How this service works
Median fee rate forecast for a near-future block, committed as a Proof of Outcome claim.
Output
Returns a structured JSON object containing the product name, fee tier label, a forecast object with the median fee rate for the near-future block, a Proof of Outcome cryptographic commitment, the basis data underlying the forecast, and the source of the data. The Proof of Outcome allows downstream verification that the forecast was committed before block confirmation.

Choose this endpoint when you need a Bitcoin fee rate forecast that is not just a raw estimate but comes with a cryptographic Proof of Outcome commitment — making it auditable and verifiable after the fact. Ideal for automated payment pipelines, compliance-sensitive workflows, or any application where fee data integrity must be provable. Prefer this over generic mempool APIs when verifiable attestation of the forecast is a requirement.
