What is an API Product?

An API product is the listing customers see and subscribe to on api.market. Your API source is the technical connection to your backend; the product is the public page — with a name, description, pricing, and the endpoints you choose to expose.

🔄 Source vs. product

	API Source	API Product
What it is	Your OpenAPI spec + backend connection	The marketplace listing
Who sees it	Only you	Customers on api.market
Contains	All endpoints from your spec	Selected endpoints, pricing, and copy

You always import a source first, then create one or more products from it.

🛠️ Create a product

You can start two ways:

• From API Sources, click Create Product on the green banner.

• From Manage APIs → API Products, click Create Product.

🔗 Choose your product slug

The API prefix / product slug becomes part of the URL customers call. Use lowercase letters, numbers, and hyphens, and keep it short and descriptive.

⚠️ Important: You cannot change the slug after the product is created, so choose it carefully.

📝 Fill in the product details

After creating the product you land on Product Settings. A publishing checklist at the top tracks what is left to do:

Step	Requirement
1. Product details	Title, subtitle, and description
2. Pricing plans	At least one plan
3. Submit for review	Unlocks after steps 1 and 2

Fill in:

• Title — a clear, catchy headline for your product page.

• Subtitle — a one-line summary (max 160 characters).

• Description — the full product page, written in markdown. Add features, examples, and FAQs, or click Generate with AI for a starting draft.

💡 Tip: Use Preview Product (top right) to see exactly how your listing looks to customers, and click Save as you go.

When your details are filled in, step 1 of the checklist turns green.
