History is 24 hours only, and bulk data isn't available.\n\n**Xweather Weather API.** A public OpenAPI file with 236 operations, a hosted MCP server in the official registry and a free tier of 15,000 accesses a month suit agents. REST credentials travel only in the query string, per-minute limits are unpublished, and the group terms bar commercial use of free plans and passing data to third parties unless a service description allows it.\n\n## Before you call either\n\n### Google Weather API (Maps Platform)\n\n1. Ask for only the days or hours you need, one location a call. Every call is one billable event\n2. Page with pageSize and pageToken rather than asking for 240 hours at once\n3. Check the coverage page before promising alerts. Coverage is by country\n4. Refetch rather than cache. The Maps terms give no caching window for weather content\n5. Restrict the key to the Weather API and your server IPs in the Cloud console\n\n### Xweather Weather API\n\n1. Check `success` and `error.code` on every response. Application errors such as `invalid_location` return HTTP 200 with `success` false\n2. Send `fields`, `limit` and `plimit`. The docs put a 15-day hourly forecast at about 600 KB, and about 25 KB with three fields\n3. Read `X-Cost-Tokens` after each call. Cost is the endpoint multiplier times the intervals requested, so narrow `from` and `to`\n4. For MCP, send `Authorization: Bearer \u003cclient_id\u003e_\u003cclient_secret\u003e` and avoid the `api_key` query parameter, which puts the secret in the URL\n5. Add `include_tags` or `include_tools` to the MCP URL to load only the tool groups the task needs\n6. On 429 read `Retry-After` and the `X-RateLimit-Reset-*` headers. `maxhits_min` clears at the next minute, `maxhits` at the period reset\n\n## Questions\n\n### Which is better for AI agents, Google Weather API (Maps Platform) or Xweather Weather API?\n\nXweather Weather API and Google Weather API (Maps Platform) score within a point of each other on agent readiness, 67.1 (B) and 66.8 (B). Google Weather API (Maps Platform) leads on reliability and security \u0026 auth.\n\n### Do Google Weather API (Maps Platform) and Xweather Weather API need an API key?\n\nGoogle Weather API (Maps Platform) needs an API key. Xweather Weather API takes an API key or an OAuth sign-in.\n\n### Can an agent call Google Weather API (Maps Platform) and Xweather Weather API without installing anything?\n\nYes. Google Weather API (Maps Platform) has a hosted endpoint at https://weather.googleapis.com/v1 and Xweather Weather API at https://data.api.xweather.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/google-weather-api-vs-xweather.json, and with the fewest tokens: https://www.anchorterminal.com/compare/google-weather-api-vs-xweather.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"google-weather-api\", \"b\": \"xweather\"}`.
