How this service works
Pay-per-call web tools for AI agents. No API keys: pay per request in USDC on Base via x402.
Output
Returns a JSON object containing the detected server software (e.g. 'Vercel', 'nginx'), the generator or CMS if identifiable, and an array of detected technologies and frameworks (e.g. ['Next.js', 'React', 'Vercel']) for the submitted URL.
Example use cases
Competitor tech stack reconnaissance
“Can you check what technologies https://linear.app is running — I want to know their server, front-end framework, and any notable libraries.”
Verify site migration to new stack
“We just migrated our site to Next.js — can you confirm that https://mycompany.com is now being detected as Next.js and Vercel?”
Research CMS powering a blog
“What CMS or generator is powering https://www.smashingmagazine.com? I want to know if it's WordPress, Gatsby, or something else.”
Technical details
Endpoint
GEThttps://x402-web-tools.onrender.com/api/tech-detect?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a no-API-key, pay-per-call solution to identify the technology stack, server, or framework of any public website. Ideal for one-off lookups or agent workflows where provisioning API credentials is impractical. Prefer over browser-based Wappalyzer or BuiltWith integrations when you need a lightweight HTTP call with micropayment billing via x402 on Base.
Side effects
- Non-public or private URLs return an error or empty result
- Highly obfuscated or security-hardened sites may return minimal or no technology signals
- Invalid or malformed URLs cause a request validation error
- Timeout if the target site is slow to respond
- Sites behind WAFs may block the detection probe, yielding incomplete results
