We check SLF's listed URL (https://github.com/slftool/slftool.github.io/blob/master/API.md) once a day. History started when SLF was first checked, so new entries show fewer than 30 days.

SLF API not working for you?

  1. A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header.
  2. If it works from one network but not another, check firewalls, VPNs and regional blocks.
  3. Check the provider's documentation, status page or social accounts for planned maintenance or a changed endpoint.

SLF API status FAQ

Is SLF API down right now?

SLF answered our last daily check (Oct 24, 2026, 12:25 UTC) in 577 ms with HTTP 200. This page also runs a live check from our server when you open it, so you can see whether SLF is responding at this moment.

How do you check whether SLF API is up?

Once a day our checker requests SLF's listed URL (https://github.com/slftool/slftool.github.io/blob/master/API.md) and records whether it answers within 15 seconds. Answers like 401 (needs a key), 403 (blocks bots) or 429 (rate-limited) count as up, because the server responded. The listed URL is often the documentation page, so an API endpoint can occasionally fail while its docs stay up.

What can I use if SLF API is down?

Free Geocoding APIs that were up at their last check include ipwhois, administrative-divisons-db, HackMyIP. See the full list of SLF alternatives for a comparison.

Why does SLF API work for others but not for me?

A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header. If it works from one network but not another, check firewalls, VPNs and regional blocks. Check the provider's documentation, status page or social accounts for planned maintenance or a changed endpoint.
