## 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 preflight-agentdiet-dev-b2b-company-tech-stack-contact-lead-enrichment-151f764c
```

Example prompt: Can you look up everything you can find on linear.app — their tech stack, verified contact emails, social links, pricing tiers, and a company summary? I need it for a GTM research brief.

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-signal B2B company profile from a single domain lookup — combining tech stack detection, verified contacts, social links, and pricing in one call. Prefer it over generic web scrapers or single-signal enrichment APIs when building GTM pipelines, lead qualification workflows, or competitive research agents that need structured, ready-to-use company intelligence without assembling multiple data sources.

## Known failure modes

- Domain not found or unresolvable — returns empty or null fields
- Private or parked domain with no detectable tech stack — limited signal output
- Rate limiting or payment failure via x402 — HTTP 402 returned
- Malformed domain input — validation error with guidance to correct format
- Recently launched domain with insufficient web presence — sparse results
