Public APIs

Conditional free route directory

Researched from public pages — no submission was run · sources read 2026-09-25. Rules change — recheck the platform's own pages before submitting.

What the free route requires

A free plan exists but carries a 4-5 week review queue ('Start with the free plan and upgrade to Pro anytime' per the submit-page FAQ)
Pro plan ($99 one-time) skips the queue: 24-hour review, live within 72 hours, dedicated detail page, priority support

Product must be a public API: legit, documented, 'not obvious spam or scam'; they reserve the right to reject low-quality submissions
Form requires: API name, website/docs URL, category, 1-2 line plain-English description, contact email

Open https://publicapis.io/submit (the batch's public-apis.io domain rendered only a JS shell; the operational site is publicapis.io)
Select the free plan or Pro plan on the form
Fill API name, docs URL, category, description, contact email
Free: wait in the 4-5 week queue. Pro: complete $99 payment, ~24h review, live within 72h
Verify listing appears in the /apis directory

Domain discrepancy: the catalog entry is public-apis.io (JS-only render) while the working directory and submit form live at publicapis.io — treat them as the same property but verify
The submit page defaults to the Pro plan UI — look for the free-plan option before paying
Pro payment is 'secure redirect' based; 30-day money-back guarantee stated
Do not confuse this with the unrelated github.com/public-apis/public-apis GitHub list, which has its own PR-based contribution rules

The API appears in the publicapis.io API directory under its category (Pro listings additionally get a dedicated detail page)

Whether public-apis.io and publicapis.io are officially the same operation or a redirect/alias
Whether the free plan listing is dofollow
Whether the free tier gets any detail page or just a row entry
