AgentSEO

You create an API key and can try the endpoints in a playground or mock mode before spending live credits. The site shows a full request and a labelled example response for each workflow, so you can check the response shape before you sign up.

From there you call a workflow from your own code or agent. A local visibility check takes a domain, keywords and locations and returns a visibility score with per-query snapshots and suggested next actions. A content gap audit takes a URL and a keyword, fetches the competing SERP results, extracts their heading outlines and returns the missing topics plus a markdown summary, in one call.

Each endpoint costs a set number of credits: a search of up to 10 results is 1 credit, an agent QA workflow 2, a SERP-informed outline 4 and a content gap audit 10. Mixed workloads draw on one monthly allowance, and when it runs out the plan stops rather than billing extra. Your agent decides what to do with the result; AgentSEO keeps the response contract the same.

• •Search and Rank Tracking - SERP analysis, keyword and URL rank tracking, local visibility by city and volatility checks, returned as selected fields with ranking context rather than whole pages.
• •Keyword and Competitor Research - Keyword ideas, metrics and clustering, ranked keywords for a domain, competing domains, keyword intersections and traffic estimates for planning content.
• •Content Workflows - Content gaps, briefs, outlines, keyword maps, internal link suggestions, refresh plans, content decay detection, schema plans and pre-publish QA, each with a documented output shape.
• •AI Visibility Tracking - AI Overview extraction, prompt-set tracking and LLM mention tracking, alongside backlink analysis and social listening, for teams that want to know whether AI assistants cite them.
• •MCP Server, REST and SDKs - One contract across REST, the Node.js and Python SDKs and an MCP server, with integration guides for n8n, Codex, OpenClaw and Claude Desktop.
• •Agent-Friendly Responses - Deterministic JSON, type-safe inputs, a markdown_summary on every response, idempotency-key support for safe retries and predictable error payloads with request IDs. The vendor reports 72.6% smaller enriched payloads in a bounded three-query comparison and says plainly that this is not a token or cost guarantee.

AgentSEO suits developers building SEO agents or internal tools who want search data an LLM can read without trimming it first. A solo builder can wire a content decay check into a weekly cron job, and a team running an agent in Claude or Cursor can give it rank and keyword data through the MCP server.

Vibe marketers and technical SEOs who already automate with n8n get workflows such as content gap audits and local visibility checks that return a ready summary for Slack or a ticket. Agencies managing several client sites can run recurring rank and visibility reports on the Agency plan, which adds reserved throughput, multi-client workflows and a dedicated Slack channel.

It is less suited to someone who wants a point-and-click SEO suite, since everything happens through API calls.
