API access starts at $399.99 a month with no trial, and no OpenAPI file, status page, numeric rate limit, SLA or API changelog was found. The supply terms require permission before querying with automated tools.\n\n**SE Ranking API + MCP.** Every Data API endpoint has a published credit cost, credits sell from $50 for 250,000 with no expiry, and a 14-day trial needs no card. Keys carry full account access with no scopes or read-only mode, the key may travel in the URL, and no security page, SLA or llms.txt was found.\n\n## Before you call either\n\n### Majestic API\n\n1. Send requests by HTTPS POST with `app_api_key` in the body. The docs show GET URLs for demonstration only and plain HTTP still works\n2. Always set `datasource=fresh` or `datasource=historic`. Without it the Historic Index is used when the plan includes it\n3. Call `GetSubscriptionInfo` (no cost) before a large pull. `GetBackLinkData` spends 5,000 analysis units a call plus one retrieval unit a row\n4. Read columns by header name, not position. The docs say column order can change between requests and Majestic may vary rows and columns at any time\n5. Develop against `https://developer.majestic.com/api/json`, which costs no units, then switch the host to `api.majestic.com`\n6. Ask the owner to confirm Majestic's permission for automated querying first. Clause 14.1(f) of the terms requires it\n\n### SE Ranking API + MCP\n\n1. Send the key as `Authorization: Token \u003ckey\u003e`, not `Bearer` and not `?apikey=`, so it stays out of URLs and logs\n2. Call `GET /v1/account/subscription` (0 credits) and read `units_left` before a large pull. A short balance returns `Insufficient funds`\n3. Set `limit` and `cols` on per-record endpoints. Backlink summaries cost 100 credits a target and keyword rows 10 credits each\n4. Stay under 10 requests a second on the Data API and 5 on the Project API per key. Repeated overruns block the Project API for 10 minutes\n5. Ask the owner before any Project API or `PROJECT_*` create, update or delete call. The key has no read-only mode and nothing confirms a delete\n\n## Questions\n\n### Which is better for AI agents, Majestic API or SE Ranking API + MCP?\n\nSE Ranking API + MCP scores 50.9 (D) on agent readiness against Majestic API's 33.4 (F), and leads in 6 of 7 scored categories. Majestic API leads on security \u0026 auth.\n\n### Do Majestic API and SE Ranking API + MCP need an API key?\n\nMajestic API needs an API key. SE Ranking API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Majestic API and SE Ranking API + MCP without installing anything?\n\nYes. Majestic API has a hosted endpoint at https://api.majestic.com and SE Ranking API + MCP at https://api.seranking.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/majestic-vs-se-ranking.json, and with the fewest tokens: https://www.anchorterminal.com/compare/majestic-vs-se-ranking.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"majestic\", \"b\": \"se-ranking\"}`.
