## 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 company-batch-enrichment-api-72beb002
```

Example prompt: Can you pull up company profiles and tech stacks for stripe.com, notion.so, and linear.app — I want to know what technologies they each use, their social links, and what email provider they're on?

## When to prefer this

Choose this endpoint when you need to enrich multiple company domains (up to 10) in a single API call and want both profile data (name, description, socials, email provider) and technology detection. It is ideal for B2B lead enrichment, competitor research, and sales intelligence workflows where you need structured company metadata without accessing personal data. Prefer this over single-domain lookups when processing batches, and over full web scrapers when you only need lightweight company profiles and tech signals.

## Known failure modes

- More than 10 domains submitted — API rejects or truncates the list
- Invalid or non-existent domain returns empty or null company record
- Domain resolves but has no detectable tech stack, returning empty technologies array
- Rate limiting or payment failure (x402 payment required) blocks the request
- Malformed comma-separated domains string causes query parse error

## How this service works

Invoice-to-JSON, on-chain tools (transaction explainer + payment check, wallet profile, contract ABI, ERC-20 token risk), company contacts and web-to-RAG for AI agents. Pay per call with x402 (USDC on Base). No signup, no API key.

## Output

Returns a JSON object with an array of company records, each containing the domain, company name, description, detected technologies (e.g. React, Cloudflare), social media links, key pages, and email provider. Also includes a top-level count of successfully enriched companies.
