API availability and key identification.

## Endpoints

Both endpoints use `https://api.neondeerdata.com/v1`.

| Endpoint                                                                  | Key required | Response                                                |
| ------------------------------------------------------------------------- | ------------ | ------------------------------------------------------- |
| [Who am I](https://neondeerdata.com/docs/api/meta/self/) · `GET /v1/self` | Yes          | Your key, its organization, scopes, and access summary. |
| [Ping](https://neondeerdata.com/docs/api/meta/ping/) · `GET /v1/ping`     | No           | Whether the API responds.                               |

## Check a connection

Use Ping to check that your application can reach the API. Then send Who am I with your application's key to check its identity and organization. A [lookup-table request](https://neondeerdata.com/docs/api/lookup-tables/) checks access to data.

The public [OpenAPI document](https://api.neondeerdata.com/v1/openapi.json) contains the API schemas and needs no key.
