How this service works
URL-to-clean-markdown extraction API, on-demand broken-link scan API, pre-deploy link audit API, DNS health audit API, llms.txt / AI-crawler audit API, spec-linted llms.txt audit API, email-deliverability (SPF/DKIM/DMARC) audit API, PDF-to-markdown conversion API, technology-stack fingerprinting API, security-headers audit API, and PDF metadata-intel API for coding agents. Paid per call in USDC via x402 on Base.
Output
Returns a JSON object with ok status, the final resolved URL, a checkedAt timestamp, a counts summary (number of categories and technologies found), a categories map grouping technologies by type (e.g. CMS, Web Server, JavaScript Library) with version strings, and a technologies array where each entry includes name, version, category, evidence string, and confidence level (high/medium/low). Also includes the atomic USDC amount charged.
Example use cases
Competitor technology reconnaissance
“I want to know what tech stack TechRival.io is running — what CMS, JavaScript libraries, and web server they use, with versions if you can find them.”
Pre-sales tech discovery for agencies
“Before we pitch to this prospect, can you fingerprint https://www.prospectcompany.com and tell me if they're on WordPress or something else, so we know how to tailor our migration offer?”
Security audit stack identification
“Run a technology fingerprint on https://staging.internalapp.com and tell me every framework and library version you detect — I need to check for outdated dependencies before we go live.”
Technical details
Endpoint
POSThttps://x402-extract-service.onrender.com/techstackWhen to prefer
Use this endpoint when you need structured, evidence-backed technology identification for any public website, including CMS version, web server type, and JS library detection with confidence scores. It is ideal for competitive intelligence, pre-sales research, security audits, and automated pipeline enrichment. Prefer this over generic scraping when you specifically need categorized tech-stack data with version and evidence fields rather than raw page content.
Side effects
- Invalid or non-public URL returns error response
- URL is unreachable or times out — no technologies returned
- Site behind authentication or bot-blocking may yield sparse or empty results
- Dynamic single-page apps may not expose server-side stack signals in HTML
- Payment failure via x402/USDC results in 402 response before processing begins
