Claude API Pricing Guide 2026 — Complete Cost Breakdown for Every Model, Batch API, and Prompt Caching
A complete guide to Claude API pricing in 2026. Learn the per-token costs for Opus 4.6, Sonnet 4.6, and Haiku 4.5, how to save up to 95% with Batch API and Prompt Caching, and see real-world cost estimates for common use cases.
Claude API 429 Errors in Production: Lessons from Six Parallel Content Pipelines
When Claude API starts returning 429 Too Many Requests, the official exponential-backoff snippet alone is rarely enough. Drawing on six content pipelines run by one indie developer, this guide covers the real failure modes I have observed, working Python and TypeScript retry implementations with jitter, a token-bucket throttle, and concrete criteria for moving jobs to the Batch API.
