Third-party services
who provides what, and who bills you.
Leadlantern itself sends no data to the author and charges nothing per use. The services below are optional, are run by other companies or communities under their own terms, and bill you directly when they bill at all. No key ships with this code; you create every account yourself.
01Overview
| Service | Used for | Account and key | Who bills you |
|---|---|---|---|
| OpenStreetMap (Nominatim, Overpass) | Finding businesses | None | Nobody. The public servers are shared by everyone and promise no service (below). |
| Google Places API (New) | Finding businesses (optional) | Your Google Cloud project with billing, an API key | Google, to your Google Cloud billing account, per request under Google's price list. |
| Google PageSpeed Insights API | Speed score in the website check (optional) | An API key in your Google Cloud project | Google sets the quota and terms of your key; check them in Google Cloud. |
| AI provider (OpenAI-compatible or Anthropic) | Drafts (optional) | Your account at the provider, an API key | Your provider, for the tokens each draft uses. |
| Resend | Sending e-mail (optional) | Your Resend account, a verified domain, an API key | Resend, for your plan. |
02OpenStreetMap: shared public servers
- The data is © OpenStreetMap contributors under the Open Database Licence (ODbL). Leadlantern shows that credit wherever results are listed.
- The public Nominatim server allows one request per second at most and asks every application to identify itself; Leadlantern sends your contact e-mail in its User-Agent (Place data).
- The public Overpass server is shared by everyone and has no service promise. It can be slow or answer "busy"; Leadlantern then says so and does not retry in a loop.
- For regular or heavy use, run your own Overpass and Nominatim and enter their addresses in Place data.
03Google Places: what a search costs you
- A search makes one to three Text Search requests (20 results each, 60 at most).
- Leadlantern asks for contact and rating fields (phone, website, rating, review count), which places each request in the price tier Google calls Text Search Enterprise. Check the current prices on Google's Places API documentation before regular use.
- Test connection makes one request asking for the place id only.
- Google's details are kept 30 days (Google's 30-day rule). The credit "Powered by Google" is shown with the results.
- Set a budget alert and quotas in Google Cloud so a mistake cannot run up a bill.
04AI provider
Each draft is one request with up to 1,500 output tokens. Test connection is one short request. Only facts about the business and its public website are sent; no e-mail address and no score.
05Resend
Each sent e-mail is one request to Resend. Test connection asks Resend for your domains. Resend sends only from domains you verified with it.
06Not affiliated
