A single subscription covers everything — the non-custodial Bitcoin payment processor and the RPC telemetry that ships with it. You're billed on what you actually settle (a monthly minimum plus a fee that falls as you grow), never per event, never two separate bills.
Same platform at every tier — the more you settle, the lower your fee, and the more telemetry, retention, and projects you get.
One. A single subscription covers the non-custodial Bitcoin payment processor and the RPC telemetry that ships with it — ingest, retention, projects, alerting. There's no separate "RPC" plan to buy and no second invoice; your tier sets both your payments fee and your telemetry allowance.
On what you settle. Each month you pay the greater of your plan's monthly minimum or your settled volume × the plan fee — never both stacked, never per event. The fee falls as you move up a tier, so scaling up lowers your rate rather than surprising you. Plans are billed in EUR; your customers can pay their Bitcoin invoices priced in any supported fiat currency.
