## 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-5dd22a07
```

Example prompt: Can you pull up the full company profile for notion.so — I want to see their tech stack, pricing tiers, verified contact emails, and social links so I can prep for a GTM outreach?

## When to prefer this

Choose this endpoint when you need multi-signal B2B company enrichment in a single call — combining tech stack detection, verified contact emails, social links, and pricing tiers — rather than calling separate tools for each data type. Ideal for GTM agents, sales automation pipelines, and CRM enrichment workflows where a company domain is the only known input.

## Known failure modes

- Domain not found or unresolvable — returns empty or error response
- Domain with no detectable tech stack or pricing page — partial data returned
- Invalid domain format — schema validation error on required 'domain' parameter
- Private or newly registered domain with insufficient public signals — limited results
- Rate limit or payment failure via x402 — HTTP 402 or 429 response
