PraisonAI tools are designed with reliability-first principles.

​
Search Provider Priority

Automatic Fallback

search_web tries providers in order until one succeeds

Retry Logic

Each provider retries 3 times with exponential backoff

​
Quick Start

​
Error Handling

results = search_web("query")
if results and "error" in results[0]:
    print(f"Failed: {results[0]['error']}")
System processes may return None for CPU/memory. Defaults to 0.0.

​
API Keys

ProviderEnvironment VariableQuality
TavilyTAVILY_API_KEY⭐⭐⭐ Best

Set TAVILY_API_KEY for best search quality. DuckDuckGo is the free fallback.

​
Schema-level Reliability

Runtime reliability (error handling, retries, fallbacks) complements schema-time reliability for comprehensive tool safety. Schema validation catches broken tools at development time:
  • Invalid OpenAI function schemas
  • Missing required fields like properties
  • Non-JSON-serializable values
  • Duplicate tool names in lists
Runtime reliability handles execution errors:
  • Network failures and timeouts
  • API rate limits and retries
  • Provider fallbacks
  • Process crashes
