## LatLng

- `data-apis/latlng` | qualifies-with-caveat | evidence documented | binding volume-quota | category geocoding, places and map tiles API | tier Free
- needs card no, phone no, ID no, institution no | verified 2026-11-02T00:23:41.926Z (live) | stale on 2026-12-03
- url https://www.latlng.work/docs
- free tier: Free plan, USD 0 a month, no credit card: 3,000 forward geocodes a day, 300 reverse geocodes a day and 100 places searches a day by the terms table; the API docs describe one unified pool of 3,000 total API calls a day shared by geocoding, reverse, places and tile requests | unit: requests | metered on: request-count | read on: 2026-11-02 | source: [1] | note: the terms table and the docs page describe the daily quota differently, and which one applies is unverified; calls without any key are also answered in small numbers (the Python SDK page says 30 geocodes a day, and a keyless call returned an x-ratelimit-limit header of 60); the Pro plan is USD 29 a month for 1,000,000 geocoding requests a month
- per-object cap: no batch endpoint: one address a request, and the batch geocoding page sends 10 to 50 parallel single requests; Free dataset uploads are 3 datasets of at most 50 MB each | source: [2]
- retention: no rule for storing results is stated | source: [1]
- egress: not applicable: a query API metered in requests, not bytes | metered: no | source: [3]
- identity: email | detail: an account at dash.latlng.work, a JavaScript sign-in page whose fields are not in the page text; the vendor's page says to sign up with an email or GitHub and get instant API keys with no credit card; one account and one API key per entity on the free tier; the form fields themselves are unverified: behind a sign-up
- interface: rest
- limits:
  - volume-quota (binding): 3,000 forward geocodes, 300 reverse geocodes and 100 places searches a day on the Free plan (terms table); the docs list one pool of 3,000 total API calls a day [1]
  - request-rate: no per-second limit is published; the API answers HTTP 429 when the quota is exceeded and sends X-RateLimit-Limit and X-RateLimit-Remaining headers [3]
  - per-object-cap: 3 datasets of at most 50 MB each on the Free plan [3]
- binding note: no per-second figure is published, so the daily quota is the ceiling that is stated and met first
- interface detail: HTTPS GET to api.latlng.work/api (forward) and /reverse with the key in an X-Api-Key header or an api_key parameter, GeoJSON answers; places, static map and autosuggest endpoints and vector tiles at tiles.latlng.work use the same account; a call without any key answered HTTP 200 with GeoJSON and an x-ratelimit-limit header of 60
- endpoint: https://api.latlng.work/api
- tooling: any HTTP client; an official Rust crate and a Python SDK
- composes with: 3,000 forward geocodes a day on an email or GitHub account with no card, built on OpenStreetMap data, plus 300 reverse geocodes a day and vector tiles on the same key; public applications must show the OpenStreetMap attribution; bulk work is parallel single requests since no batch endpoint exists
- reliability: exceeding the plan limits may suspend access to the affected service, and extra free accounts opened to get more quota can end every account; the allowance without a key is small
- notes: Free requests: 3,000 forward geocodes a day (the docs describe a shared 3,000-call pool). Rate limit: no per-second figure published. Caching is advised and scraping to build a competing dataset is barred. Bulk path: none; parallel single requests.
- evidence note: the home page, the docs, the terms, the batch geocoding page, the Python SDK page and the key-free sign-up page were quoted on 2026-11-02; a call without a key answered HTTP 200 with GeoJSON. No account was opened, so the free daily quota and the sign-up fields were not exercised.
- extras:
  - free_requests: 3,000 forward geocodes, 300 reverse geocodes and 100 places searches a day (terms); 3,000 total calls a day (docs)
  - rate_limit: unverified: no per-second limit is published; a key-free call returned x-ratelimit-limit 60
  - bulk_path: none: no batch endpoint; parallel single requests, 10 to 50 at a time
