## 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 builtwith-technology-trends-via-locus-x402-0aec63cc -d '<json body>'
```

Example prompt: Can you pull the adoption trends for Shopify from BuiltWith — I want to see how its usage across the web has been changing over time?

## When to prefer this

Use this endpoint when you need time-series or historical trend data showing how a specific technology's adoption has changed across the web — ideal for market research, competitive benchmarking, or investment analysis. Prefer this over the domain-lookup or tech-detection siblings when the goal is aggregate trend insight rather than profiling a specific website.

## Known failure modes

- Unknown or unrecognized technology name returns empty data or error
- Misspelled TECH parameter yields no results
- Rate limiting or payment failure blocks the request
- Technology name ambiguity (e.g. 'React' vs 'React Native') may return unexpected results
- Network timeout from upstream BuiltWith API

## How this service works

Technology profiling for websites — detect tech stacks, find sites using specific technologies, discover domain relationships, trends, and competitive intelligence across 100M+ websites.

## Output

Returns a JSON data object containing historical adoption trend data for the specified technology — likely including time-series usage counts or percentage share across the BuiltWith dataset of 100M+ websites — along with payment metadata confirming the $0.035 USDC charge and a request ID for status tracking.
