Scoring endpoints consume credits; reading your configuration and checking status are free. Your plan includes a monthly credit allowance, and each scored response reports its cost in a credits_consumed field.
Credits reset monthly and do not carry forward. Manage your plan and watch usage on the dashboard.

​
What’s free

These endpoints never consume credits:
EndpointPurpose
GET /railscore/v1/configSee your application’s policy and configuration
GET /railscore/v1/dimensionsThe RAIL dimensions and your weights/thresholds
GET /railscore/v1/capabilitiesFeatures and limits for your plan
POST /verifyValidate a key and view your identity
GET /healthService status
Cached scoring results also return at no cost.

​
What’s metered

Scoring work is metered by how much analysis it does. Approximate costs:
OperationRelative cost
Evaluation, basic modeLowest
Evaluation, deep modeHigher (more detailed analysis)
Safe regenerationPer evaluation + per rewrite, up to 5 iterations
Compliance checkPer framework evaluated
Agent checksLow, per call
Evaluating a subset of dimensions costs proportionally less than scoring all eight. The exact credits_consumed is always returned on the response, and live per-plan pricing is shown on the dashboard.
