SEO API and MCP

Backlink analysis, domain authority, and keyword research for agent workflows - without enterprise SEO tool subscriptions or maintaining scrapers.

Check domain rating and global rank for any website, pull page-level and domain-level URL metrics (backlinks, referring domains, traffic estimates, organic keywords), discover backlinks with anchor text and linking pages, and research keywords with search volume, clicks, CPC, difficulty, and traffic potential per country. Use REST at api.vee3.io or hosted MCP at mcp.vee3.io in Cursor, Claude Code, Codex, and other AI agents.

Successful calls use 10 API tokens per lookup; the country code list is free. Start on the free plan (1,000 tokens per month, no credit card), then scale from $5/month when your SEO research and content pipelines need more volume.
