## 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-3b11281f
```

Example prompt: Pull the full tech stack, verified contact emails, pricing tier, and company summary for figma.com — I need this for a GTM research report.

## When to prefer this

Choose this endpoint when you need comprehensive B2B company intelligence from a single domain lookup, including tech stack, contacts, and pricing — especially for GTM automation, sales prospecting, or competitive research workflows where breadth of signal (40+ tech indicators) matters more than deep single-category data.

## Known failure modes

- Domain not found or unresolvable — returns empty or error response
- Private or newly registered domain with no crawlable signals — sparse results
- Rate limiting or payment failure via x402 — HTTP 402 response
- Malformed domain input — validation error
- Company has minimal web presence — limited tech stack or contact data returned
