## 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-aa2f526d
```

Example prompt: Can you pull up everything you can find on hubspot.com — verified contact emails, their tech stack, pricing tiers, social links, and a quick company summary? I'm building a prospect list.

## When to prefer this

Choose this endpoint when you need a broad B2B enrichment profile for a single company domain, especially when you want tech stack signals alongside contact and firmographic data in one call. Prefer this over dedicated firmographic APIs when tech stack intelligence is required for GTM targeting or when you need a fast, cost-effective single-domain lookup at $0.02 per call rather than bulk enrichment platforms.

## Known failure modes

- Unknown or unregistered domain returns empty or minimal results
- Private or newly registered domains may yield few tech signals
- Rate limits or payment failures result in HTTP 402 responses
- Malformed domain input (missing TLD, spaces) may return a validation error
- Some fields (e.g. emails, pricing) may be absent if not publicly discoverable
