Majestic API F

Good for An agent that needs backlink, referring domain, anchor text and Trust Flow data in volume for an owner who already pays for the API plan.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

Verdicts

Keywords Everywhere API + MCP

Fourteen read-only lookups with a published credit cost each, available over REST and a hosted MCP server listed in the official registry. Data needs an annual plan from $84, with no trial. No OpenAPI file, no REST rate limit and no API changelog were found, and the status page shows outages on seven of the last 90 days.

Majestic API

Each command's cost in units is published and a sandbox endpoint returns sample data without spending allowance. 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.

Before you call either

Keywords Everywhere API + MCP

  1. Send the key as Authorization: Bearer <key> to https://api.keywordseverywhere.com/v1. The same key works on the MCP server
  2. Call GET /v1/account/credits (free) before a large pull. A short balance returns 402 with 402 Insufficient Credits
  3. Set num on domain, URL and backlink lookups. It accepts 1 to 10,000 and every returned row is charged 1, 2 or 5 credits
  4. Batch up to 100 keywords in one get_keyword_data call and set country. Without it the figures are global
  5. Keep MCP use under 120 tool calls a minute per account, and wait a minute after a Too many requests error

Majestic API

  1. 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
  2. Always set datasource=fresh or datasource=historic. Without it the Historic Index is used when the plan includes it
  3. Call GetSubscriptionInfo (no cost) before a large pull. GetBackLinkData spends 5,000 analysis units a call plus one retrieval unit a row
  4. 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
  5. Develop against https://developer.majestic.com/api/json, which costs no units, then switch the host to api.majestic.com
  6. Ask the owner to confirm Majestic's permission for automated querying first. Clause 14.1(f) of the terms requires it
