Bitcoin fee recommender.

Current sat/vByte rates for fast / standard / economy confirmation on the chainkit SDK. Sourced from real provider RPC — the same routing logic that runs in production for our customers.

how this works

Same SDK we ship to customers.

This page calls /v1/public/btc/fees, which asks the chainkit SDK to recommend fee tiers across whatever providers are in rotation. The SDK picks the healthiest one, retries on failure, scores them down on slow responses — exactly the behaviour you get when you build your own app with chainkit.

API · same call, in code

Use this in your code.

The lookup above is a real call to chainkit's public API. Here's the same request as curl, in Go via the SDK, and the raw JSON response — everything you need to wire it into your own app.

$ curl

curl -sS '/v1/public/btc/fees'

client.go

tiers, err := provider.GetTxFees(ctx)
if err != nil {
    log.Fatal(err)
}
for _, t := range tiers {
    fmt.Printf("%d sat/vB · ~%d blocks\n", t.FeeRate, t.TargetBlock)
}
