Your API Docs Are Invisible in AI Search

When developers ask Claude "how do I implement webhooks" or ChatGPT "show me payment API examples", your documentation doesn't surface. Stripe, Twilio, and SendGrid do. Waldium makes your API discoverable where developers actually search.

THE PROBLEM

This Is Happening Right Now

When developers ask AI for API recommendations, your documentation doesn't show up in the conversation.

AI
ChatGPT
Developer's AI assistant
"For payment processing APIs, I'd recommend Stripe for its comprehensive documentation and easy integration, LemonSqueezy for SaaS subscriptions, or Paddle for global payments. All three have excellent developer guides and code examples."
→ Your payment API? Not in the conversation. Stripe's documentation surfaces first.
THE INVISIBLE PROBLEM

You're Invisible Where Developers Actually Search

When developers ask "how do I implement X", AI systems recommend your competitors' APIs because their docs are LLM-optimized. Yours aren't.

Without Waldium

  • ChatGPT recommends Stripe, Twilio, SendGrid when developers ask about APIs
  • Your API documentation is invisible in Cursor, Claude, and ChatGPT
  • Developers discover your API last, after trying 3-4 competitors
  • Documentation updates reach 50 developers via Twitter, then die
  • No visibility into which docs drive API adoption or integrations
