## 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 mcp-compiler-agentdiet-dev-b2b-company-tech-stack-contact-lead-3405ae18
```

Example prompt: Can you look up everything you can find on hubspot.com — their tech stack, verified contact emails, social links, and pricing info — I want a full company enrichment for our outbound sales team?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-signal company enrichment from a single domain lookup — especially when you need tech stack detection alongside contact leads and company summary in one call. Prefer this over point-solutions when your GTM, sales, or research workflow requires 40+ technology signals, verified emails, and social links together without stitching multiple APIs.

## Known failure modes

- Domain not found or invalid — no enrichment data returned
- Domain exists but has no detectable tech stack signals — partial results
- Rate limiting or payment failure via x402 — 402 response requiring payment
- Domain resolves but company data is sparse or outdated — low-confidence results
