas fee data for Ethereum, Base, or Polygon without setting up your own RPC node or API key. It is ideal for pre-transaction gas checks, cost estimation, and fee optimization in agent workflows. Prefer this over raw RPC calls when you want normalized Gwei output and priority fee percentiles in a consistent schema. Pay-per-call with USDC via x402 makes it suitable for low-frequency or sporadic usage without subscription overhead.
Side effects
- Unsupported chain slug returns an error or empty response
- Node RPC timeout causing delayed or failed response
- Stale cached data if cache TTL is not fresh
- Invalid chain path parameter format causes routing failure
- Network congestion on the queried chain may cause RPC latency
