How to submit to PublicAPIs.io

  1. Open the PublicAPIs.io submission page

    This is the page makers use to add a product.

  2. 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.

  3. Fill in the form carefully

    Pick the most specific category the form offers and write the description for the people who browse PublicAPIs.io (Developers looking for free or public APIs to build with), not for search engines.

  4. 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 PublicAPIs.io

  • Only submit if the API is documented and legitimate; the FAQ says spam or scam APIs are rejected.
  • The free route is slow (the site quotes 4-5 weeks), so pay for Pro only if timing matters.
  • Pick the closest existing category and write a one or two line plain-English description.

From PublicAPIs.io’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 PublicAPIs.io worth it?

Good for your SEO foundation

PublicAPIs.io 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: 41 (moderate). That's the strength of links to the whole site, not a promise about what your listing passes on.
  • No Tranco rank on record, so we can’t say how much traffic it gets.
  • 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.
