Example use cases
Example prompt

Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/kaspa-derivatives/fee-estimateWhen to prefer
Use this endpoint when you need live, node-native Kaspa fee estimates across three priority tiers directly from the Toccata RPC estimator, rather than deriving fees from third-party APIs or block explorers. Ideal for wallets, transaction builders, or monitoring tools that need real-time Kaspa fee market data.
Side effects
- Node RPC unavailable — upstream Kaspa node connectivity issue
- Stale or cached data if node is behind the chain tip
- HTTP 402 if payment not included or insufficient
- Network timeout if node is under heavy load
- Empty or null bucket values if mempool is nearly empty
