Pricing
10 credits for an answer. Nothing for a dead end.
No subscription, no seats, no minimum. Lookups draw whole Ounie credits from the single wallet you already share across every Ounie app. One credit is one cent.
One lookup
Charged when we return an address — whatever its verification status. The pattern work was done and the answer carries an honest label, so it bills the same whether it came back verified or accepts-all.
- Up to four address shapes tested per lookup
- Verification status and confidence on every answer
- Catch-all domains reported as accepts-all, never as a hit
- Alternatives returned when the provider supplies them
- REST, MCP and x402 rails included
Always free
- A lookup that finds no address
- A lookup we refuse before running it
- A lookup we could not run because the engine was down
- Reading, listing and exporting past lookups
Refunds are automatic and immediate. There is no ticket to file and no credit that quietly stays spent. If the lookup engine is unavailable we say so up front rather than reserving your credits and handing them back.
Agents · x402
Keyless agents pay in USDC on Base — no Ounie account needed. The premium over the credit price covers on-chain settlement.
Nothing settles unless an address is found. An on-chain payment has no refund path, so the check happens before the money moves rather than after.

What does “verified” actually mean here?
That the receiving mail server accepted that specific mailbox, and that we confirmed it distinguishes real mailboxes from invented ones. It is the only status that means the address was confirmed. If we could not establish that, you get accepts-all or unverified instead — never a green tick we did not earn.
What is a catch-all domain, and why does it matter so much?
Some domains accept mail addressed to anything at all, real mailbox or not. A probe against such a domain returns “OK” for an address that cannot exist, so acceptance proves nothing. We report those as accepts-all. It is the single most common way email tools mislead people: they take that “OK” at face value and show it as a hit.
Do I pay when nothing is found?
No. A lookup that returns no address settles at zero credits automatically. You pay for an answer, not for the attempt.
Do I pay for an accepts-all or unverified result?
Yes. The pattern work was done and you get a usable answer plus an honest label on it. We price the work, not the confidence — and we would rather bill you for a labelled guess than quietly upgrade it to a confirmation.
Can I look up a Gmail or Outlook address?
No, and we refuse those before charging you. A personal address at a consumer mailbox provider is one of millions of plausible strings, not a company pattern. Guessing at it is not a product.
Can I run a whole list, or enumerate everyone at a domain?
No. Email Finder answers one named person at one named company at a time. There is no bulk enumerator here — sweeping a domain for whoever happens to exist is a different and considerably worse thing to build.
Should I send cold volume to an unverified address?
No. Bounces damage your sending domain's reputation, and that damage outlasts whatever the campaign was worth. Treat unverified as a lead to confirm another way, not a green light.
How do agents use this without an Ounie account?
Through the x402 endpoint: the agent gets a 402 with payment terms, signs, and retries. Nothing settles on chain unless an address is actually found — the check happens before the money moves, because an on-chain settlement has no refund path.
