context for ai agents
Nia is an API and MCP layer that gives agents continuously updated context from libraries, research papers, and docs, so they don't hallucinate and you skip manual ingestion.
Benchmark
When LLMs encounter new APIs outside their training data, they guess. Nia provides ground truth.
For AI agents to be truly autonomous, they need reliable access to ground truth.
