Claude API at a tenth of the price

Why developers use KLINCH for Claude

• About 10x cheaper. You pay only for tokens you use, with no monthly plan.
• Drop in replacement. The Anthropic Messages API and the OpenAI Chat Completions API both work, so existing code keeps running.
• One balance for every model. GPT, Gemini, DeepSeek and Grok run on the same key.
• Works with your tools. Claude Code, Cursor, Cline, Aider, Codex and any OpenAI or Anthropic SDK.

Use it with the Anthropic SDK

Only the base URL and the key change. Model names match the list in the cabinet, for example claude-sonnet-5-5.

import anthropic

client = anthropic.Anthropic(base_url="https://api.klinch.cloud", api_key="kl_live_…")
msg = client.messages.create(
    model="claude-sonnet-5-5", max_tokens=1024,
    messages=[{"role": "user", "content": "Hello"}],
)
print(msg.content[0].text)

Which Claude model to pick

• Haiku: fast replies, classification, drafts. The cheapest.
• Sonnet: the everyday model for code and writing, the best value.
• Opus and Fable: hard architecture work, long agent runs, deep analysis.
