```

Example prompt: Can you detect what technology stack example.com is running — like what CMS, CDN, server, and JavaScript frameworks they use?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call technology fingerprint of a website without setting up accounts or API keys. Ideal for competitive research, pre-engagement security assessments, or vendor evaluations where you need CMS, CDN, server, and framework details in a single call billed in USDC on Base.

## Known failure modes

- Invalid or unreachable URL returns an error or empty signals
- Site with heavy obfuscation may return zero or incomplete signals
- Rate limiting or bot protection on target site may block the scan
- Malformed input schema (missing required fields) returns a 4xx error
- Payment failure via x402 prevents the call from completing
