# Paj API

## Docs

- [Get rates](https://docs.paj.cash/api-reference/get-rates.md): Returns the latest active onramp and offramp rates for the given target fiat currency. Rates already include the business fee applied to the API key.
- [Register a bank account](https://docs.paj.cash/api-reference/register-bank-account.md): Registers a bank account for the API key’s business using a bank code and account number.
