## 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:
- Security & auth, 47 against 21

Also in its favour:
- Cheaper for keyword data, $0.0008 against $0.002 per record

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

### SE Ranking API + MCP (D)

Good for: An agent that needs keyword, backlink, domain and AI search visibility data at a published price per call, or that manages rank tracking projects for an SE Ranking customer.

Ahead on:
- Reliability, 51 against 42
- Schema & documentation, 58 against 48
- Payments & pricing, 40 against 20
- Maintenance & community, 79 against 63

Watch for: No scoped or read-only keys. The MCP docs say a key has the same access as the account, including Project API deletes

## 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

### SE Ranking API + MCP

1. Send the key as `Authorization: Token <key>`, not `Bearer` and not `?apikey=`, so it stays out of URLs and logs
2. Call `GET /v1/account/subscription` (0 credits) and read `units_left` before a large pull. A short balance returns `Insufficient funds`
3. Set `limit` and `cols` on per-record endpoints. Backlink summaries cost 100 credits a target and keyword rows 10 credits each
4. 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
5. 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
