# LeadX API

> The LeadX API makes it simple to look up companies, pull contacts, and validate information.

Every request follows a consistent URL structure:

```bash theme={null}
https://api.leadx.com/v1/{endpoint}
```

Endpoints represent resources you can work with, such as `/companies` to look up enriched company metadata. Detailed descriptions and parameters for each endpoint can be found in the [API Reference](/endpoints/all-attributes). Get started using the resources below.
