Anthropic API

Claude models API by Anthropic

by anthropicApp Infrastructure

About

API access to Claude model family including Claude 3.5 Sonnet, Haiku, and Opus. Excels at coding, analysis, long-context tasks, and safety-critical applications.

Choose Anthropic API when…

  • You need long context windows (200k tokens)
  • Safety, reliability, and reasoning quality matter most
  • You're building agents that require deep code understanding
