How does the skill handle 429 Rate Limit errors?

The skill includes production-grade logic for exponential backoff that monitors the 'retry-after' header to gracefully handle high traffic and prevent application failures.

How much can I save with prompt caching?

By using the prompt caching patterns included in this skill, you can reduce costs for cached input tokens by up to 90% for repeated content like system prompts or large documents.

Can I use this for vision-based tasks?

Absolutely. There are dedicated templates and validation rules for processing images (JPEG, PNG, WebP) for tasks like OCR, image analysis, and visual description.

Does this skill work with Cloudflare Workers?

Yes, it provides specific implementation patterns for the fetch-based environment of Cloudflare Workers, including authentication and stream handling.

Which versions of Claude are supported?

It supports all current Anthropic models including Claude 3.5 Sonnet, 3.7 Sonnet, and Claude 4.5, with specific guidance on version pinning for stability.

API Development

Simplifies the integration of Anthropic Messages API into applications with optimized patterns for streaming, tool use, and cost-saving prompt caching.

About

The claude-api skill provides a production-ready framework for developers to implement Anthropic's Messages API efficiently and securely. It streamlines complex implementation tasks such as setting up prompt caching for 90% cost reduction, handling 429 rate limit errors with exponential backoff, and configuring advanced features like tool use (function calling) and vision capabilities. Designed for high-performance environments, it includes validated templates for Node.js, Cloudflare Workers, and Next.js, ensuring your AI integrations are performant, cost-effective, and resilient to API fluctuations.

Key Features

Robust Error Handling including exponential backoff for 429 and 529 API errors.
Production-ready templates for Streaming, Tool Use, Vision, and Extended Thinking.
Cross-platform support for Node.js, Cloudflare Workers, and Next.js environments.
Pinnable model configurations for Claude 3.5, 3.7, and 4.5 Sonnet versions.
Advanced Prompt Caching patterns for up to 90% cost reduction on large contexts.
