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.

🛠️ 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:

Requirement

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.
