Lirium API Documentation
The Crypto Infrastructure API for Latin America and Europe
Lirium lets you embed crypto trading, custody, and fiat on/off-ramps directly into your product — without building the exchange, custody, or banking connections yourself.
Who is it for? Fintechs, neobanks, and digital wallets across Latin America and Europe that want to offer their users the ability to buy, sell, send, and hold crypto assets.
What problem does it solve? Building crypto infrastructure means dealing with local payment rails, KYC/AML, custody, and liquidity — all at once. Lirium handles all of it through a single API so your team can focus on your product.
How fast can you integrate? A sandbox account, a key pair, and a few API calls are all you need. Most integrations go from zero to first transaction in under a day.
Local Fiat On/Off-Ramps
One of Lirium's key differentiators is native support for local payment rails across the regions we serve:
| Region | Deposit Rails | Withdrawal Rails |
|---|---|---|
| Latin America | Local instant-transfer rails (e.g. CVU, CLABE) | Local bank account rails (e.g. CBU, CLABE, Alias) |
| Europe | Local bank transfer rails | Local bank transfer rails |
How it works in practice: A user sends fiat from their bank app to the local deposit account assigned to them by your platform. Within seconds, Lirium detects the deposit and credits the equivalent local stablecoin to the user's account — no manual steps required.
This flow works in reverse too: a user requests a withdrawal, and Lirium converts their stablecoins back to fiat and sends it to their registered bank account.
See Fiat Instructions for the full integration guide, or jump straight to the Recipes for end-to-end examples.
