How this service works
chainquery Bitcoin RPC: pay-per-call Bitcoin Core over x402, no API key. Raw fee-estimate data from the node's fee estimator for a confirmation target. Bitcoin Core estimaterawfee.
Output
A JSON object containing the raw output of Bitcoin Core's estimaterawfee RPC call: per-confirmation-target fee rate data including short, medium, and long horizon buckets, each with pass/fail statistics, fee rates, start/end ranges, and the number of transactions in each bucket.
Example use cases
Example prompt
“What does Bitcoin Core's raw fee estimator return for a confirmation target of 6 blocks — give me the full bucket breakdown including pass and fail stats?”
Technical details
Endpoint
GEThttps://x402.chainquery.com/v1/rpc/estimaterawfeeWhen to prefer
Use this endpoint when you need granular, raw fee estimation data from a real Bitcoin Core node without provisioning your own infrastructure or API key — especially useful for fee analysis, building custom fee selection logic, or debugging fee estimator behavior. Prefer over estimatesmartfee when you need the full histogram/bucket data rather than a single recommended fee rate.
Side effects
- Invalid or missing confirmation target param returns RPC error
- Malformed JSON in params query string returns parse error
- Payment not processed or x402 payment header missing/invalid returns 402
- Node temporarily unavailable returns 5xx
- Confirmation target out of supported range (1-1008) returns RPC error
