## 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-3196cb5b -d '<json body>'
```

Example prompt: Can you pull up the full company profile for notion.so — I need their tech stack, any verified contact emails, social links, and pricing tier info for a sales research report.

## When to prefer this

Choose this endpoint when you need a fast, single-call enrichment of a B2B company domain that combines tech stack intelligence, verified contact emails, social links, and pricing signals in one payload — ideal for GTM agents, sales automation, and competitive research workflows where breadth of signal (40+ tech signals) matters more than deep OSINT on any single dimension.

## Known failure modes

- Domain not found or unresolvable — returns empty or null fields
- Private/internal domain with no public signals — minimal data returned
- Rate limiting or payment failure via x402 — HTTP 402 response requiring USDC payment
- Malformed domain input — validation error with 400-level response
- Stale or incomplete tech stack data for newly launched or obscure domains
