Pricing
Matching on the web is free. Agents and developers get a free API tier and can buy a key for more.
| Plan | Price | What you get |
|---|---|---|
| Web matches | Free | Up to 20 matches a day from one address, with the form on the home page |
| API and MCP, free tier | Free, no key | 5 match calls a day per address; topic lookups and results within fair use |
| API key | $29/month | 500 match calls a day per key, by JSON API or MCP; cancel any time |
Buy an API key
Polar (polar.sh) is the merchant of record: it takes the payment, handles tax and emails you the key. Send the key as an Authorization header (Bearer followed by the key) to the API or the MCP endpoint. Buying or using a key means you accept the Terms, including the API section (fair use, no resale of the raw data as a competing service, the same limit of liability).
Automated matching only, not legal advice or proposal advice.
