Free to start.
We're never in the funds path.

The software is free: the bolthub Pay SDK is open source (MIT), self-hosts with no account, and you keep 100% of what you charge. Want us to run it? The hosted platform is one subscription with one meter, covering the no-code gateway and the hosted facilitator behind your SDK integration. Your customers' per-call payments still settle straight to your wallet.

The numbers below are the hosted platform's bill. Consuming tools instead? Each provider sets its own per-call price — see paying for tools.

Everything else is free. Not freemium, free.

One subscription covers all hosted infrastructure. Every other product has no bolthub price tag at all.

bolthub Pay SDK + ToolClient

Sell tools and buy tools in code. Open source (MIT), zero runtime dependencies, no account. Self-host and keep 100% of what you charge.

Free

API Hub

Browsing, searching, and calling listed tools is free for everyone. Listing your own tools is included in the hosted platform.

Free

Node Launcher

bolthub adds no fee. You pay your VPS provider directly, from ~$3.50/month, and you hold the keys.

Free

Self-hosting, forever

The whole payment layer runs without bolthub. The subscription buys managed infrastructure, not permission.

Your prices are a different table. Yours.

What you charge your buyers is set by you, per endpoint or per tool, and none of it goes to bolthub. On the hosted gateway you can choose from five pricing models (per request, per KB, token bucket, time pass, metered); with the Pay SDK you set a per-call price in code.

How billing works

Two independent flows. Your customers pay you per call, directly to your Lightning wallet. Those sats never touch bolthub. Separately, bolthub bills you a monthly fee for running the hosted infrastructure (gateway or facilitator), hub listing, and analytics. That's the only money bolthub ever sees from you.
