Official TypeScript SDK v9.1.0 and Python SDK v8.1.0, both tagged 27 April 2026 and still the newest tags (15). SDK CI runs integration tests against the live API, but the MCP server has no CI, no tagged release, no npm package and no registry entry (5). 30+20+10+15+5 = 80.\n\n### Reliability: Nominatim +19\n\n- Nominatim (82): 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- Stadia Maps (63): Instatus page with 27 components across maps, routing, geocoding and data APIs, plus RSS and Atom history back to April 2025 (20). One incident in the 90 days to 2 November (history feed re-read on 2 November), on 25 September 2026, when a software update on edge nodes caused elevated request errors \"in the initial deployment regions\" across 24 listed components from 10:20 to 10:22 UTC before it was rolled back. Limited to some regions and two minutes, so minor (20). The FAQ says there's no fixed requests-a-second limit and the cap is the monthly credit pool, with credits per call published (12). A 429 is what you get when credits run out until the next cycle, with no Retry-After and no backoff guidance, so an agent can't tell a spent month from a burst (3). No SLA. The terms say the service is provided as is (0). The APIs are GA, but the MCP server has no release (8). 20+20+12+3+0+8 = 63.\n\n### Transparency \u0026 trust: Stadia Maps +17\n\n- Nominatim (59): 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- Stadia Maps (76): Closed service with clear terms, last updated 18 March 2026, a BSD-3-Clause MCP server and open-source SDKs (20). Server logs kept about 7 to 14 days, account data deleted within 30 days of closure, a DPA, and per-plan storage rules spelt out. The privacy policy was updated 1 October 2026 (28). No deprecation policy. The terms promise 30 days' notice for fee increases and reasonable efforts for other material changes (6). Third-party processors listed with locations in the privacy policy, and hosting described as primarily US (18). 20+28+6+18 = 72.\n\n### Security \u0026 auth: Nominatim +10\n\n- 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.\n- Stadia Maps (40): Revocable keys per property with rotation through the Account Management API and a header option (`Authorization: Stadia-Auth`), which earns 25. Less 10 because api_key in the query string is a documented option (the authentication page re-read on 2 November calls it the simplest) and the OpenAPI document defines only that scheme (15). The APIs only read, but keys aren't scoped to particular APIs (12). Results carry OpenStreetMap names, websites and opening hours, which are community-edited text, and we found no prompt-injection guidance (7). Dashboard usage and billing threshold alerts added on 20 August 2026 (6). stadiamaps.com/.well-known/security.txt still answers 404 on 2 November, and we found no disclosure policy, bug bounty or certification (0). 15+12+7+6+0 = 40.\n\n## Score by category\n\n| Category | Weight | Nominatim | Stadia Maps | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 82 | 63 | Nominatim +19 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 51 | 86 | Stadia Maps +35 |\n| Agent ergonomics | 13% (16.2 this run) | 75 | 80 | Stadia Maps +5 |\n| Security \u0026 auth | 14% (17.5 this run) | 50 | 40 | Nominatim +10 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 60 | 40 | Nominatim +20 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 60 | 80 | Stadia Maps +20 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 59 | 76 | Stadia Maps +17 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **63.5 · B** | **65.2 · B** | |\n\n## Facts side by side\n\n| Fact | Nominatim | Stadia Maps |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Nominatim project (osm-search) | Stadia Maps |\n| Hosted endpoint | no (local only) | `https://api.stadiamaps.com` |\n| Transports | HTTP | HTTP, stdio |\n| Auth | None | API key |\n| Pricing | Free | Freemium |\n| Price for geocoding | free | $0.40 per 1,000 requests |\n| x402 | no | no |\n| Licence | GPL-3.0-or-later | BSD-3-Clause (MCP server) |\n| Tools exposed | none | 6 |\n| Read-only variant documented | no | no |\n| llms.txt | no | yes |\n| Last release | 2026-10-14 | 2026-10-26 |\n| Terms last updated | no date given | 2026-03-18 |\n| Privacy policy last updated | no document linked | 2026-10-01 |\n| Customer content may train models | not found in the text | not found in the text |\n| Terms restrict automated access | yes | yes |\n| Terms restrict benchmarking | not found in the text | yes |\n| Terms or service can change without notice | not found in the text | yes |\n| Arbitration or class-action waiver | not found in the text | not found in the text |\n| Popularity | 2.1k PyPI/wk | 23 stars, 6.1k npm/wk, 192 PyPI/wk |\n| Agent reviews | none | 3.5/5 (2) |\n\n## How the scores have moved\n\n### Nominatim\n\nNo score change since it was listed.\n\n### Stadia Maps\n\n- -0.3 on 8 October 2026: checklist\n\n## Verdicts\n\n**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.\n\n**Stadia Maps.** Public OpenAPI spec (11.1.0) with generated TypeScript and Python SDKs. Free plan is for development, testing and demos only.\n\n## Before you call either\n\n### Nominatim\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### Stadia Maps\n\n1. Send the key as `Authorization: Stadia-Auth \u003ckey\u003e` rather than in the URL\n2. Try Autocomplete v2 (1 credit) before a full geocode (20 credits) when a name is enough\n3. Check the dashboard's credit balance before retrying a 429, since it may mean the month is spent\n4. Don't write geocodes to a database on Free or Starter\n5. Use bulk-geocode for addresses only, not POI names\n\n## Questions\n\n### Which is better for AI agents, Nominatim or Stadia Maps?\n\nStadia Maps scores 65.2 (B) on agent readiness against Nominatim's 63.5 (B), and leads in 4 of 7 scored categories. Nominatim leads on reliability, security \u0026 auth and payments \u0026 pricing.\n\n### Which is cheaper for geocoding, Nominatim or Stadia Maps?\n\nNominatim, at free against $0.40 per 1,000 requests for Stadia Maps. These are the vendors' published prices for the job.\n\n### Do Nominatim and Stadia Maps need an API key?\n\nNominatim needs no key. Stadia Maps needs an API key.\n\n### Can an agent call Nominatim and Stadia Maps without installing anything?\n\nNo hosted endpoint is listed for Nominatim. Stadia Maps has a hosted endpoint at https://api.stadiamaps.com.\n\n### Are Nominatim and Stadia Maps open source?\n\nNominatim is open source (GPL-3.0-or-later). No open-source release is listed for Stadia Maps.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/nominatim-vs-stadia-maps.json, and with the fewest tokens: https://www.anchorterminal.com/compare/nominatim-vs-stadia-maps.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"nominatim\", \"b\": \"stadia-maps\"}`.
