# Liquidity Pool

API of the Carbon Pool: clients, their invoices, employees and Individual Consumptions, carbon pool purchases, and Spending Capacity balances.

**Authorization.** Every call carries the `hash` parameter with your API key.

**Answers.** The endpoints answer with the `{message, success, data, operations_count}` envelope; a refused call answers HTTP 400 with `success: false`. The [Balance](/tri-doc/liquidity-pool/balance.md) section follows conventions of its own, described on its page.
