Credits and limits
See what uses a credit, when credits reset, and how short bursts work.
SignupScore gives your account one monthly credit balance. API requests, dashboard checks, and bulk jobs use that same balance.
How credits work
One completed check uses one credit. The Free plan includes 250 credits per month.
For example, 300 API checks and a bulk job with 200 unique inputs use all 500 Free credits. Creating another API key does not add more credits.
Invalid input does not use a credit. If SignupScore cannot complete a check, the credit is not kept.
Monthly reset
Monthly credits reset at the start of each month in UTC. The Billing page shows your next reset date. If you run out, the API returns the same date in X-Quota-Reset.
Unused monthly credits do not roll over.
Throughput limits
Pricing shows an average requests-per-second rate so plans are easy to compare. Your requests do not need to arrive at perfectly even one-second intervals.
For example, Free allows up to 10 requests within 10 seconds. You can send eight requests together and two more a moment later. If you send more than the short-burst limit, the API returns 429 and tells you how long to wait in Retry-After.
