Model API costs

You can now retrieve your Model API spend through the Management API. The new GET /v1/billing/model_apis endpoint returns exact subtotals for each calendar day, rated from your usage.

curl --get "https://api.baseten.co/v1/billing/model_apis" \
     -H "Authorization: Bearer $BASETEN_API_KEY" \
     -d "start_date=2026-09-04" \
     -d "end_date=2026-09-11"
