Pay for the searches you use
Every plan starts with 2,500 free searches a month. After that it’s $0.50 per 1,000, and $0.35 above 5 million. You choose a monthly limit, and it’s a hard stop.

No key at all
The API and MCP server answer without a key: 60 searches a minute and 50 a day from each address, free. You can show those answers, but not keep them.
What’s always free
Checking your use never counts as a search. Neither does a search that failed or was refused.
Questions
What counts as one search?
One call to
/v1, or one hottub_search call over MCP, that returned an answer.What happens when I reach my monthly limit?
Searches are refused with
spend_cap_reached until the 1st, or until you raise the limit on your keys page. Nothing past the limit is ever billed.Do I need a card for the free key?
No. A Hottub account is enough. You add a card through Stripe only when you choose a paid plan.
Does paying change the results?
No. Payment never changes the order of results. The service that ranks results is built without this price card. Paid plans can leave out sponsored rows and don’t have to show the credit line.
Can I keep what I find?
Yes, on every plan with a key: store results and show them later, each with a link to its page. A result marked
"storable": false came from another provider; show it, but don’t keep it. The full rulesMore than $25,000 a month?
Write to support@hottub.tech and we’ll set a limit that fits.
