Building a Budget Circuit Breaker for Claude API in Production — Auto-Halt When Daily Token Spend Exceeds Your Cap
A practical guide to enforcing daily and monthly Claude API budget caps in production. Includes copy-paste Cloudflare Workers + KV / Durable Objects code, three response strategies (halt, degrade, alert), and the operational habits that keep the breaker honest.
High-Availability Patterns for the Claude API — Making Sonnet/Haiku/Opus Fallback Work in Production
A single-model Claude API integration will fall over the first time rate limits or a regional hiccup land at peak hours. This is the production pattern for a Sonnet → Opus → Haiku fallback chain, with circuit breakers, streaming coverage, and the pitfalls you only learn the hard way.
Claude API Production Resilience Patterns — Model Routing, Circuit Breakers, and Fallback Strategies for Indie Teams
Production resilience patterns for Claude API: circuit breakers, intelligent model routing, fallback chains, exponential backoff with jitter, and disaster recovery — with TypeScript implementations and operational notes from an indie developer.
When a Connector Starts Slowing Down at Night: A Health-Aware Circuit Breaker for Solo Automation
Seeing connector errors and latency is only half the job — the other half is deciding when to route around them. This is my implementation of a circuit breaker that opens on error rate and p95, with runnable Python and notes on wiring it into nightly jobs.
