## 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-3ed4a3f1 -d '<json body>'
```

Example prompt: Can you look up linear.app and give me their verified contact emails, social links, and what tech stack they're running — I need a full GTM lead profile for our outreach campaign?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-signal B2B company enrichment in a single call — covering tech stack, contacts, social links, and pricing — rather than querying separate tools for each signal type. Ideal for GTM agents building outreach lists, competitive intelligence workflows, or research pipelines that need structured company data from just a domain name.

## Known failure modes

- Unknown or unresolvable domain returns empty or minimal results
- Newly registered domains may have insufficient public signals for enrichment
- Rate limiting or payment failure returns HTTP 402 with payment required details
- Malformed domain input returns a validation error
- Some fields may be null if the company has minimal public web presence
