Payments infrastructure for AI agents

Tael lets any API, model, or service charge autonomous agents per call, in USDC, settled on Stellar. No billing system to build. No accounts to manage. No integration beyond a single line of code. You bring your endpoint; Tael becomes the revenue layer in front of it.

You built something worth paying for. An API, a model, a data feed, an agent. The product was never the hard part. Everything around getting paid for it was: the billing system, the customer accounts, the API keys, the rate limits, the invoices, the sales calls, the integrations. Months of work that has nothing to do with what you actually made.

What Tael runs for you

• Billing. We handle it. No Stripe, no invoices, no subscriptions, no metering, no chasing payments. Every call settles in USDC on Stellar, automatically and non-custodially, straight to your wallet in the same transaction.
• Accounts and auth. We handle it. You never issue an API key, set a rate limit, or manage a customer. Tael's gateway is the front door for every buyer. You get called, you get paid.
• Distribution. It happens here. Your service lives in a marketplace that agents search, discover, and call on their own. No demos, no onboarding, no selling one customer at a time.
• Integration, on their side. You publish once. After that, anyone can wire your product into theirs in a few lines: they point the Tael SDK at your capability, and their agent pays for it and calls it. Every integration is theirs to write, not yours.
• Migration. None. Your endpoint stays exactly where it is. Tael sits in front of it as a metered gateway. There is nothing to rebuild.

The part that changes everything

Once your service is on Tael, any autonomous AI agent can pay for it and use it, per call, with a single key, no human in the loop. You are no longer selling to people who evaluate, negotiate, and expense. You are selling to software that finds a capability, pays for it, and keeps working.

What it costs you to join

One line.

import { Tael } from "@tael/sdk";
const tael = new Tael({ apiKey: process.env.TAEL_KEY });

await tael.publish({
  name: "My API",
  kind: "api",
  endpoint: "https://api.example.com/v1",
  payTo: "G...",
  operations: [{ name: "Predict", path: "/predict", price: "0.01" }],
});

That is the whole integration. Your capability goes live, agents can call it, and USDC lands in your wallet on every request. Install it with pnpm add @tael/sdk.
