Rate Limits and Quotas

ZeroTrain API usage is governed by subscription-tier limits. Limits are enforced per APIKey.

Enforced Limits

• Requests Per Minute (RPM) – Maximum evaluation calls allowed per minute.
• Concurrent Executions – Maximum simultaneous evaluations allowed.
• Payload Size – Maximum request body size.
• Rows Per Evaluation – Maximum ModelSource rows processed per request.
• Columns Per Evaluation – Maximum ModelSource columns processed per request.

Rate Limit Exceeded

When a rate or quota limit is exceeded, the API will return:

• 429 Too Many Requests

Clients should implement retry logic with exponential backoff when receiving a 429 response.

Tier-Based Enforcement

Limits vary by subscription tier. Higher tiers provide increased throughput, concurrency, and evaluation capacity.

Contact your account administrator for limit adjustments.
