The API Marketplace gives your team a single place to discover, compare, and subscribe to API products — from identity verification to financial event streaming. Navigate to your team workspace and select **APIs** in the sidebar to open the marketplace. Once you subscribe to a plan, you receive an API key that authenticates requests to that product. ## Built-in API products Three API products come pre-bundled with every Palladium AI workspace. You can subscribe to any of them directly from the marketplace without any additional configuration by your platform owner. | Product | What it does | | --------------------- | -------------------------------------------------------------------------------------------------------------------------------- | | **Risk Score API** | Returns a repayment-risk score for a member or loan application, helping your team make data-informed credit decisions. | | **KYC Verify API** | Runs identity-verification checks against submitted member documents, supporting compliant onboarding flows. | | **Ledger Events API** | Streams structured financial events from your ledger — deposits, withdrawals, loan disbursements, and repayments — in real time. | ## Custom API products Your platform owner can publish additional API products through the admin console. These **custom products** appear in the same marketplace catalog alongside the built-in products, but are marked with a **Custom** badge so you can identify them at a glance. Custom products are configured entirely by your platform owner. They may target specific integrations, regional data sources, or proprietary scoring models relevant to your cooperative's operations. Each custom product can expose multiple plans at different price tiers — review the plans table for a product to see what's available before subscribing. ## Plan details Every API product exposes one or more subscription plans. Expand a product in the marketplace to reveal its **plans table**. Each row in the table describes one plan across the following columns: | Column | Description | | ---------------- | ------------------------------------------------------------------------------------------------- | | **Plan Name** | A short label for the tier, such as "Starter" or "Pro". | | **Price** | The monthly cost of the plan in Kwacha (K). | | **Quota** | The maximum number of API calls your team can make per calendar month. | | **Rate Limit** | The maximum number of API calls allowed per minute at any point in time. | | **Billing Mode** | One of **Free**, **Fixed**, or **Metered** — indicating how charges are calculated for this plan. | When you find the plan that fits your team's usage needs, click **Select → billing** on that row to proceed to checkout. Step-by-step guide to choosing a plan and completing your subscription in the marketplace. Find, copy, and use your API key to authenticate requests after subscribing.
