Tree-shakeable imports

The root Brex class wires up all ten Brex APIs. If bundle size matters (browsers, edge functions), import only what you use — each subpath is an independent module graph, so the other nine APIs never enter your bundle (about 3.5 kB min for a single API).

import { createPaymentsClient } from 'brex/payments';

const payments = createPaymentsClient({ token: process.env.BREX_TOKEN! });
const vendors = await payments.vendors.list({ name: 'Acme' });

Every subpath also exports its resource classes (for composing with a shared BrexCore) and all of its schema types:

import type { VendorResponse, CreateVendorRequest } from 'brex/payments';
import type { ExpandableExpense } from 'brex/expenses';

Available subpaths

Each subpath maps to one vendored OpenAPI spec:

Subpath	Client factory
brex/accounting	createAccountingClient
brex/budgets	createBudgetsClient
brex/expenses	createExpensesClient
brex/fields	createFieldsClient
brex/onboarding	createOnboardingClient
brex/payments	createPaymentsClient
brex/team	createTeamClient
brex/transactions	createTransactionsClient
brex/travel	createTravelClient
brex/webhooks	createWebhooksClient
