## 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 hosaka-company-contacts-tech-stack-lookup-30cacca9 -d '<json body>'
```

Example prompt: Can you pull up all the contact points and third-party vendors for figma.com — I want every email, phone number, social account they list publicly, plus proof of which vendors they rely on?

## When to prefer this

Choose this endpoint when you need to reach a company (not a specific named individual) and want all publicly listed contact methods scraped directly from their own site, or when you need a verified vendor/technology stack profile with evidence. Prefer this over people-search APIs when the target is an organization rather than a person, and over generic tech-stack tools when you need proof records rather than probabilistic guesses.

## Known failure modes

- Domain not found or not a real company — returns empty or error
- Company website blocks scraping — partial or missing contact data
- No third-party vendors detectable — empty vendor list
- Invalid domain format in input — validation error
- Rate limiting or network timeout on target domain — partial results

## How this service works

Company data for AI agents, paid per call in USDC. Reads a company's own DNS to find every third-party vendor it can be proven to use, and returns the record proving each one.

## Output

A structured dossier containing: all contact points (email addresses, phone numbers, social media accounts) scraped from the company's own website, plus a list of every third-party vendor the company is provably using, each accompanied by the supporting record (DNS entry, script tag, etc.) that proves the relationship.
