Pricing

Pay for the signals you use.

Separate from Kavout Pro
Pro is the app; Signal DB is the data behind it. Same login, separate billing — no Pro plan required, and Pro does not include the API.
Personal-use license
Redistribution or use in a product needs a commercial license — contact sales. K Score for US and China are sold through sales.
Limits
10,000 rows per request, 120 requests per minute. Full history via CSV download — see limits.

Start with one signal. Scale to all nine.

From $39/mo per signal · every signal for $199/mo · cancel any time.
