Geocoding — entry 001 of 80
ipstack
ipstack (an apilayer product) resolves an IP address to city-level geolocation data via a REST API that always requires an access_key — there is no key-free tier. It advertises a free, no-credit-card-required plan, though the vendor's own pages disagree on the exact request quota, so treat any specific number with caution; paid tiers sit above that for higher volume. The API returns no CORS headers, so browser calls need a server-side proxy.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
