Nex

Nex is the workflow execution and context layer for AI-native business operations — where AI workflows become reliable business software. It builds a unified context graph from a company's connected tools (email, calendar, Slack, and CRMs like HubSpot, Salesforce, and Attio) plus ingested unstructured context, then grounds AI agents in that shared organizational memory. The Nex Developer API is a REST API over the context graph: define object types and attributes, create records and typed relationships, group them into lists, attach tasks and notes, read record timelines, ingest context, ask grounded natural-language questions, stream AI-derived insights over SSE, run full-text search, and trigger compounding intelligence jobs. Authentication is via scoped API keys, and organizational context is also exposed to agents through a first-party Model Context Protocol (MCP) server shipped as the nex CLI.

Nex publishes 16 APIs on the APIs.io network, including AI Lists API, Compounding API, Context API, and 13 more. Tagged areas include Company, AI Agents, Knowledge Graph, Context, and Memory.

Nex’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, pricing, signup flow, and 19 more developer resources.
