API List

A collective list of APIs. Build something.

Enterprise LLM gateway and self-hosted AI platform: Chat, Code, and Agent workspaces on top of centralized access control, budgets, and usage visibility. An alternative to running LiteLLM plus custom auth, UI, and admin tooling.

SecondStack gives an entire organization access to AI without handing its data to third-party clouds.

The platform ships three end-user workspaces — Chat for everyday work, Code for engineering teams, and Agent for automation — running on top of an enterprise LLM gateway that connects to the model providers you choose (OpenAI, Anthropic, Google, and others). Platform and security teams manage everything centrally: who can use which models, what each team spends, and where data lives — inside your own infrastructure.

Because SecondStack is self-hosted, prompts, files, and knowledge bases never leave your environment. For teams that prefer not to operate it themselves, a managed deployment run by the SecondStack team is also available.

Pricing is not per-seat, so rolling AI out to the whole company does not multiply the bill. Deployment and operations are backed by an ISO 27001-certified implementation partner.
