Anthropic

Anthropic is an AI safety company and creator of the Claude family of large language models (Opus, Sonnet, Haiku). The Claude API provides access to Claude models for text generation, vision, tool use, extended thinking, batch processing, and agentic workflows including managed agents, skills, memory, compaction, and computer use. Anthropic also publishes the open Model Context Protocol (MCP) for standardized AI tool integration and ships Claude Code, the terminal-based agentic coding tool.

Anthropic publishes 24 APIs on the APIs.io network, including Messages API, Models API, Message Batches API, and 21 more. Tagged areas include AI, Artificial Intelligence, Claude, Foundation Models, and Large Language Models.

The Anthropic catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 2 Spectral governance rulesets.

Anthropic’s developer surface includes authentication, changelog, CLI, documentation, developer portal, support, pricing, and 120 more developer resources.
