## Which one, for what

### Keywords Everywhere API + MCP (D)

Good for: An agent that needs Google Keyword Planner volume, CPC and competition for lists of keywords at a low price per keyword, plus keyword ideas and a quick view of a site's ranking keywords, traffic estimate and top backlinks.

Ahead on:
- Reliability, 42 against 17
- Security & auth, 47 against 32
- Payments & pricing, 20 against 15
- Maintenance & community, 63 against 22
- Transparency & trust, 68 against 53

Watch for: No free credits or trial. Data calls need an annual plan, from $84 for 100,000 credits that expire after a year

### 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.

Watch for: Clause 14.1(f) of the supply terms forbids querying Majestic's database or servers with automated tools without prior permission. This matters before any probe is run

## 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
