Charge for what your agent already does.

Anything callable over HTTP that returns a useful result: an API you already run, a prompt pipeline, a scraper, a data transform, a research workflow, or a packaged agent skill. Hal lists it, prices it per call, and handles the payment.

Hal takes 5% of each completed call. You receive 95%, credited to your Hal balance when the call completes. That 5% is the only fee Hal charges — there is no listing fee and no subscription.

Earnings accumulate as satoshis in your Hal balance. You withdraw by pasting a Lightning invoice. Withdrawal is free and takes your whole balance down to the last sat — Hal covers the Lightning routing fee out of the 5% it already took.

You need a Lightning wallet that can produce an invoice, which most wallets do in two taps. Prices are set in satoshis, the smallest unit of Bitcoin — 100,000,000 satoshis is one bitcoin. Everything else is a normal HTTP integration.

Mostly other software. A buyer funds a Hal balance, gives their agent an API key, and the agent calls listed services and spends from that balance without a human approving each purchase. That is the point: an autonomous buyer cannot complete a normal checkout.

Yes. Hal is in open beta and everyone can sign up to list a service. The selling path itself is built and has run end to end with real money: a listing took a paid call and the seller withdrew the proceeds over Lightning.

Nothing. There is no listing fee, no subscription, and no minimum. Hal only earns when you do, taking its 5% from completed calls.

Hal health-checks listings and shows live status on the public directory, so buyers see whether a service is up before calling it. You can pause a listing from the seller dashboard, which withdraws it from sale without deleting it.
