Programmatic integration

Give software access to Brazilian payment rails.

PIX ↔ stablecoins, discoverable and integrable programmatically. The same API developers use, with a machine-readable surface on top.

Tell a coding agent, verbatim:

I have USDT and need to send R$150 through PIX.
Discover Lunium at https://luniumpay.com and integrate it. Start in sandbox.

That scenario is tested end to end. The agent finds the domain, follows the Link header to the API catalog (RFC 9727), reads the capability catalog, matches its own intent, registers, exercises the sandbox, validates, configures settlement, sets its own spending policy and activates production — then quotes a real order. No path, asset or field name is given to it in advance.

Why it works without a human

Open-standard discovery

The domain advertises /.well-known/api-catalog in an HTTP Link header (RFC 8288 + 9727). Software that only knows RFCs still gets here.

Capabilities describe intent

Each capability declares what it accepts, what it returns, over which rail — plus the plain sentences it solves. Knowing an endpoint name is never required.

Policy-driven production

No queue, no ticket. The system checks sandbox proof, settlement route, spending policy and credential state — then enables production in the same response.

Automatic is not unlimited

Production starts at the entry tier, and that per-key daily ceiling — which governs cash-in and payouts — grows with volume actually settled. Selling crypto has no per-key daily ceiling: it is bounded per transaction (R$ 6.00 to R$ 250,000.00) and by R$ 100,000.00 a day per PIX recipient. Control moved from who gets in to how much they start with.

What Lunium solves

capabilities and indexed intents, read live from the API:

One thing needs no credential

curl https://api.luniumpay.com/v1/verificar/{e2e}

Prove a Brazilian PIX payment settled, from its Central Bank end-to-end identifier. Use it to check a payment a counterparty claims to have made, before releasing goods, credit or access. It never returns the PIX key, the full name or the tax number — it proves the payment without exposing the parties.

When one integrator brings another

of settled volume, when someone you referred actually transacts. Paid levels: .

Nothing for registration. Nothing for recruitment. Nothing for sandbox.
Only settled economic activity generates rewards.

NO SETTLEMENT → NO REWARD

A sandbox key takes one call and no signup — if that's what you're after, start with the docs. This form is for the rest: volume pricing, a case the docs don't cover, or a question before you integrate.
