How this service works
Verified B2B lead packs and per-lead enrichment lookups for agents. $0.01 per lookup or pack (demand probe). USDC on Base via x402. No account, API key, or subscription.
Output
A JSON object containing the queried domain, a receipt confirmation, an array of detected technology signals, an array of identified technologies (e.g. ['nginx','wordpress']), and the raw server header string.
Example use cases
Prospect tech stack qualification
“Before I reach out to acme.com, can you check what technology stack they're running — specifically whether they use WordPress, Shopify, or any other CMS?”
Competitive intelligence research
“I'm building a list of companies using nginx. Can you fingerprint hubspot.com and tell me their server and tech stack so I can see if they fit the profile?”
Lead enrichment before outreach
“I have a lead at notion.so — can you pull their tech stack fingerprint so I know what infrastructure and frameworks they're using before I pitch them?”
Technical details
Endpoint
GEThttps://scout-packs-production.up.railway.app/tech-stack?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, per-domain technology fingerprinting for B2B lead enrichment or sales intelligence workflows, especially when you want pay-per-call pricing with no API key or subscription. Prefer it over heavier enrichment platforms when all you need is tech stack detection rather than full firmographic data.
Side effects
- Domain is unreachable or returns no HTTP response — technologies array may be empty
- Domain uses aggressive bot-blocking — signals may be incomplete or misleading
- Unrecognized or novel tech stack — technologies array returns empty even if stack exists
- Invalid or malformed domain input — request fails validation
- Payment failure via x402 — call is rejected before fingerprinting occurs
