## 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-ddb47ca5 -d '<json body>'
```

Example prompt: Can you enrich stripe.com and give me their verified contact emails, social profiles, tech stack tools they're running, and a company summary so I can prep for an outreach campaign?

## When to prefer this

Choose this endpoint when you need comprehensive B2B firmographic enrichment in a single call — combining email discovery, social links, tech stack detection (40+ signals), pricing intelligence, and company summary together. Prefer it over point-solution tools when your agent needs GTM-ready intelligence from just a domain name, especially for sales prospecting, competitive research, or lead qualification workflows.

## Known failure modes

- Unknown or mistyped domain returns empty or minimal data
- Private/stealth-mode companies may have limited public signals
- Tech stack detection may miss tools behind firewalls or server-side only
- Rate limiting or payment failure results in HTTP 402 or 429 response
- Very new domains may return sparse firmographic data
