FAQ
The questions people ask on a Friday, before they paste the list. The long version lives on the decision makers page.
volume
I have several hundred domains — what does that cost?+
A delivered row is email 2, phone 4, both 8. No-finds are free. Twenty domains per synchronous call; two or more in the workbench become a job.
Can I send more than twenty items per request?+
Twenty domains per synchronous call. Split a longer list and give each call its own Idempotency-Key. In the workbench, two to twenty domains become a job.
What if credits run out mid-list?+
The call that cannot be covered answers 402 and does not run. Earlier calls are already committed and unaffected.
email quality
What does SMTP verified mean?+
The mail server accepted the mailbox during verification. It says the address resolves, not that the person will reply.
Why is an email not sendable?+
Sendable needs verification result ok, quality good, and the identity gate. Miss any one and the flag stays false.
Do no-finds cost credits?+
No. Only delivered rows are committed.
cost and billing
What does a credit cost?+
It depends on the pack: €49 for 500, €99 for 1 500, €199 for 4 000, €399 for 8 500 on the public list. Credits do not expire. Packs has larger sizes. Auto top-up charges the same pack on the saved card when you cross your threshold — it is not a monthly plan.
Where are my invoices?+
In Packs, after you have bought a pack. Open Manage billing for receipts and card. Packs are one-time. Auto top-up charges the same pack on the saved card at your threshold, including API calls.
Does every tool cost one credit per result?+
No. A delivered decision-maker row is email 2, phone 4, both 8. A no-find is free.
What is HTTP 402?+
The answer you get when your balance cannot cover a request. It carries the required and available amounts, and nothing runs.
access
How do I get my API key?+
Sign up, then create it under API key. The secret is shown once. Copy it for curl and scripts. Claude, ChatGPT and Cursor connect at /mcp with your login — they do not need this key. Lookups in the portal use the copy kept on this device.
I created a key and lost it+
We cannot show the secret again. Rotate it under API key: the old key dies immediately and a new one is shown once.
Can I rotate the key myself?+
Yes. API key → Rotate key. There is no grace period. Anything still using the old value gets 401.
Is there a login?+
Yes. Email sign-up. Claude and ChatGPT reuse that login over MCP. The API key is for REST and scripts, not the website login.
Every answer here stops at the same line: verification and reachability are technical signals. Whether you may contact someone is your call, and the legal page says so in more words.
Start with €49. Spend it whenever.
500 credits, 250 delivered rows, no renewal date.
