Stack Scan

POST https://api.jobspipe.dev/v1/stack/scan

Given a domain, returns the technologies it serves - frontend frameworks, analytics, CDNs, payment processors, and SaaS widgets - detected from its live homepage. Results are cached, and a domain's history keeps a new entry only when its stack changes. Requires authentication.

Request

The body is a JSON object with a single required domain.

curl https://api.jobspipe.dev/v1/stack/scan \
  -H "Authorization: Bearer jp_live_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{ "domain": "stripe.com" }'

import requests

resp = requests.post(
    "https://api.jobspipe.dev/v1/stack/scan",
    headers={"Authorization": "Bearer jp_live_your_key_here"},
    json={"domain": "stripe.com"},
)
resp.raise_for_status()
result = resp.json()
for tech in result["detected"]:
    print(tech["name"], "-", ", ".join(tech["categories"]))

const resp = await fetch("https://api.jobspipe.dev/v1/stack/scan", {
  method: "POST",
  headers: {
    Authorization: "Bearer jp_live_your_key_here",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({ domain: "stripe.com" }),
});
const result = await resp.json();
for (const tech of result.detected) {
  console.log(tech.name, "-", tech.categories.join(", "));
}

Response

A 200 response describes the domain's current stack:

• detected - an array of detected technologies. Each has name, slug, categories, a confidence score (0-100), an optional version, and metadata such as website, saas, and oss.
• scanned_at - when this stack snapshot was recorded. A new snapshot is stored only when the detected stack changes, so this is effectively "the stack has been this way since".
• http_status / render_path - how the domain responded and which fetch path produced the result.

  "render_path": "curl_cffi",
  "detected": [
    {

      "saas": false,
      "oss": true
    },

      "name": "Cloudflare",
      "categories": ["CDN"],
      "confidence": 100,

      "website": "https://www.cloudflare.com",
      "saas": true,
      "oss": false
    }
  ]
}

A reachable domain with no recognizable technologies returns http_status: 200 and an empty detected array. A domain the scanner could not reach returns http_status: 0.
