    ## Brand Context Intelligence Platform


    VoyantIO provides AI-powered brand context management for GTM teams.


    ### Core Capabilities


    - **Context Streams** - Centralized brand knowledge that any AI tool can use

    - **Telemetry** - Visitor tracking with IP geolocation and company enrichment

    - **Signals** - Social listening across 10+ platforms: GitHub, Reddit, HackerNews, LinkedIn, Twitter/X, Discord, ProductHunt, YouTube, G2, Slack, and government sources

    - **Target Graph** - Account and contact intelligence with engagement tracking

    - **RAG** - Retrieval-augmented content generation with brand awareness


    ### Authentication


    Most endpoints require a Bearer token from Clerk authentication.

    Public endpoints (telemetry ingestion, well-known files) are clearly marked.


    ### Rate Limits


    - Telemetry ingestion: 100 req/min per IP

    - API endpoints: 1000 req/min per org
