## 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 agentdiet-dev-b2b-company-tech-stack-contact-lead-enrichment-73559d49
```

Example prompt: Can you pull up all the tech stack details, verified contact emails, and social links for notion.so — I need a full company enrichment profile for my GTM research.

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call B2B company enrichment that combines contact discovery, tech stack detection, and company profiling from just a domain name. Ideal for GTM agents, lead scoring pipelines, and competitive research workflows where breadth of signals (40+ tech signals + emails + social + pricing) matters more than depth in any single category.

## Known failure modes

- Domain not found or unresolvable — returns empty or null fields
- Private/parked domain with no enrichable signals — minimal data returned
- Stale cache data for rarely-visited domains — tech stack may be outdated
- Invalid domain format — request validation error
- Payment failure via x402 — HTTP 402 returned if USDC balance insufficient
