AI Doctor - Fix OpenAI 429 Errors, Timeouts & Streaming Issues

Works across OpenAI, Claude, Gemini, OpenClaw, LangChain, and other LLM stacks.

Fix common LLM API errors like 429 rate limits, timeouts, streaming hangs, retry loops, and runaway token costs.

AI Doctor scans your codebase and shows exactly what is breaking - then helps you fix it automatically.

Works with

Providers

• OpenAI API
• Anthropic Claude API
• Google Gemini API
• Grok
• OpenRouter
• Together AI
• Fireworks AI
• Replicate
• DeepSeek, Mistral, Cohere (OpenAI-compatible)

Frameworks & SDKs

• OpenClaw
• LangChain
• Vercel AI SDK
• LlamaIndex
• Custom OpenAI-compatible clients
• Node.js / JavaScript backends

Quick start

npx ai-doctor

Takes ~30 seconds. No config needed.

What AI Doctor detects & fixes

Rate limits (429 errors)

• Fix OpenAI 429 RESOURCE_EXHAUSTED
• Fix LangChain / OpenClaw retry issues
• Add exponential backoff + jitter
• Handle Retry-After correctly

Timeouts & hanging requests

• Fix context deadline exceeded
• Fix Vercel AI SDK timeout issues
• Prevent stuck API calls
• Add safe timeout guards

Streaming issues (SSE problems)

• Fix OpenAI / Claude streaming hangs
• Fix incomplete responses
• Fix SSE not flushing correctly
• Detect broken streaming pipelines

Retry problems

• Fix retry storms in LangChain / custom code
• Add retry limits
• Prevent infinite loops

Cost issues

• Prevent runaway token usage
• Fix missing or incorrect max_tokens
• Reduce unexpected cost spikes

Debugging & traceability

• Add request IDs
• Fix missing correlation IDs
• Improve logging for production debugging

Common errors this helps with

• 429 RESOURCE_EXHAUSTED
• context deadline exceeded
• socket hang up
• ECONNRESET
• 504 Gateway Timeout
• streaming response stuck / incomplete
• OpenAI timeout errors
• Claude streaming issues
• Gemini API failures
• LangChain retry bugs
• OpenClaw streaming / retry issues

Why use AI Doctor?

Most AI apps break in the same ways:

• Bad retry logic -> 429 errors + rate limits
• No timeouts -> requests hang forever
• Broken streaming -> partial responses
• No token limits -> runaway costs
• No tracing -> hard to debug production issues

AI Doctor finds all of this automatically.
