gas history data for AI agents.
Output
A JSON object containing a time series of historical gas prices (in gwei or equivalent units), including timestamps and fee levels across the requested period for the specified blockchain network
Example use cases
DeFi transaction cost optimization
“Show me the gas fee history for Ethereum over the last 24 hours — I want to know when prices dipped lowest so I can schedule my next DeFi trade at the cheapest time.”
Smart contract deployment cost analysis
“Pull historical gas prices for Ethereum for the past 30 days — I'm trying to figure out the average cost to deploy a smart contract and whether fees have been going up or down.”
On-chain analytics dashboard
“I need a week's worth of gas price data for my blockchain analytics dashboard — can you fetch the historical gwei values with timestamps so I can plot the trend?”
Technical details
Endpoint
POSThttps://eltociear-tokenguard.hf.space/gas_historyWhen to prefer
Choose this endpoint when you need historical gas price data for on-chain cost analysis, DeFi strategy optimization, or transaction timing decisions. It is part of the broader TokenGuard crypto/DeFi data suite, making it ideal when you are already using other TokenGuard endpoints for ERC-20 safety or market data and want consistent data provenance.
Side effects
- Invalid or unsupported network identifier returns an error
- Date/block range too large may result in timeout or truncated data
- Missing required parameters (network, time range) returns 400-level error
- Payment failure via x402 micropayment blocks request
- Hugging Face Space may be cold-started, causing initial latency spike
