Context Graph
The unified graph of entities, embeddings, and provenance edges — the substrate every recall reads from.

Quickstart and concepts
Install the SDK, ingest your first context, and fire your first Reflex in minutes. The full developer reference — API surface, CLI, SDKs, Reflex DSL — lives on the docs subdomain.
Quickstart
Four steps from cold install to your first reactive firing.
Install the SDK
Add the Contexta SDK to your TypeScript or Node service. A Python SDK ships alongside the TS one.
npm install @contexta/sdkInitialise the workspace
Scaffold a `contexta.config.ts` and pick a namespace. The CLI walks you through API key + region.
npx contexta initIngest your first context
Send a document, conversation, or event. Contexta extracts entities, embeds, and writes provenance edges.
import { Contexta } from '@contexta/sdk'; const ctx = new Contexta({ apiKey: process.env.CONTEXTA_API_KEY }); await ctx.ingest({ content: 'Alice prefers async standups and dark-mode dashboards.', userId: 'alice', tags: ['onboarding'], namespace: 'org_acme', });Fire your first Reflex
Declare a reactive trigger in CX. Reflexes fire with full provenance — what matched, why, and where it came from.
reflex: name: supplier_alert description: Alert when a supplier flips to bankrupt. trigger: cx: (c:company) -[:supplies]-> (us) AND (c @status: * -> "bankrupt") on: node(company:updated) action: url: https://hooks.example.com/supplier cooldown: 1h
Concepts
The vocabulary you need to read the rest of the docs. Each tile links to a glossary entry or feature leaf.
Context Packet
The structured, provenance-tracked output primitive returned by Recall and Reflex firings.
Read more →Reflex
A declarative reactive trigger expressed in CX. Compiles into Graphlets and StateWatches.
Read more →Synapta
The proprietary graph memory engine that owns the Context Graph and reactive pipeline.
Read more →Time Travel
Bi-temporal recall via `valid_at` + `learned_at`. Ask what was known on a given day.
Read more →Forget
Surgical, GDPR-shaped right-to-be-forgotten with provenance-preserving tombstones.
Read more →Examples
The three calls every Contexta integration ends up making.
Ingest a conversation
await ctx.ingest({
content,
userId: 'alice',
tags: ['support', 'thread:42'],
namespace: 'org_acme',
ttl: '90d',
});Recall with provenance
const result = await ctx.recall({
query: 'Where did Alice work?',
userId: 'alice',
asOf: '2025-03-15T00:00:00Z',
minConfidence: 0.85,
});
// returns what was known *at that time*, with full source attribution
console.log(result.citations);Register a reactive Reflex
await ctx.signals.create({
name: 'supplier_alert',
condition: { pattern: 'a company that supplies to us changes status' },
action: { type: 'webhook', webhookUrl: 'https://hooks.example.com/supplier' },
