# Lumind > Lumind is an AI visibility (GEO) and SEO platform. It measures and improves how AI answer engines (ChatGPT, Claude, Perplexity, Gemini) cite a brand, and sells those scans to humans and to AI agents. ## For AI agents Lumind exposes a programmatic surface so an autonomous agent can buy and run scans with a capped, delegated budget. A human owner funds LUM credits and issues the agent a key with a spend cap; the agent never exceeds that cap and never handles a payment card. - API reference (OpenAPI): https://lumind.io/v1/openapi.json - Discovery document: https://lumind.io/.well-known/lumind.json - MCP server: the `lumind-mcp` package exposes the tools lumind_list_services, lumind_wallet_balance, lumind_run_scan, lumind_get_report. - Authentication: Bearer agent key (form lmd_agent_...), issued by a human owner. ## Services - GEO/SEO citation scan: a scored report of how AI answer engines cite a domain, with sources and prioritized fixes. 1900 LUM ($19). ## Pricing unit - 1 LUM = $0.01.
