# AgentUtility Tech Stack Detect

> AgentUtility Tech Stack Detect is a paid API for AI agents from x402.agentutility.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Detects and identifies the technology stack (CDN, hosting, framework, etc.) of a given website URL

## Facts

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 agentutility-tech-stack-detect-12bf5a1a -d '<json body>'
```

Example prompt: Can you scan https://stripe.com and tell me what CDN, hosting provider, and frontend framework they're using — with confidence levels for each detection?

## When to prefer this

Use this endpoint when you need to programmatically identify the technology stack of any public website — especially for competitive research, vendor auditing, or pre-integration discovery. Prefer this over manual inspection or browser extensions when operating in an automated agent pipeline that needs structured, machine-readable output with confidence scores.

## Known failure modes

- URL is unreachable or returns non-200 — detection may return empty or partial results
- Private/intranet URLs cannot be fetched — returns error or zero detections
- Obfuscated or heavily custom stacks may yield low-confidence or incomplete detections
- Malformed URL input causes a validation error
- Payment failure via x402 prevents the request from being processed

## How this service works

Paid x402 endpoints organized into product clusters. USDC-settled on Base. MCP-callable. ERC-8004 identity registry agentId 47167.

## Output

Returns a JSON object with the resolved final URL, a categorized map of detected technologies (CDN, hosting, framework, etc.), a flat list of individual detections each with name, category, and confidence level (high/medium/low), and a total detection count.
