API

Build on the Nexus platform. Access our consensus engine, research engine, document intelligence, and memory systems through a clean, well-documented API.

Endpoints

What you can build

Every Nexus capability, accessible via API. Build AI features into your own products without building the infrastructure from scratch.

Consensus API

Multi-model consensus

Send a question, get responses from multiple models, and receive a synthesized answer with confidence scores. The same engine that powers Quorum, available for your apps.

Research API

Deep research

Trigger multi-model deep research on any topic. Get comprehensive, cited reports with cross-validated findings.

Document API

Document processing

Upload documents for extraction, validation, and querying. Handles complex formats with staged processing pipelines.

Memory API

Knowledge retrieval

Store and retrieve knowledge from your data. Embeddings, knowledge graphs, and intelligent retrieval — without building the infrastructure yourself.

Preview

Clean, predictable interface

consensus.js
// Query multiple models and synthesize
const response = await nexus.consensus({
  question: "What are the key risks in this contract?",
  models: ["claude-opus", "gpt-5", "gemini-pro"],
  context: contractDocument,
});

// Synthesized answer with confidence
console.log(response.synthesis);
console.log(response.confidence); // 0.94
console.log(response.citations); // Per-model sources
