Third-Party API Rate Limiting on Replit
Third-party API returns 429 Too Many Requests. You're hitting rate limits and requests are being rejected.
Replit apps can generate many rapid requests, quickly hitting API quotas.
Error Messages You Might See
429 Too Many Requests
rate_limit_exceeded
Too Many Requests - rate limit exceeded
Common Causes
- No request throttling or delay between calls
- Multiple API calls per user action instead of batch
- Testing with production API key (low rate limits)
- Concurrent requests without queuing
- Missing exponential backoff on retries
How to Fix It
Implement exponential backoff for retries. Use request queuing (RxJava, RabbitMQ). Cache API responses aggressively. Batch requests where possible (e.g., /api/v1/users?ids=1,2,3). Use development API tier with higher limits for testing. Monitor Replit logs for rate limit headers (Retry-After).
Real developers can help you.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

Get HelpFrequently Asked Questions
How do I implement exponential backoff?
Wait 1s, 2s, 4s, 8s between retries. Stop after max attempts
Can I increase API rate limits?
Check API provider's pricing tier. Development tiers often have low limits
