## 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 serp-extract-agentdiet-dev-b2b-company-tech-stack-contact-lead-6ec36805
```

Example prompt: Can you pull up full firmographic details for stripe.com — I need their verified contact emails, social profiles, tech stack signals, and any pricing tier info you can find?

## When to prefer this

Choose this endpoint when you need comprehensive firmographic enrichment for a single company domain in one call — including tech stack depth (40+ signals), pricing tier context, and verified contact data — rather than using separate point solutions for email lookup, tech detection, and company profiling.

## Known failure modes

- Unknown or unresolvable domain returns empty or error response
- Private or very new domains may yield sparse tech stack data
- Rate limits or payment failures (402) may block requests
- Unverified emails may not be returned if none are publicly detectable
- Incorrect domain format may result in validation error

## Output
