How this service works
Base fee now and next block, 24h band, utilisation trend, cost per operation type
Output
Returns a JSON object containing: current base fee (in gwei or USDC), next block base fee estimate, 24-hour fee band (min/max), network utilisation trend, and cost per operation type (e.g. ETH transfer, ERC-20 transfer, contract interaction).
Example use cases
Pre-transaction gas cost check
“Before I submit this Ethereum transaction, what's the current base fee and what's it expected to be next block? I want to know if I should wait or submit now.”
DeFi bot fee optimisation
“What's the 24-hour gas fee band and current network utilisation trend on Ethereum? I need to decide the best time window to run my arbitrage transactions today.”
Gas cost breakdown by operation
“Show me the current gas fee forecast including cost per operation type — I want to know exactly how much an ETH transfer, a token swap, and a contract interaction would cost me right now.”
Technical details
Endpoint
GEThttps://api.cra-agent.tech/v1/paid/fees/forecastWhen to prefer
Choose this endpoint when you need a comprehensive gas fee forecast in a single call — combining current base fee, next-block prediction, 24-hour band context, utilisation trend, and per-operation cost breakdowns. Prefer over simple gas price APIs when you need historical context (24h band) alongside real-time data, or when you need cost estimates broken down by transaction type rather than a single gas price figure.
