Credits

UserCheck uses a credit-based billing model. Each API request consumes one or more credits depending on the endpoint and features used. Your plan includes a fixed number of credits per billing period.

Credit costs

Request type	Credits
Domain lookup (GET /domain/{domain})	1
Email lookup (GET /email/{email})	1
Gates decision (POST /v0/gates/{gate_id}/decisions)	1

Optional features

Some request parameters consume additional credits on top of the base cost:

Feature	Extra credits
IP lookup (include ip in Gates request body)	+2

For example, a Gates decision costs 1 credit by default. Adding the ip parameter for IP intelligence brings the total to 3 credits.

Plans

Each plan includes a set number of credits per month:

Plan	Credits per month	Price
Free	1,000	$0
Pro 200K	200,000	$50/mo
Pro 500K	500,000	$100/mo
Pro 1.5M	1,500,000	$250/mo
Pro 3.5M	3,500,000	$500/mo

Credits reset at the start of each billing cycle. Unused credits do not roll over.

Credits vs. rate limits

Credits and rate limits are separate concepts:

• Credits are your monthly quota — how many total credits you can use in a billing period.
• Rate limits control throughput — how many requests per second your plan allows.

A single API request always counts as one request toward your rate limit, regardless of how many credits it costs.

Checking your usage

Use the Status endpoint to check your current credit usage:

curl -X GET "https://api.usercheck.com/status" \
  -H "Authorization: Bearer YOUR_API_KEY"

The response includes your plan's credit limit, current usage, and remaining credits for the billing period.
