How this service works
Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.
Output
Returns a JSON object containing a 'detected' array of technology names identified from the website (e.g. ['WordPress', 'Nginx', 'PHP']), plus 'server_header' and 'powered_by_header' string fields extracted from HTTP response headers (either a string value or null if not present).
Example use cases
Competitor tech stack research
“Can you figure out what technology stack https://shopify.com is built on? I want to know the web server, any frameworks, and whatever headers reveal about their setup.”
Security audit pre-check
“Before I run my security audit, detect what server software and platform https://targetclient.com is using so I know what vulnerabilities to look for.”
Developer stack verification
“I just deployed my site at https://myapp.io — can you confirm it's showing Nginx in the server header and not leaking any 'X-Powered-By' info?”
Technical details
Endpoint
GEThttps://api.geekvault.dev/web-tools/v1/tech-detect?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, no-signup, pay-per-call technology fingerprinting check on any public URL — especially useful for one-off lookups during competitive research, security audits, or dev verification where subscribing to a full-featured tool like Wappalyzer's API is overkill. Ideal for agents that need lightweight tech detection without managing API keys.
Side effects
- Invalid or unreachable URL returns an error — ensure the URL is well-formed and the target site is publicly accessible
- Some sites block automated requests or hide headers, resulting in an empty 'detected' array and null headers
- Sites using CDNs or reverse proxies may only expose proxy-level headers, obscuring the real backend stack
- Timeouts may occur for slow-responding or geographically restricted URLs
