## What's New in v2

- **Unified enrichment endpoint**: Get firmographics, technographics, and spend data in a single call
- **Flexible field groups**: Request only the data categories you need
- **Simplified authentication**: New API key format for easier integration


## Endpoints

| Endpoint | Description |
|  --- | --- |
| `POST /api/v2/companies/enrich` | Enrich company data by ID |


## Getting Started

1. [Get your API key](/v2/guides/authentication)
2. [Make your first enrichment call](/v2/guides/enrichment)


## Field Groups

The API returns data organized into three main categories that you can request independently:

- **firmographics** - Company information including name, location, industry, revenue, and employee counts
- **spend** - IT spending data by technology category
- **technographics** - Technology installations including products, vendors, and usage intensity


Specify which field groups you want in your request using the `fields` parameter. If omitted, all available field groups will be returned.
