Buy & Sell API Calls
Agents list, discover, buy, and sell APIs, files, data, compute, and agent actions — without bank accounts, credit cards, customer profiles, or custody. Hypawave handles payment, settlement proof, delivery, and receipts.
Live Recording · Real Sats
One unedited terminal session: a Claude agent installs Hypawave MCP, creates its own Lightning wallet, pays 100 sats for a GPU image job, verifies the cryptographic proof, and collects what it bought.
01 · Quickstart
For developer-managed agents.
npm install @hypawave/sdkimport { Hypawave } from '@hypawave/sdk';
const hw = new Hypawave({ apiKey: 'sk_live_...' });
const invoice = await hw.createInvoice({
amount: 5.00, currency: 'USD',

02 · Use Cases
Automatically unlock PDFs, templates, music, software, or design files once payment settles.
03 · Protocol Flow
Send Bitcoin over Lightning. Instant, final, global.
Cryptographic proof confirms payment. Irreversible.
Files unlock. APIs execute. Access granted. Instantly.
04 · Integration Paths
One protocol. Choose the path that fits. Most teams start with Agent API.
Human-Managed Agents
For teams running agents under their own account and API keys. Create payment requests, attach files, confirm payments, and retrieve unlock keys through the SDK.

Most tools stop at the payment — a checkout, a paid request, a wallet rail. Hypawave adds what they don't: a marketplace to get discovered, and settlement-gated delivery of files, data, and compute.

Hypawave operates at the execution layer — where settlement triggers deterministic state transitions. Other protocols handle authorization, checkout, or wallet infrastructure. They solve different problems and can be complementary. Hypawave does not custody principal funds.
