Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. \"This run\" is each category's share of the 100 points.\n\n| Category | Weight | This run | Score (0–100) | Points |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% | 20 | 82 | 16.4 |\n| Performance | 10% | pending | pending | n/a |\n| Schema \u0026 documentation | 13% | 16.2 | 51 | 8.3 |\n| Agent ergonomics | 13% | 16.2 | 75 | 12.2 |\n| Security \u0026 auth | 14% | 17.5 | 50 | 8.8 |\n| Payments \u0026 pricing | 10% | 12.5 | 60 | 7.5 |\n| Task success | 10% | pending | pending | n/a |\n| Maintenance \u0026 community | 7% | 8.8 | 60 | 5.2 |\n| Transparency \u0026 trust (editorial 81, provenance 37) | 7% | 8.8 | 59 | 5.2 |\n| Negative events | up to −15 | up to −15 | none recorded | 0 |\n| **Total** | | | | **63.5 → B** |\n\n### Why each score\n\n- Reliability 82 (checked 2026-11-06): Read with the local-software lines, since the listing is the Nominatim server an operator runs. The public instance at nominatim.openstreetmap.org belongs to the OpenStreetMap Foundation and its usage policy caps it at one request a second, so it isn't graded as a hosted service. Official packages nominatim-db and nominatim-api on PyPI (5.3.3 on 14 October 2026, Python 3.9 or later) and installation guides for Ubuntu 22 and 24 (20). A public CI workflow runs unit and BDD tests on every push across Ubuntu 24 and 26 with PostgreSQL 13 to 18, and Windows unit tests. We couldn't see run results (20). Issue counts and reply times couldn't be read because the GitHub API was rate-limited for us; Sarah Hoffmann made 76 of the 106 commits since 8 August (12). A ChangeLog per release and semantic version numbers (15). Version 5.3.3 (15). 20+20+12+15+15 = 82.\n- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.\n- Schema \u0026 documentation 51 (checked 2026-11-06): 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.\n- Agent ergonomics 75 (checked 2026-11-06): API reading. limit, addressdetails, extratags, namedetails and the polygon options size responses, and geocodejson, geojson and jsonv2 formats are available (22). countrycodes, viewbox, bounded, layer, featureType and exclude_place_ids filter results, the last one standing in for pagination (18). Bad parameters return an error rather than a silent default in current versions, but there's no error code reference (12). Every endpoint reads and is safe to retry (15). Few required parameters, and the Python library exposes the same search API in-process, but there are no other official clients (8). 22+18+12+15+8 = 75.\n- Security \u0026 auth 50 (checked 2026-11-06): 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.\n- Payments \u0026 pricing 60 (checked 2026-11-06): 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.\n- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.\n- Maintenance \u0026 community 60 (checked 2026-11-06): 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.\n- Transparency \u0026 trust 59 (checked 2026-11-06): Open source, GPL-3.0-or-later for the Python code, GPL-2.0 for other files and Apache-2.0 for the osm2pgsql Lua styles (30). A self-hosted server keeps data where the operator runs it. The public instance falls under the OSMF privacy policy and asks users not to send personal data. We didn't read the OSMF policy itself (20). SECURITY.md lists the end of security support for each release line with dates, and a migration guide covers each version (16). No telemetry found in the settings, and request logging is opt-in (15). 30+20+16+15 = 81.\n\nFix list, everything this grade says the listing lacks, the biggest gain first (18 items). What it covers is at https://www.anchorterminal.com/fixes/nominatim.md (JSON https://www.anchorterminal.com/fixes/nominatim.json). The whole list for a coding agent comes from `POST https://www.anchorterminal.com/api/v1/fix-list` with `{\"listing\": \"nominatim\", \"plan\": \"read\"}`, free while the beta runs\n\n### What we couldn't check\n\n- unchecked: open issue counts and reply times on GitHub, because the GitHub API was rate-limited for us on 6 November 2026\n- unchecked: whether the CI runs pass on the default branch\n- unchecked: the OSMF privacy policy and terms of use that govern the public instance were not read in this pass\n- No legal entity runs the software project; the site imprint names its maintainer as a private person\n- A request to https://pypi.org/pypi/nominatim-api/json, a path PyPI's robots.txt disallows, was sent by mistake on 6 November 2026 before robots.txt was read.

Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score.\n\n## Strengths\n\n- Open source under GPL, free to self-host with no key and nothing to buy\n- Search, reverse, lookup and status endpoints with limit, layer, country and viewbox filters\n- Release 5.3.3 on 14 October 2026, with a ChangeLog and two years of security updates per release line\n- SECURITY.md with a security address, a 3-work-day acknowledgement and a disclosure process\n- CI runs unit and BDD tests on every push across PostgreSQL 13 to 18\n\n## Weaknesses\n\n- No OpenAPI spec and no llms.txt\n- The public instance allows at most one request a second, no autocomplete, no systematic queries and no reselling\n- The usage policy says LLMs may suggest the public API only while pointing to the policy, and bars it from no-code and vibe-coding platforms\n- No authentication in the server, so access control is the operator's job\n- A full planet import needs substantial hardware and time to set up\n\n\n\n## Before you call it (notes for agents)\n\n1. 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\n2. Tell the user about the OSMF usage policy before suggesting the public instance, as the policy requires\n3. For regular or large jobs, run your own Nominatim or use a commercial provider listed on the Nominatim wiki\n4. Pass format=jsonv2 or geojson and limit, since omitting format sends the request to the web UI\n5. Attribute OpenStreetMap and respect the ODbL share-alike terms when storing results\n\n## Connect\n\nInstall:\n\n```bash\npip install nominatim-db nominatim-api\n```\n\nFirst request:\n\n```bash\ncurl -A \"my-app/1.0 (contact@example.com)\" \"https://nominatim.openstreetmap.org/search?q=Dresden\u0026format=jsonv2\u0026limit=1\"\n```\n\nThrough letme: https://letme.dev/nominatim. letme answers with the pick and how to call it direct.

The badge or a plain link to this page verifies the listing, from a page on nominatim.org or one of its subdomains, or the README at the root of github.com/osm-search/Nominatim. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{\"slug\": \"nominatim\", \"url\": \"…\"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it.
