## 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 orthogonal-technology-stack-lookup-af98f9cc -d '<json body>'
```

Example prompt: What's the tech stack for stripe.com? I want to know if they're using any React-based frameworks or Salesforce.

## When to prefer this

Choose this endpoint when you need to identify what software technologies a company is running based solely on their domain. It is especially useful for B2B sales prospecting, competitive intelligence, and lead qualification workflows where knowing a prospect's existing tech stack helps personalize outreach or filter lists. The credit-only-on-results pricing model makes it cost-efficient for bulk enrichment pipelines where many domains may return no data.

## Known failure modes

- Domain not found or not crawlable — returns empty results at no charge
- Invalid domain format — may return an error or empty response
- Technology filter provided but none of the filtered technologies are present — returns empty match
- Rate limiting or credit exhaustion — may return an authorization or quota error
- Domain exists but has no detectable technologies — returns empty results at no charge

## How this service works

Get the technology stack for a company by domain. 1 credit when technologies found, free when no results.

## Output

A list of technologies detected on the given company domain, such as frontend frameworks, CRM tools, analytics platforms, CDN providers, and other software. Returns detected technology names (filtered if a filter list was provided). Returns no results (free call) when no technologies can be identified for the domain.
