ArcGIS Location Platform vs Geocodio

ArcGIS Location Platform 61

No OpenAPI description was found for geocoding, places or routing. The geocoding service description at GeocodeServer?f=pjson lists each parameter with its type, allowed values and supported operations, which earns 8 of 25. /llms.txt returns 404 on developers.arcgis.com and location.arcgis.com (0). The reference explains when to use a direct request or a job, and stored or unstored geocoding (16 of 20). Parameters carry types, defaults, allowed values and maximums, such as maxLocations up to 50 and pageSize up to 20 (12 of 15). Each operation has request and response examples, and the geocoding output page lists error codes with extended codes and causes (13 of 15). Geocoding has dated release notes back to 2023 and the platform has release notes by month, but the geocoding path carries no version while places uses /v1 (12 of 15). Total 61.

Geocodio 92

OpenAPI 3.0.1 spec, version 2.1.0, with 11 paths (25). llms.txt and an AGENTS.md written for agents (10). llms.txt and AGENTS.md say when to use each endpoint and when not to, such as the Lists API over looping single calls, the upload tool for a one-off spreadsheet and straightline over driving distance unless road distance is needed (19). Typed parameters with country values, component fields and documented limits, though fields is a comma-separated string (12). Error table with retry guidance, examples throughout, but the spec documents 200, 400, 403, 404, 422 and 424 and not 429 or 500 (11). Versioned paths from v1 to v2.1 and a dated public changelog with entries back to 2024 (15). 25+10+19+12+11+15 = 92.

ArcGIS Location Platform 69

A closed service with a dated agreement that states what may be stored, cached and shared, and an Apache-2.0 client library (15 of 30). The privacy statement was revised on 31 July 2026, the Products & Services supplement on 9 September 2025 and the Data Processing Addendum on 12 March 2024. None states a retention period, and neither the supplement nor the addendum names ArcGIS Location Platform (14 of 30). The agreement promises 90 days' notice for deprecations, and the July 2026 release notes record the retirement of legacy API keys (16 of 20). The addendum names four sub-processors as examples and the GDPR page says information is stored in the United States, with no list specific to this product (9 of 20). Total 54.

Geocodio 87

Editorial half only. Closed service with clear, dated terms under Virginia law, and libraries and CLI under MIT (20). The privacy policy says API and spreadsheet input and results are deleted within 45 days, error logs kept 90 days, and customer data isn't used to train AI models. A separate data retention policy and llms.txt put Lists API data at 72 hours. Results may be stored permanently by the customer (27). Replaced API versions are guaranteed for at least 12 months, breaking changes come only with a new version, and the changelog marks each one 'Breaking' (18). The privacy policy names its processors, such as Sentry and Laravel Nightwatch, and the security page says self-serve is hosted in Europe (15). 20+27+18+15 = 80.

ArcGIS Location Platform 64

API key credentials carry selected privileges, an expiry date of at most one year, optional referrer limits and two tokens for rotation, and OAuth 2.0 user and app authentication are supported, which earns 30. Less 10 because the documented examples send the token as a token request parameter, although headers are accepted and recommended (20). Privileges are chosen per key, down to stored or unstored geocoding and simple or optimised routing, and the MCP server filters tools by them (16 of 20). Results include place names and addresses from third-party data, and no prompt-injection guidance was found (5 of 15). The dashboard shows usage by service and by credential per day, with no per-call log found (10 of 15). The trust centre has a coordinated disclosure programme with a safe harbour statement and a PGP key, and says Online Services are covered by FedRAMP moderate and ISO 27001, without naming ArcGIS Location Platform. No security.txt (404 on developers.arcgis.com and location.arcgis.com on 2 November) and no bug bounty were found (13 of 20). Total 64.

Geocodio 58

Revocable keys, five on pay-as-you-go, each with permissions (Lists and Distance off by default), which earns 25. Less 10 because the docs say 'All requests require &api_key=YOUR_API_KEY' and the OpenAPI spec defines only the query scheme, though an Authorization header has worked since March 2025 (15). Per-key permissions limit what a key can reach. DELETE on lists and distance jobs needs no confirmation (13). Results are addresses and government district, census and legislator data rather than user-written text. No prompt-injection guidance found (9). Usage per API key in the dashboard, downloadable as CSV, and billable-lookup headers on every response (8). Valid security.txt to 30 January 2030 with a PGP key and a responsible disclosure policy. SOC 2 Type II and annual penetration tests apply to the Enterprise platform only. No bug bounty found (13). 15+13+9+8+13 = 58.
