How this service works
Live Ethereum mainnet gas pricing from PublicNode RPC: next-block base fee, 25/50/75th-percentile priority tips over the last 5 blocks (slow/std/fast), and a ready-to-sign recommendation (max_fee = 2*base + tip). Query: ?speed=slow|std|fast (default std). All values are decimal gwei, no hex parsing needed. 30s cache.
Output
Returns decimal gwei values for: the next-block base fee, the 25/50/75th-percentile priority tips (labeled slow/std/fast), and a ready-to-sign max_fee recommendation (calculated as 2*base_fee + tip). Values are cached for 30 seconds. No hex parsing needed.
Example use cases
Example prompt
“What's the current Ethereum gas price for a standard-speed transaction — give me the base fee, priority tip, and the max fee I should set when signing?”
Technical details
Endpoint
GEThttps://x402-datashop-production.up.railway.app/v1/eth/gasWhen to prefer
Use this endpoint when you need real-time EIP-1559-compatible Ethereum gas parameters in decimal gwei without doing any hex decoding, especially when you need a ready-to-sign max_fee recommendation. Prefer this over raw RPC calls when simplicity and a cached, pre-computed recommendation are more important than absolute freshness.
Side effects
- PublicNode RPC is unreachable — upstream 502 or timeout
- Invalid speed parameter value returns 400 or defaults to std
- Cache stale if Ethereum network conditions change rapidly within 30s window
- No historical data available — only latest block window (last 5 blocks)
