About claude-api

C

claude-api

Claude API integration for building LLM-powered applications across Python

claude-api is an agent skill from Anthropic's skills repository, listed on skills.sh. It guides building LLM-powered applications with Claude through the Anthropic SDKs, covering Python, TypeScript, Java, Go, Ruby, C# and PHP. It chooses the right surface for the need, detects the project's language and reads the matching documentation. The listing says the default model is Claude Opus 4.6, with adaptive thinking and streaming, and the single messages endpoint supports tool use, structured outputs, batches and file uploads. The skill has strict rules: it uses the official SDK whenever one exists, uses raw HTTP only when asked or when there is no SDK, does not mix the two, and does not guess SDK function names but checks documented sources first. It refuses to write Anthropic SDK code into a file that is built on a non-Anthropic provider, and asks the user first. A skill is a SKILL.md file of instructions that an AI agent loads when a task calls for it. It is free and open source, and the skills.sh listing shows all three security audits passing.
