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.

  4. Batch up to 100 keywords in one get_keyword_data call and set country. Without it the figures are global

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.
