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.\n\n**Similarweb.** The V5 API returns traffic estimates, keyword clicks and SERP positions with selectable metrics, and the hosted MCP server accepts OAuth with a read scope. Access needs a Business, Enterprise or API-only subscription sold through sales, with no API trial, public price per credit or public status page found.\n\n## Before you call either\n\n### Keywords Everywhere API + MCP\n\n1. Send the key as `Authorization: Bearer \u003ckey\u003e` to `https://api.keywordseverywhere.com/v1`. The same key works on the MCP server\n2. Call `GET /v1/account/credits` (free) before a large pull. A short balance returns 402 with `402 Insufficient Credits`\n3. 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\n4. Batch up to 100 keywords in one `get_keyword_data` call and set `country`. Without it the figures are global\n5. Keep MCP use under 120 tool calls a minute per account, and wait a minute after a Too many requests error\n\n### Similarweb\n\n1. Send the key in the `api-key` header. The capabilities endpoint documents `?api_key=` in the URL, which puts the secret in logs\n2. Stay under 10 requests a second. A 429 can also mean the monthly credit allowance is spent, so call `/capabilities` (free) before retrying\n3. Pass domains in lower case without `www.` or a path. The docs list 401 as data not found for a malformed domain\n4. Request only the metrics, countries and months needed. Credits multiply across domains, metrics, countries and periods, and daily granularity costs about 30 times monthly\n5. Website keywords accept monthly granularity for the last three months only, and `position` isn't returned for worldwide\n\n## Questions\n\n### Which is better for AI agents, Keywords Everywhere API + MCP or Similarweb?\n\nKeywords Everywhere API + MCP scores 47.2 (D) on agent readiness against Similarweb's 46 (D), and leads in 4 of 7 scored categories.
