How this service works
Open job postings read first-hand from the applicant-tracking system behind a company's careers page: Greenhouse, Ashby, Lever or Workable. Includes a directory of 8532 company job boards, because none of the vendors publishes one. Salaries are parsed into numbers where the employer publishes them and refused where ambiguous. No personal data.
Output
Returns a JSON object containing the target domain, the final resolved URL after redirects, HTTP fetch status, a list of detected technologies (each with name, version, evidence type, categories, and confidence score), a list of CDN providers, and MX host records.
Example use cases
Competitor tech stack research
“What technologies is notion.so using on their website? I need to know their CDN, front-end framework, analytics tools, and any marketing software you can detect.”
Sales prospecting enrichment
“I'm prospecting a list of SaaS companies — can you tell me what tech stack linear.app is running? I want to know if they use Cloudflare, what their MX host is, and any detectable product analytics tools.”
Security and infrastructure audit
“Analyze the tech stack on gitlab.com for me — specifically flag any CDN or DDoS protection, infer their email provider from the MX records, and list every technology you can detect with confidence above 90%.”

Endpoint
GEThttps://ats-jobs-api.groundtruthtools.workers.dev/x402/v1/tech-stack?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to identify the software, CDN, and email infrastructure behind a specific domain without manual inspection. It is particularly valuable for sales intelligence pipelines, competitive research, and security audits where you need structured, machine-readable tech stack data with per-technology confidence scores. Prefer this over generic web scrapers when you specifically want technology fingerprinting with categorized output rather than raw HTML content.
Side effects
- Domain unreachable or returns non-200 status — fetch_status will be non-ok and technology list may be empty
- Domain redirects to login wall or bot-protection page — technologies detected may be limited to edge/CDN layer only
- Ambiguous or private domain — no results or very low confidence scores
- min_confidence filter too high — returns empty technology array even when detections exist
- Malformed or missing URL query param — request rejected with validation error
