## 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 alpha-stream-agentdiet-dev-b2b-company-tech-stack-contact-lead-ea07721a
```

Example prompt: Can you pull up full firmographic intel on hubspot.com — I need their verified contact emails, tech stack breakdown, pricing tiers, and social profiles for our GTM research?

## When to prefer this

Choose this endpoint when you need a single-call, broad firmographic enrichment covering tech stack, contacts, social profiles, and pricing tiers from just a domain name. Prefer it over point-solution APIs (e.g. email-only or tech-detection-only tools) when you need multiple GTM signals in one shot at a low per-call cost ($0.01).

## Known failure modes

- Domain not found or unresolvable: empty or null result fields
- Invalid domain format: likely a 400 bad request or validation error
- No public data available for obscure or private domains: sparse results
- Rate limit exceeded: HTTP 429 or payment required response
- Payment not processed: HTTP 402 if x402 payment flow fails
