Both plans

  • MCP (OAuth or API key), REST, and the /try playground on one meter
  • Up to 2 active API keys
  • Only coverage: scored is billed. Validation errors and cannot_score are free
  • explain_grade and health never touch the meter

Over the cap

REST returns HTTP 402 with the Builder upgrade in the JSON body. MCP returns a score_quota_exceeded tool error that says what Builder costs. Your agent gets an error, never a made-up grade. The meter resets on the first of the month, UTC.
