## 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 serp-extract-agentdiet-dev-b2b-company-tech-stack-contact-lead-cad39261 -d '<json body>'
```

Example prompt: Can you pull up the full company profile for stripe.com — I need their verified contact emails, tech stack breakdown, social links, and pricing tier info for my GTM research.

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-signal B2B company profile from a single domain input — especially when you need tech stack intelligence alongside contact and firmographic data in one call. Prefer this over point-solution enrichment APIs when your GTM or research workflow requires emails, social links, pricing context, and tech signals together without chaining multiple services.

## Known failure modes

- Domain not found or invalid: returns empty or null fields
- Domain is too new or obscure: limited tech stack signals available
- Rate limiting or payment failure via x402: 402 Payment Required response
- Unresolvable domain format: validation error on input
- Partial enrichment: some fields populated, others null if data unavailable
