## 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 deepline-company-enrichment-api-d2ffede3 -d '<json body>'
```

Example prompt: Can you enrich Acme Corp (acmecorp.com) for me — I need their firmographic data, key decision-makers, and any emails or phone numbers you can find so I can kick off an outbound sequence?

## When to prefer this

Use this endpoint when you need a one-stop enrichment for a specific company that combines firmographics, decision-maker identification, and contact discovery (email + phone) in a single call. Prefer it over point-solution APIs when you need GTM-ready data for outbound sales research and are comfortable with pay-per-request USDC billing.

## Known failure modes

- Company domain not found — returns empty or partial enrichment
- Insufficient USDC balance — payment fails and request is rejected
- Rate limiting if too many requests are fired in rapid succession
- Low-confidence enrichment when company has minimal online presence
- Invalid domain or malformed input returns 4xx error
