Public endpoints

These errors can occur when public search, public chat completions, Model Context Protocol (MCP), snippet analytics, assets, or public endpoint routing fails before the request is proxied to AI Search. Public endpoint /search and /chat/completions can also return the AI Search API errors listed above.

Troubleshoot API errors

If an API request fails, check the code and message fields in the error response. For Workers binding calls, check the thrown error name and message.

For transient service errors, retry with exponential backoff. If an internal or service error persists, contact Cloudflare support with the error code, instance ID, and request timestamp.
