Status Code Error 429
The 429 “Too Many Requests” error disrupts AI agents, LLMs, and autonomous systems that interact with APIs and web data. When your AI application exceeds rate limits, it stops real-time operations and breaks agent workflows. This guide shows you how to build resilient AI systems using Bright Data’s infrastructure.
- 150M+ IP distribution
- Automatic retry handling
- 99.95% success rate
- Zero rate-limit management
How AI Agents Encounter 429 Errors
AI agents and autonomous systems face unique rate-limiting challenges due to their continuous operation and high request volumes. Understanding these scenarios helps you build more resilient AI applications.
Autonomous AI Agents
Modern AI agents make continuous API calls to retrieve information and make decisions. A single agent can send hundreds of requests per minute when gathering real-time data or executing multi-step workflows.
LLM Applications
AI applications built on language models hit rate limits quickly. Embedding generation for vector databases triggers 429 errors when processing large document sets.
Training Data Collection
AI model training requires massive datasets from various sources. Collecting real-time data for RAG knowledge bases often exceeds server rate limits.
Multi-Agent Systems
When multiple AI agents operate simultaneously, they multiply the request load. This quickly exceeds rate limits and triggers 429 errors across your entire system.
Research and Intelligence Tools
Competitive intelligence agents and market research bots monitor multiple data sources continuously. This constant activity frequently hits rate limits.
Bright Data Solutions for AI Agents
Bright Data provides purpose-built infrastructure that eliminates rate limit issues for AI applications. Our APIs handle retry logic, IP rotation, and request distribution automatically so you can focus on building AI functionality.
Web Unlocker API
Web Unlocker handles 429 errors automatically with intelligent retry logic. It manages IP rotation and request distribution without any configuration from you.
The API delivers a 99.95% success rate for uninterrupted AI agent operations. It integrates directly with popular frameworks like LangChain and LlamaIndex.
SERP API for AI Search
SERP API enables AI agents to search without hitting rate limits. Get results from Google, Bing, and DuckDuckGo through a single endpoint.
The API returns structured JSON responses ready for LLM consumption. No need to manage search engine rate limits or solve CAPTCHAs.
Scraper APIs
Scraper APIs handle rate limiting for 100+ websites automatically. Get structured data from LinkedIn, eCommerce sites, and social media without infrastructure management.
Use Scraper Studio to build custom data pipelines for your specific AI needs.
Datasets for Training
Datasets let you bypass rate limits entirely with pre-collected data. Access structured datasets ready for immediate AI training.
The Web Archive provides 50+ petabytes of historical web data. Perfect for fine-tuning LLMs and building RAG knowledge bases.
Browser API
Browser API enables AI agents to interact with dynamic websites. It includes automatic rate limit handling and built-in stealth mode to prevent detection.
Ideal for AI agents that need to navigate multi-step workflows or execute JavaScript.
Crawl API
Crawl API turns entire websites into AI-friendly data. It handles intelligent rate limiting automatically while crawling from single pages to millions of URLs.
The API converts websites into structured data ready for AI processing.
MCP Server
The Bright Data MCP Server provides a free toolkit for AI agents and applications. It offers unified access to all Bright Data capabilities through the Model Context Protocol.
Works with Claude, ChatGPT, and other AI assistants out of the box.
Native AI Integrations

Pre-built tools and document loaders speed up AI development.
Proxy Infrastructure for Custom AI Agents
For developers building custom AI agent infrastructure, our proxy network provides the flexibility and scale needed to avoid rate limits while maintaining full control over your architecture.
Residential Proxies
Residential proxies provide 150M+ IPs from real devices globally. Automatic IP rotation prevents 429 errors when building custom AI agent infrastructure.
Sticky sessions maintain agent context across requests. Geographic targeting ensures agents access region-specific data.
ISP and Datacenter Proxies
ISP proxies combine residential trust with datacenter speed. Datacenter proxies deliver maximum throughput for high-frequency operations.
Static IPs work best for AI agents requiring consistent identity. Perfect for real-time monitoring agents and high-speed data collection.
