Free badge · Works anywhere HTML renders

Embed your Signal Score anywhere

Drop one line of code on your website, GitHub README, or email signature and show your live Signal Score. The Signal Engine re-scores automatically so the badge always reflects your current standing.

Try it first with your domain

Option 1: SVG image (works everywhere)

A single image URL. Works in Markdown, HTML, GitHub READMEs, GitLab, email signatures, and any place that renders an <img> tag. Zero JavaScript required.

<a href="https://inbxr.us/?domain=yoursite.com">
  <img src="https://inbxr.us/api/badge/yoursite.com.svg" alt="InbXr Signal Score" />
</a>

For GitHub README (Markdown):

[![Signal Score](https://inbxr.us/api/badge/yoursite.com.svg)](https://inbxr.us/?domain=yoursite.com)

Option 2: JavaScript snippet (auto-styled, clickable)

A single script tag. Auto-fetches the latest score and renders a clickable badge in place. Best for websites you control where you want the visual polish of a styled HTML badge instead of a static image.

<script src="https://inbxr.us/badge.js" data-domain="yoursite.com"></script>

Option 3: Raw JSON API

For Chrome extensions, custom integrations, or dashboards. Returns the current score, grade, and metadata as JSON. CORS-enabled so you can call it from any website.

curl https://inbxr.us/api/badge/yoursite.com.json
{
  "ok": true,
  "domain": "yoursite.com",
  "score": 94,
  "grade": "A",
  "badge_url_svg": "https://inbxr.us/api/badge/yoursite.com.svg",
  "report_url": "https://inbxr.us/?domain=yoursite.com"
}

Why embed the badge

Your Signal Score is a credibility signal. A visible A-grade badge on your website tells visitors you take deliverability seriously. It's a trust anchor, a talking point, and a public commitment to keep the score high.
