Agents can pay now. We built the rails.

The problem nobody talks about

The internet was never built for software to pay software.

Agents can call any API on the planet, but they hit a wall the moment money is involved. Card forms assume a human. API keys assume a signed contract and a monthly invoice. Subscriptions assume you can predict usage. None of that fits an agent that wants to spend a fraction of a cent on a single query, right now, with no paperwork.

So the most useful tools on the internet stay free — and unsustainable — because there has been no clean way to charge for a single call.

What Loomal actually is

Loomal is the payments layer for the agent internet. Wrap any HTTP handler or MCP tool with one line of middleware and it becomes a paid endpoint. People and AI agents pay per call in USDC. Every payment settles on Base in about two seconds and returns a cryptographically signed receipt.

Here is what that gives you:

• A paywall in a few lines — drop the middleware on any Express, Hono, FastAPI, or MCP handler. The first call returns a 402 payment requirement; the caller signs and retries; your handler runs.
• Per-call pricing in USDC — charge $0.01 on a fast query, $1 on a long job. Variable amount per call lets you pass through model costs plus margin.
• Settlement in seconds, no chargebacks — USDC settles on Base mainnet synchronously per call. Funds land in your project wallet immediately — never seven days, never a dispute window.
• Signed receipts and an audit timeline — every payment, refund, and cash-out is logged with an on-chain transaction link. Hand it to your accountant or a regulator. It holds up.
• Distribution via the Loomal Index — opt your paid endpoint into the index and buyer agents discover it, price-compare, and start paying — distribution included with the paywall.

Integration that meets you where you are

Loomal works on every framework that speaks HTTP, and ships a native MCP server. If you use Claude Desktop, Cursor, Claude Code, Windsurf, or any MCP-compatible client, monetising a tool is a configuration change — not a development project.

Prefer REST? The full API is clean, documented, and available for any stack or language. Getting paid should not be the hard part of shipping a tool.

See it for yourself

Open the console and create a project — you get a non-custodial smart wallet on Base and an API key. Wrap one route with the Loomal middleware, set a price, and deploy.

Then call your own endpoint without paying. Watch it return a 402 with the payment requirement, sign and retry, and settle in about two seconds — with a signed receipt and a chain link for every call.

Your first $100 of revenue is free. After that, Loomal takes 5% on settled payments — waived for now. No card, no monthly fee, no per-seat pricing.
