## 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-867128ea
```

Example prompt: Look up stripe.com and give me their verified contact emails, tech stack, and a company summary — I need it for a sales pitch.

## When to prefer this

Choose this endpoint when you need a single-call, multi-signal B2B company enrichment covering tech stack, contacts, and company metadata. It is especially valuable for GTM agents, sales pipelines, and research workflows that need verified emails plus technology fingerprinting in one response, rather than piecing together data from multiple specialized APIs.

## Known failure modes

- Domain not found or invalid — returns empty or error response
- Unverifiable or private domain with no public signals — sparse results
- Rate limiting or payment failure via x402 — HTTP 402 response
- Malformed domain input — validation error on the required 'domain' field
- Company with very limited web presence — incomplete tech stack or contact data
