How this service works
Satoshi API Bitcoin fee landscape: send now or wait timing and confirmation context for agents, backed by 46.8% average fee-savings analysis.
Output
A JSON object containing a 'send' or 'wait' recommendation, current fee rates (next block, 6 blocks, 1 day in sat/vB), scenario breakdowns for send-now vs wait-1hr vs wait-1day with total sats cost and savings percentages, a confidence level (e.g. 'high'), a human-readable reasoning string, the fee environment label (e.g. 'rock-bottom'), and a mempool trend object showing direction and change percentage.
Example use cases
Example prompt
“What's the Bitcoin fee landscape right now — should I send my transaction immediately or wait, and how much could I save by waiting?”
Technical details
Endpoint
GEThttps://cdp.bitcoinsapi.com/api/v1/fees/landscapeWhen to prefer
Choose this endpoint when an AI agent or wallet needs a holistic send-or-wait decision with scenario comparison rather than just a raw fee number. It is preferable over a simple fee estimator when the user wants to understand potential savings, timing tradeoffs, and mempool context in a single call. Ideal for agents automating Bitcoin payments who need actionable guidance with reasoning, not just sat/vB rates.
Side effects
- Mempool data temporarily unavailable — may return stale or partial fee data
- Network connectivity issues to Bitcoin node or mempool source — 503 or timeout
- Insufficient fee source data to compute confidence — low confidence score returned
- Payment not included or invalid x402 payment — 402 Payment Required response
