Eval packs: versioned question sets with verified answers and citations for testing your agent, in `coding`, `drugs` and `providers`. Every pack with every version (newest first), its question count and the dataset versions its answers were verified against. Team plan (403 `plan-upgrade-required` on other plans). Not metered.

Requires an API key: `Authorization: Bearer hdev_live_...`. See [Authentication](/authentication).

```sh
curl "https://api.healthcare.dev/v1/eval-packs" \
  -H "Authorization: Bearer $HDEV_API_KEY"

  headers: { Authorization: `Bearer ${process.env.HDEV_API_KEY}` },

```
