Learn how to measure Claude API token consumption and implement usage-based billing with Stripe Meter Events. A minimal Node.js setup that indie developers can ship in a weekend, with real gotchas from production.
Building an Offline-Capable AI Notes App with Claude API and Local-First Sync — A Production Design with Replicache and IndexedDB
A production design guide for combining Claude API with a local-first sync engine. Walks through Replicache, IndexedDB, mutation queues, and idempotency keys with full TypeScript code.
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.
Stop Claude API Prompt Regressions with Golden-Dataset Testing
A complete production guide to catching the silent quality drift that hits Claude API prompts when models or prompts change — using golden datasets and LLM-as-a-Judge wired into CI.
Claude API Telemetry on ClickHouse: A Production Guide to Cost, Latency, and Error Analytics
Stream per-request Claude API telemetry into ClickHouse, build sub-second dashboards with materialized views, and detect cost spikes, retry loops, and silent failures with practical SQL recipes.
Building a Production Claude API Pipeline on Cloudflare Queues: Fault Tolerance, Backpressure, and Cost Control
A practical, code-first walkthrough for routing Claude API calls through Cloudflare Queues — covering producer/consumer code, retry-vs-DLQ branching, priority lanes, and token budgeting for production workloads.
Infrastructure Requirements for Claude API Deployment: Sizing, SLA, and Compliance Decisions Before Production
Your prototype works. But what does 'production-ready' actually mean? This guide walks through how to derive infrastructure requirements from traffic, SLA, and data-residency decisions — with concrete numbers and a sizing formula.
Production Semantic Cache for Claude API — Similarity Thresholds, Pollution Defense, and What to Track
A production playbook for adding a semantic cache in front of Claude API — threshold tuning, multi-tenant isolation, pollution prevention, fallbacks, how it stacks with Anthropic's prompt caching, and the metrics that actually prove it works.
Four Infrastructure Levers That Cut Claude API Latency Before You Touch the Model
Before you downgrade Sonnet to Haiku to chase faster responses, the network and request shape around your Claude API calls usually has more headroom. Here are four infrastructure levers — region selection, connection pooling, prompt caching, and streaming — with code and measurement notes.
Building a Recurring Billing SaaS with Claude API and Stripe — From Architecture to Production
A complete architecture guide for building a SaaS product powered by Claude API with Stripe recurring billing. Covers usage metering, tiered pricing, webhook handling, and production deployment patterns.
Production-Grade Hallucination Defense for Claude API: A Multi-Layer Architecture
Prompt engineering alone is not enough to suppress hallucinations in production. After a real customer incident, I rebuilt the system around four defensive layers — input grounding, tool-use escape hatches, citations, and post-hoc verification. This is the implementation playbook.
Replay-Driven Testing for Claude API: A Production Pattern for Recording and Replaying Responses
A production-grade design for stabilizing Claude API tests by recording and replaying real responses. Covers cassettes for Messages, Streaming, Tool Use, CI integration, and incident replay.
