OAuth2 client_credentials

In the developer portal, create an App → Issue OAuth client.
Exchange:

curl -X POST https://api.partgenie.ai/developer/oauth/token \
  -H 'Content-Type: application/json' \
  -d '{
    "grant_type": "client_credentials",
    "client_id": "pg_cid_…",
    "client_secret": "…"
  }'

Call API with Authorization: Bearer pg_at_….

API keys (pg_test_ / pg_live_) remain supported on the same App.
