Two big open lists of free APIs and public datasets, turned into one Obsidian vault: every entry has its own note, sorted by what a small business can do with it, with a link check, ready-made views, plain-words recipes and ten source guides.

One note per API: key or no key, HTTPS, browser-friendly or not, its link check and what it’s good for.
One note per public dataset, by topic, with its link check.
Seven lists read through by hand: find customers, market research, real estate, food and drink, finance data, content and SEO, selling online.
Hand-picked sources at the top of every list, for when you don’t know where to begin.
Find local customers, research a market before you open, real estate numbers, an app demo with no-key APIs, and more.
OpenStreetMap, data.gov, FRED, OpenAlex, GDELT, Open Food Facts and more: what each is, uses, an example, limits and credit lines.
An API trial log and a data project brief, with filled-in fictional examples.
Record where a key lives, never the key itself.
The entries are real APIs and datasets, as checked on 2026-10-13. The project and trial examples are fictional.
A free, smaller edition you can keep and share. If it helps, the full vault picks up where it stops.
The ten featured-source guides, one recipe and 50 no-key APIs that answered our link check. No email needed.
What is Obsidian?
A free note-taking app for Windows, Mac, Linux, iPhone, iPad and Android. Your notes are plain files on your own device, not in someone else’s database. Get it at obsidian.md.
Do I need plugins or coding?
No. Everything uses Obsidian’s built-in features (Bases, templates, daily notes), so it works with Restricted mode on, works on your phone, and keeps working when Obsidian updates.
What exactly do I get?
A ZIP with the complete vault: templates, ready-made views, guides, and fictional sample data you can clear from one list. Open the folder in Obsidian and the Home page appears.
Where does the data come from?
Two open lists on GitHub, public-apis and awesome-public-datasets, both MIT licensed; their notices are in the vault. We added the link check (2026-10-13), the business-use sorting, the views, the recipes and the source guides.
Do the APIs cost anything?
Many are free and some need a free key or account; the notes say which. Each provider sets its own terms, limits and credit lines, so read them before you build on a source.
Can I change it?
Yes, all of it. Rename statuses, add fields, delete what you don’t need. It’s yours to keep.
What if it isn’t right for me?
Email us within 14 days of buying and we’ll refund you. No form, no argument.
Does it work on my phone?
Yes. Use any sync you like (Obsidian Sync, iCloud or a free option); a guide inside compares them.
Is my data private?
Yes. The vault runs on your devices and we never see your notes. It’s designed to never hold passwords or ID numbers.
Do I get updates?
Yes, free for 12 months: re-download from the link on your purchase page.
