## 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 defi-yield-agentdiet-dev-b2b-company-tech-stack-contact-lead-enrichment-89ae6053
```

Example prompt: Can you pull up everything you can find on stripe.com — their verified contact emails, social links, tech stack, and pricing tiers? I need it for a sales prospecting run.

## When to prefer this

Choose this endpoint when you need a one-shot, breadth-first company enrichment covering tech stack, contacts, social presence, and pricing from a single domain lookup — especially for GTM automation, sales prospecting, or startup research workflows where multiple data points are needed simultaneously rather than calling separate specialized APIs.

## Known failure modes

- Domain not found or unresolvable — returns empty or partial results
- Invalid or malformed domain string — may return an error or null data
- Private or very small company with no detectable public signals — sparse output
- Payment failure via x402 — endpoint returns 402 before delivering results
- Rate limiting or quota exceeded — returns error response
