# Tech Detect — Website Technology Stack Detection (TYPO3 specialization)

> Tech Detect — Website Technology Stack Detection (TYPO3 specialization) is a paid API for AI agents from stack.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-12).

Detects the technology stack of a given domain/URL, returning technologies found with confidence scores and evidence, paid per-call via x402 USDC microtransaction

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tech-detect-website-technology-stack-detection-typo3-specialization-a5541b67 -d '<json body>'
```

Example prompt: What's the full technology stack behind stripe.com — CMS, frameworks, analytics, CDN, everything you can detect with confidence scores?

## When to prefer this

Choose this endpoint when you need pay-per-call technology detection without signup or API keys, especially in agentic workflows where you want to pay only for what you use via USDC microtransactions. It is well suited for one-off lookups, lead enrichment pipelines, or competitive intelligence tasks where batch subscriptions are overkill. The optional 'previous' field makes it efficient for change-monitoring use cases by supplying prior results for diffing.

## Known failure modes

- URL is unreachable or returns no HTTP response — no technologies returned
- Domain blocks fingerprinting signals — low confidence or empty results
- Invalid URL format in input — request rejected with validation error
- Payment via x402 fails or insufficient USDC balance — 402 response, no detection performed
- Rate limiting or network timeout on target domain — partial or empty results

## How this service works

Domain in, technology stack out. Confidence and evidence for every hit. Pay per call in USDC over x402. No signup, no API key.

## Output

A structured list of detected technologies, each with its name, category (e.g. CMS, CDN, JavaScript framework), version where identifiable, a confidence score, and supporting evidence. Coverage spans frontend libraries, backend platforms, CMS, analytics, CDN, and more.
