## 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 sitecheck-contact-enrichment-api-84ac2e11
```

Example prompt: Can you find the contact emails, LinkedIn page, and tech stack for plausible.io?

## When to prefer this

Use this endpoint when you need fast, no-signup contact and company enrichment for a known domain — especially useful in lead generation, sales prospecting, or competitive research workflows where you need emails, social links, and tech stack in a single call. Prefer it over manual scraping or heavier data enrichment APIs when cost-efficiency ($0.01/call) and zero-credential setup matter.

## Known failure modes

- Domain not found or unreachable — may return empty or partial results
- No publicly discoverable emails — emails array will be empty
- No social profiles found — socials object will be empty or missing keys
- Invalid URL input — may return an error or empty response
- Rate limiting or payment failure via x402 — call does not complete

## How this service works

Pay-per-call tools for AI agents: image generation, speech-to-text, text-to-speech, embeddings, LLM chat, website audits and contact enrichment. Plus prediction-market search, briefs, quotes and unsigned buy transactions, powered by Panta. Payment: x402, USDC on Base, Solana or Arc. No signup, no API key.

## Output

Returns a JSON object with the company name, domain, an array of email addresses (with a flag indicating if the email matches the domain), detected technology stack (e.g. Cloudflare), and social media profile URLs (e.g. LinkedIn).
