Anthropic
Anthropic is an AI safety company and the creator of the Claude family of large language models (Opus, Sonnet, Haiku, and the Fable/Mythos frontier line). The Claude Developer Platform exposes them through a single REST API at api.anthropic.com: the Messages API for text, vision, tool use, thinking, streaming and structured outputs; Message Batches for asynchronous work at half price; Files, Token Counting, Models, and experimental Prompt Tools; Managed Agents with sessions, environments, memory stores, vaults and scheduled deployments; a Skills API; and an Admin API for organizations, workspaces, members, invites and API keys. Authentication is x-api-key with a required anthropic-version date header and dated anthropic-beta opt-ins. Anthropic also authors two of the open standards the agent ecosystem runs on — the Model Context Protocol and the Agent Skills specification — and ships Claude Code, the terminal agentic coding tool, which doubles as a first-party stdio MCP server.
Anthropic publishes 29 API contracts indexed on the APIs.io network, including Messages API, Models API, Files API, and 26 more. Tagged areas include LLM, Anthropic, Artificial Intelligence, Claude, and Foundation Models.
The Anthropic catalog on APIs.io includes 2 event-driven AsyncAPI specifications, 1 JSON-LD context, and 4 Spectral governance rulesets.
Anthropic’s developer surface includes pricing, authentication, changelog, CLI, documentation, developer portal, support, and 139 more developer resources.

Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted .
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons ; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
prose — states compatibility; nothing published to check it against
