What happens after a visitor enters an address?

Use address lookup to get coordinates, the numbers that place a pin on a map. LocationIQ also offers suggestions while a person types. Show which address the person selected so they can correct a plausible-looking result on the wrong street.

Map tiles draw the background. A route is another operation. If people only need to find a fixed venue, check whether a saved, verified pin and written entrance instructions are enough.

What does the Free plan count?

LocationIQ lists 5,000 requests per day on Free, with shorter rate limits too. A suggestion box can make more than one request for a single address. The pricing FAQ describes limited commercial use and asks for its prescribed link.

Check which features are available under the selected plan and what the app should show when it reaches a limit.

Which location information can you keep?

Keep the address your venue owner gave you separately. LocationIQ’s terms distinguish temporary caching of a request and its response from storing response data. They list up to 48 hours for that cache on Free and disallow server-side caching of map tiles.

Check the terms for the particular data you plan to store or reuse, especially when you switch providers.

How would you plan a lookup with two similar results?

Write two made-up places with the same street name. Use no key, provider request or actual address.
