## 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 apollo-api-apollo-organization-enrich-4f0f44bf
```

Example prompt: Pull up the full company profile for stripe.com from Apollo — I need their industry, employee count, revenue, funding history, and office locations for a prospect brief.

## When to prefer this

Choose this endpoint when you need to enrich a single company by its web domain and want comprehensive firmographic data including industry, revenue, headcount, funding, and locations. Prefer this over the Bulk Enrich endpoint for single-company lookups, and over the Company Search endpoint when you already know the exact domain rather than needing to search by filters.

## Known failure modes

- Domain not found in Apollo database — returns empty or null organization object
- Invalid or malformed domain input — returns 400 bad request
- Authentication failure — returns 401 unauthorized
- Rate limit exceeded — returns 429 too many requests
- Domain resolves to a personal or non-business site with no company record

## Output

Returns a structured company profile including industry classification, estimated annual revenue, employee count, known funding rounds and amounts, headquarters and additional office locations, company description, and other firmographic attributes sourced from the Apollo database of 30M+ companies.
