Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Maintenance & community Nominatim +57

LocationIQ 3

We found no changelog, release notes or blog on 4 November (docs.locationiq.com/changelog, locationiq.com/changelog and locationiq.com/blog all return 404, and llms.txt lists none), so there's no dated API change to count. The terms were updated 31 March 2026, which isn't an API change (0). No dated entries in the last 90 days (0). No public changelog. Support is by email, which we didn't test (3). The official Python client hasn't changed since 30 March 2020 (0). Nothing current to judge package health by (0). The status page shows the service is run and watched, which this checklist doesn't capture. 0+0+3+0+0 = 3.

Nominatim 60

Release 5.3.3 on 14 October 2026, 23 days before this check (30). Only one release in the 90 days from 8 August, against 106 commits on the default branch; commits aren't counted as releases (0). Commits from the lead maintainer and seven or more contributors since August, but we couldn't read issue reply times (12). The nominatim-api Python library is current with the server (10). CI on every push, current PostgreSQL and Python versions (8). 30+0+12+10+8 = 60.

Payments & pricing Nominatim +30

LocationIQ 30

No x402, MPP or L402 (0). Public plan prices with daily or monthly quotas, but no per-request price or overage rate, since requests over quota are refused (10). Free plan of 5,000 requests a day with no card, and commercial use allowed with a prominent link back (20). Signup is a browser flow (0).

Nominatim 60

Self-hosted rule. No payment protocol (0). Free software with nothing to buy (20 + 20 + 20). The public instance is also free and keyless, within its usage policy. 0+20+20+20 = 60.

Schema & documentation LocationIQ +27

LocationIQ 78

OpenAPI 3.0.0 spec, version 1.5.1 on 4 November, at docs.locationiq.com/openapi.yaml, covering search, reverse, autocomplete, nearby, directions, matrix, /optimize and the rest, with 429 responses defined (25). docs.locationiq.com/llms.txt indexes about 50 pages, mostly as .md (10). The reference describes each endpoint and parameter (12). Typed parameters in the spec (12). An errors page with the exact message string for each code (14). v1 in the path and a versioned spec, but no changelog (5).

Nominatim 51

No OpenAPI or machine-readable contract (0). nominatim.org/llms.txt returns 404, and the manual is HTML, though its Markdown sources sit in the repository's docs folder (0). The API reference explains each endpoint and parameter and when not to use one, such as the details endpoint being for debugging (14). Types, enums and limits are documented, such as format, layer and limit (at most 40), but there's no schema to validate against (12). Example queries and outputs per endpoint, with errors described in prose (10). A versioned manual per release, a ChangeLog and a migration guide (15). 0+0+14+12+10+15 = 51.

Security & auth LocationIQ +5

LocationIQ 55

Separate tokens per application, each with scopes, HTTP referrer or IP restrictions (up to 5 CIDRs), its own rate limits, and rotation from the dashboard, which earns 30. Less 10 because the OpenAPI spec defines only the key query parameter. The free plan gets one token (20). Scopes and per-token limits give least privilege, and nothing writes (17). Results are OpenStreetMap-derived text with no prompt-injection guidance (7). The /balance endpoint shows remaining quota. We didn't check per-call logs (4). security.txt valid to 1 January 2028, re-read on 4 November, pointing to hello@locationiq.com. No bug bounty or certification found (7).

Nominatim 50

The server has no authentication of its own; an operator puts it behind their own proxy. The public instance takes no key and identifies callers by User-Agent or Referer (5). Every endpoint reads, so there's nothing to approve (18). Results are OpenStreetMap names and tags, community-edited text, with no prompt-injection guidance (7). Query logging to a file is available through NOMINATIM_LOG_FILE and off by default (8). SECURITY.md gives security@nominatim.org, an acknowledgement within 3 work days, a disclosure process and two years of security updates per release. No bug bounty (12). 5+18+7+8+12 = 50.

How the scores have moved

LocationIQ

Nominatim

No score change since it was listed.

Verdicts

LocationIQ

5,000 free requests a day with no card, commercial use allowed with a link back. No changelog, release notes or blog.

Nominatim

Nominatim is the open-source OpenStreetMap geocoder, free to run with a documented search, reverse and lookup API, tested releases and two years of security support per release. It has no OpenAPI spec, no built-in authentication, and the public instance allows one request a second and restricts LLM-suggested use, so agents at scale need their own server.

Before you call either

LocationIQ

  1. Use eu1.locationiq.com for European users or data
  2. Add format=json and limit=1 to keep responses small
  3. On 429 Rate Limited Second wait a second, on Rate Limited Day stop until the next day
  4. Call /balance before a large batch to see what's left of the day's quota
  5. Redact the key parameter before logging request URLs

Nominatim

  1. Don't send bulk or repeated queries to nominatim.openstreetmap.org; keep to one request a second, cache results and set an identifying User-Agent
  2. Tell the user about the OSMF usage policy before suggesting the public instance, as the policy requires
  3. For regular or large jobs, run your own Nominatim or use a commercial provider listed on the Nominatim wiki
  4. Pass format=jsonv2 or geojson and limit, since omitting format sends the request to the web UI
  5. Attribute OpenStreetMap and respect the ODbL share-alike terms when storing results

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
