## 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 website-tech-stack-detector-api-2980def0
```

Example prompt: Can you detect what tech stack allbirds.com is running — specifically what ecommerce platform, payment processors, analytics tools, and ad pixels they use?

## When to prefer this

Use this endpoint when you need to quickly fingerprint a website's technology stack for lead enrichment, competitive intelligence, or sales prospecting without manually inspecting page source. Ideal when you need structured signals like ecommerce platform, payment provider, and ad pixel presence in a single lightweight call. Prefer over manual scraping or full browser automation when a fast, affordable per-domain lookup is sufficient.

## Known failure modes

- Domain is unreachable or returns non-200 — may return empty or partial results
- Homepage uses heavy JavaScript rendering that blocks static analysis — some tools may go undetected
- Domain resolves but has no meaningful tech signals — returns empty arrays
- Invalid or malformed domain input — likely returns an error
- Rate limiting or x402 payment failure — request blocked before processing

## How this service works

Exact EVM address, calldata, Uniswap V2/V3 and impermanent-loss math. Pay per call in USDC on Base via x402.

## Output

Returns a JSON object with the domain, detected ecommerce platform (e.g. Shopify), list of payment processors (e.g. Stripe), analytics tools (e.g. Google Analytics), boolean flags for has_ecommerce and has_ad_pixel, and any detected CDN or support chat software.
