Query the Profit Lab 360 niche index programmatically — demand, saturation and trend scores for hundreds of POD niches via a simple REST API.
The public niches API exposes the same data that powers the Profit Lab Index: niche slug, name, category, demand score, saturation score, 7-day trend, average price and top keywords. It is a plain REST endpoint that returns JSON, so you can pull POD niche data into a spreadsheet, a dashboard, or your own tooling.
There is also an embeddable widget if you want the ranked niche list on your own site without writing code. Both are free for reasonable, attributed use.
Each record contains the niche slug and display name, its canonical category (professions, hobbies, humor, sports, seasons, causes, aesthetics or fandoms), a demand score from 0 to 100 measuring search and buying interest, a saturation score from 0 to 100 measuring how crowded the niche already is across POD marketplaces, the 7-day trend as a percentage, the average observed selling price, and the top keywords buyers actually search.
Results are ordered by demand by default and support limiting and category filtering, so a single call can return the top niches for one category.
Pull the ranked list into a spreadsheet to plan a design calendar, feed it into your own dashboard next to your sales data, or watch the 7-day trend field to catch niches while they are still climbing.
Scores are refreshed by AI agents from live marketplace and web search signals, so responses reflect current conditions rather than a static list. Cache responses for a day and you will never be behind the data.
The widget renders the same ranked niche list as a lightweight iframe you can drop into a blog post or resource page — no API key, no build step. It is a fair way to give your audience live Print on Demand niche data with attribution back to the Profit Lab Index.
