## 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 38
- Maintenance & community, 63 against 28
- Transparency & trust, 68 against 59

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

### Moz API (E)

Good for: Agents that need Domain Authority, backlink lists, link intersects, keyword volume and difficulty, search intent and ranking keywords at a low entry price, on a read-only data set.

Ahead on:
- Agent ergonomics, 74 against 54

Watch for: No working public status page was found, and moz.statuspage.io reports the Moz Status page as inactive

## 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.

**Moz API.** The JSON-RPC API documents every error code, its rate limits and the row cost of each method, and failed validation uses no quota. No working status page, SLA, machine-readable spec or official SDK was found. Tokens carry no scopes, and the free plan needs a credit card.

## 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

### Moz API

1. Send a request `id` of at least 24 characters (letters, numbers and hyphens). A UUID works. Shorter ids are rejected with -32654.
2. Stop on a 401. Ten 401 or 403 responses in five minutes block the caller for 30 minutes.
3. On 429 with code -32658 wait the `Retry-After` seconds. On code -32650 no wait time is given, so back off exponentially.
4. Call `quota.lookup` (free) before large pulls. List methods charge one row per result, and `limit` is capped at 50 on link lists.
5. Poll `async.call.lookup` for `data.keyword.serp.generate`, and collect the result within 20 seconds of first seeing it complete.
