How to submit to Public APIs

  1. Open the Public APIs submission page

    This is the page makers use to add a product.

  2. Create an account

    Public APIs asks you to sign up before you can submit.

  3. Have your assets ready

    Name, tagline, description, logo and screenshots. The checklist below covers what to prepare so you can fill the form in one go.

  4. Fill in the form carefully

    Pick the most specific category the form offers and write the description for the people who browse Public APIs (Developers looking for APIs to integrate), not for search engines.

  5. Wait for review

    A person reviews submissions, so it can take a while. Once it’s live, check the link on your listing points to the right page.

Tips for Public APIs

  • The API must be self-serve and publicly documented: no waitlists or contact-sales gates
  • Paid and freemium APIs are allowed
  • Docs must make auth and CORS behaviour clear
  • Edit README.md only; the /db folder is generated

From Public APIs’s own guidelines and pages, in our words.

What to prepare

The basics every directory asks for, plus what matters most for developer tool directories.

  • Product name and a one-line tagline (about 60 characters)
  • A short description (1–2 sentences) and a longer one (a short paragraph)
  • Square logo, at least 256×256 px, PNG or SVG
  • 2–3 screenshots at a consistent size
  • The exact page you want the link to point to
  • Pricing model (free, freemium or paid) and a contact email
  • Links to your docs and a quick-start or install command
  • Your GitHub or GitLab repo, if public
  • Supported languages, frameworks and platforms
  • Pricing for the API or hosted tier, including free limits

Is Public APIs worth it?

Good for your SEO foundation

Public APIs reviews listings by hand and the listing link we inspected was followed. That combination is what makes a directory link worth having for a new site.

  • Domain Rating by Ahrefs: 46 (moderate). That's the strength of links to the whole site, not a promise about what your listing passes on.
  • Tranco rank #2,293,978: a small site, outside the top 1 million.
  • A person reviews submissions, so expect a wait and a real quality bar.
  • There’s a free option. Start free and only pay for upgrades if the traffic justifies it.

This verdict is worked out from the facts above with fixed rules (link type, review, price, Domain Rating by Ahrefs, Tranco rank), not paid for. The directory has no say in it.
