Connect AI Agents, Claude MCP & Custom GPTs to Live Domain Availability

LLMs hallucinate unregistered domains because their training weights cannot query live TLD zones. Plug TLDMint into Claude, Cursor, Windsurf, ChatGPT Actions, or any HTTP agent to generate niche domains, verify real-time DNS delegation, and return direct checkout links with Year-1 promo codes.
