# Settings & API keys

> Project credentials and ingest configuration.

The **Settings** page manages your project's identity and credentials.

## Project

Shows the **Project ID** — the stable identifier every trace is scoped to.

## API keys

API keys authenticate your agent's traces to this project.

* **Create key** — generate a new `sk_…` secret. It's revealed **once**, with a
  copy button and an "I've copied the key" confirmation that then hides it. Only
  a hash is stored — the secret is never shown again and never logged.
* The keys table lists each key's name, public key, and creation date.

<Warning>
  If a key leaks, generate a new one and stop using the old one. Secrets are
  never recoverable after creation.
</Warning>

## Sending traces

Settings shows the ingest snippet for your project:

```bash theme={null}
curl -X POST https://ingest.runagain.ai/v1/traces \
  -H "x-runagain-key: $RUNAGAIN_API_KEY" \
  -H "Content-Type: application/json" \
  --data @trace.json
```
