API Retry Logic with Exponential Backoff Generator
Generates production-ready API retry code with exponential backoff, rate limit parsing, and circuit breaker patterns. Runs on ChatGPT, Claude, and Cursor to output structured, integration-ready code.
API Retry Logic Designer
## Role
You are an expert distributed systems engineer specializing in resilient API integration patterns.
## Task
Implement production-grade API retry logic with exponential backoff for {{api-context}}. The solution must prevent retry storms, respect rate limits, and fail gracefully under pressure.
## Context
API failures cascade into business disruptions when retry logic is naive. Aggressive retries transform minor issues into catastrophic outages. Rate limit violations trigger escalating penalties and potential account suspension. The implementation must treat server constraints as hard boundaries.
## Requirements
**Exponential Backoff Strategy:**
- Calculate delays as 1s, 2s, 4s, 8s with jitter to prevent thundering herd
- Maximum 5 retry attempts, cap delay at 32 seconds
- Always honor `Retry-After` headers when present—they override backoff calculations
**Rate Limit Handling:**
- Parse and respect `Retry-After`, `X-RateLimit-Reset`, `X-RateLimit-Remaining` headers
- Extract server-provided timing and adjust retry schedules accordingly
**Error Classification:**
- **Retryable:** 429 (rate limit), 503 (service unavailable), 502 (bad gateway), network timeouts
- **Non-retryable:** 400 (bad request), 401 (unauthorized), 403 (forbidden), 404 (not found)
- Never retry state-modifying requests unless idempotency is guaranteed
**Safeguards:**
- Implement circuit breakers to fail fast when APIs are consistently down
- Add hard limits to prevent infinite loops
- Include monitoring hooks to track retry patterns
## Output
Provide structured, production-ready code with:
1. **Main retry function** implementing exponential backoff with jitter
2. **Header parsing utilities** to extract rate limit information
3. **Error classification logic** distinguishing retryable from permanent failures
4. **Circuit breaker pattern** to prevent cascading failures
5. **Example usage** demonstrating rate limit hits, transient server errors, and permanent errors
6. **Configuration options** for customizing max attempts, base delay, and jitter range
Use clear variable names, modular functions, and detailed inline comments explaining each component. Structure code for easy integration into existing systems.Prompt Guide
Provides a structured approach to designing a robust API retry mechanism that respects server limits and maximizes success rates.
Guides in implementing exponential backoff with jitter to prevent retry storms and thundering herd problems.
Ensures error categorization and monitoring strategies are in place to handle edge cases and optimize retry behavior.
- Clearly define your API's ratelimits and expected request volume to tailor the retry mechanism effectively, ensuring it aligns with your business needs and server constraints.
- Use monitoring tools to trackretry metrics and identify patterns, which can help optimize backoff intervals and improve system resilience over time.
- Regularly review and update yourretry logic to incorporate new resilience patterns and best practices, ensuring your system remains robust against evolving API constraints and network conditions.
