How this service works
Pay-per-call data tools for developers and AI agents: company registers, documents, tenders, rates and on-chain facts as MCP tools, x402 endpoints and Apify Actors.
Output
Returns a JSON object with a results array where each entry includes the target URL, HTTP status, final (redirected) URL, a list of detected technologies each with name, category, evidence sources, and confidence level, plus aggregate counts of succeeded and failed checks and a timestamp. A note is included warning that client-side or lazy-loaded technologies may not be detected.
Example use cases
Competitor tech stack reconnaissance
“I want to know what technologies my competitor acme.com is using — web server, frontend framework, CMS, anything you can detect from their public site.”
Bulk tech stack audit of prospects
“I have a list of potential clients — can you check what tech stacks these five domains are running: shopify.com, bigcommerce.com, woocommerce.com, magento.com, and squarespace.com?”
Verify framework before integration
“Before we build our integration, can you tell me if api.hubspot.com is running on any known frameworks or uses a specific web server that we should know about?”
Technical details
Endpoint
GEThttps://api.ambolt.dev/v1/tech-stack-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, lightweight technology fingerprinting of public websites based on HTTP headers and static page content. Ideal for competitive intelligence, lead enrichment, or pre-integration audits where you need to identify web servers, frameworks, and CDNs without full browser rendering. Supports batch lookups of up to 20 URLs per call at $0.005 USDC per call, making it cost-effective for bulk analysis.
Side effects
- URL is unreachable or returns a non-200 status — entry marked with ok:false
- Private or intranet URLs that are not publicly accessible will fail to resolve
- Technologies loaded only via JavaScript execution or on secondary pages will not be detected
- Exceeding the 20-URL limit on the urls array will cause a validation error
- Malformed or non-HTTP/HTTPS URLs rejected by schema validation
