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).

I build and fix web apps across Next.js, Node.js, and DBs.
Comfortable jumping into messy code, broken APIs, and mysterious bugs.
If your project works in theory but not in reality, I help close that gap.

Full-stack developer experienced in fixing and deploying AI-generated apps from Lovable, Bolt.new, Cursor, and Replit. I specialize in debugging Supabase integration issues (auth flows, RLS policies, database connections), fixing broken deployments, resolving routing/blank screen problems, and cleaning up messy React/Vite codebases. I also build production apps with the Claude API and have shipped a Mac desktop dev tool (Nexterm from scratch. Based in Hong Kong, fast turnaround.
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.

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
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
