nexos.ai

nexos.ai is an enterprise AI platform and OpenAI-compatible AI gateway that unifies many large language model providers behind a single API key and governed workspace. Its Gateway API exposes chat completions, responses, messages, embeddings, images, audio (speech, transcription, translation), batches, files, and storage, alongside management surfaces for models and fallbacks, teams, users, agents, assistants, companies, API keys, and per-company/team/user budget limits. Organizations get guardrails, observability, smart routing across models, agents (Agent Builder with human-in-the-loop approvals), and integrations with tools like Slack, Atlassian, GitHub, Google Workspace, and Microsoft 365. Founded by the team behind Nord Security and backed by Index Ventures and Creandum. This profile was enriched from the provider's public docs at docs.nexos.ai.

nexos.ai publishes 16 APIs on the APIs.io network, including Agent Management API, Assistant Management API, Audio API, and 13 more. Tagged areas include Company, Artificial Intelligence, LLM, AI Gateway, and Machine Learning.

nexos.ai’s developer surface includes documentation, API reference, getting-started guide, changelog, authentication, and 18 more developer resources.
