| Concept | What it is | Key points |
|---|---|---|
| FX Quotes | A price offer to exchange an amount from USD to BRL. | Not linked to a sender. Fixed USD or fixed BRL. One price for PREFUNDED and CREDIT. Short validity, used once. usage = REMITTANCE (default) for a withdrawal, or INVENTORY to create an Inventory Lot. Does not check the sender, reserve limit or contract FX. |
| Withdrawals | The operation that sends money from a sender to a beneficiary in Brazil. | Informs sender, beneficiary, purpose, relationship and funding mode. PREFUNDED and CREDIT use a quote (quoteId). INVENTORY uses a lot (funding.inventoryId), the BRL amount and senderQuote, with no quoteId. Creating a withdrawal creates a remittance. |
| Remittances | The full operation that sends money from a sender to a beneficiary. | Created by a withdrawal; type WITHDRAWAL. One lifecycle status, plus a sub-status for FX, funding, payout and settlement. |
| Senders | The MSB’s customers in the US who start and pay for remittances. | Individual (18+) or business. Compliance level LEVEL_0 to LEVEL_3 defines whether and how much they can send in 24h, 30d and 180d. |
| Beneficiaries | The people or companies in Brazil who receive the BRL. | Registered with address and relationship type. One or more Pix keys, each screened before use. |
| Funding | How a remittance is paid for before the Pix is sent. | PREFUNDED uses USD the MSB already holds in the US, paid before the Pix. CREDIT advances the BRL through the LB Pay credit line and creates an obligation to repay. INVENTORY uses FX volume contracted in advance in an Inventory Lot. |
| Inventory Lots | FX volume contracted in advance by the MSB, with a fixed rate, volume and validity. | Created with POST /v1/inventories from an INVENTORY quote; each call creates a new, independent lot. Creates a USDC payment promise. Balances total, available, reserved and used, in BRL and USD (total = available + reserved + used). Status ACTIVE, DEPLETED, EXPIRED. Used by withdrawals with funding.mode = INVENTORY. |
| Wallets | Balances linked to the MSB’s remittances. | USD Wallet is the MSB’s prefunded USD balance in the US. BRL Wallet is real balance in Brazil. Ledger, available, reserved and pending balances. |
| Settlements | Daily batch with what the MSB pays for credit used. | One batch per due date: one amount and one payment per day. Status open, closed, due, overdue, completed. Counterpart is LB Pay. |
| Compliance | Controls applied to senders, beneficiaries and remittances. | Runs automatically: KYC levels, beneficiary approval, sanctions and AML screening. Can place a remittance ON_HOLD. There is no compliance API: the MSB sees the result in the status of the sender, beneficiary and remittance. |
