# API reference

> Read and write your workspace over REST with an API key.

The Oneprofile REST API lives at `https://api.getoneprofile.ai`. Everything the dashboard does, the API does too: tables, columns, runs, sequences, and the inbox.

## Authenticate

Create a key in the dashboard under **API keys**, then send it on every request in the `X-API-Key` header.

```bash theme={null}
curl https://api.getoneprofile.ai/tables/ \
  -H "X-API-Key: YOUR_API_KEY"
```

<Warning>
  Requests run against your live workspace. A run you start over the API spends credits the same way it does in the dashboard.
</Warning>

## Explore endpoints

Every endpoint page has a playground. Pick an endpoint in the sidebar, paste your key, and send a real request from the browser.
