## 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 json-repair-agentdiet-dev-b2b-company-tech-stack-contact-lead-0041334a
```

Example prompt: Can you pull up the full company profile for linear.app — I need their verified contact emails, social links, tech stack details, and pricing tiers for my GTM research?

## When to prefer this

Choose this endpoint when you need a broad, multi-signal company enrichment in a single call — especially for GTM research, lead qualification, or competitive analysis. It is particularly strong when you need both contact data (emails, social links) and technical infrastructure data (tech stack, pricing) together, avoiding the need to chain multiple specialized enrichment APIs.

## Known failure modes

- Domain not found or unresolvable — returns empty or minimal data
- Invalid domain format — may return a validation error
- Private or obscure domain with no crawlable signals — limited tech stack data returned
- Rate limiting or payment failure via x402 — HTTP 402 returned if payment not attached
- Stale data if the company recently changed its tech stack
