Need a custom volume?
Above 200,000 credits a month, the price is set on your actual usage. Same engine, same credits, on every surface.
What will your prospecting cost?
Nobody knows off the top of their head, because each action has its own price. Set your volume, pick what you look up, and you get your cost per prospect.
How many records a month?
What are you looking up?
Ceiling, not an average: this charges every datapoint on every row. Email Finder and Phone Finder only bill for results actually found, so your real cost lands lower.
What each action costs
The price depends on the action, not on the plan. The plan only sets what you pay per credit, and what is unlocked.
How the pricing works
Four rules, and they do not change with the plan.
- 01
You buy credits, not seats
The whole team works on the same balance. Adding a colleague costs nothing; only what you look up is charged.
- 02
Each action has its own price
An enrichment is not a phone number. The table below gives the credit cost of every action, so a month is predictable before it starts.
- 03
Nothing found, nothing charged
A lookup that returns no match costs no credit. That is also why the tool says when it found nothing instead of guessing.
- 04
The same balance on four surfaces
The web app, Google Sheets, an AI assistant through MCP, or the REST API: same engine, same credits, one bill.
Compare the real cost
What a lookup actually costs, with the sources, on 84 tools. Read the breakdown before you take a price at face value.
Is there really a free plan?
+
Yes. 100 credits every month, no card asked. It is enough to run a real lookup on your own list and measure the hit rate before paying anything.
What is a credit worth?
+
It depends on the action, not on the plan: finding an email costs 5 credits, a phone number 200, enriching a profile 1. The plan only changes the price you pay per credit, from €0.0016 on the largest one.
Do unused credits expire?
+
No, they roll over. A quiet month is not a month lost, which matters when prospecting comes in waves.
Can I change or stop my plan?
+
Yes, whenever you want: from Plan & billing in the web app, or from the add-on settings in Google Sheets. There is no commitment and no notice period.
Which plan unlocks the API and the MCP?
+
API keys unlock from the Plus plan. The MCP server uses the same key, so it follows the same rule: one key, both surfaces, on the same credit balance.
What if I need more than the largest plan?
+
Write to us. Above the top tier the price per credit is set case by case, and the usage calculator on this page tells you when you are getting there.
