# Strale Tech Stack Detect

> Strale Tech Stack Detect is a paid API for AI agents from api.strale.io, paid per call via x402, $0.0324/call, status unknown (last checked 2026-09-15).

Detects the technology stack (frameworks, CMS, analytics, CDN, etc.) used by any website given a URL or domain

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 strale-tech-stack-detect-a10b2c77
```

Example prompt: Can you detect what technology stack powers stripe.com — I want to know their CMS, frontend framework, analytics tools, and CDN?

## When to prefer this

Choose this endpoint when you need structured, auditable tech-stack detection with cryptographic provenance for compliance or trust workflows. It suits agents doing competitive intelligence, vendor due diligence, sales lead qualification, or security assessments where the audit trail matters. Prefer it over generic scraping tools when you need categorical technology classification (CMS, framework, CDN) rather than raw HTML.

## Known failure modes

- URL or domain is unreachable or returns non-200 status — detection may be incomplete
- Private or heavily obfuscated sites may yield minimal fingerprinting data
- Neither url nor domain query parameter provided — returns validation error
- Rate limiting or network timeouts when the target site is slow to respond
- Target site actively blocks fingerprinting crawlers

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns a structured JSON payload identifying the technologies detected on the target website, including frontend frameworks, CMS platforms, analytics tools, CDN providers, JavaScript libraries, server software, and other stack components. Each response includes a cryptographic audit record with chain hashing for provenance verification.
