## 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-2247d794
```

Example prompt: Can you pull up the full company profile for notion.so — I need their verified contact emails, tech stack, social links, and pricing tiers for my outbound research?

## When to prefer this

Choose this endpoint when you need a broad, multi-signal enrichment of a single company domain in one call — covering contacts, tech stack, social presence, and pricing — rather than hitting separate point solutions for each signal. Ideal for GTM agents doing outbound research, ICP scoring pipelines, or competitive intelligence workflows where per-domain cost efficiency matters.

## Known failure modes

- Domain not found or does not resolve to a known company — sparse or empty result returned
- Invalid or malformed domain input — validation error
- Private or newly registered domain with insufficient crawl data — partial result with missing fields
- Rate limiting or payment authorization failure via x402 — HTTP 402 response
- Transient enrichment data source unavailability — timeout or degraded response
