Introduction
Ontyx is a hosted MCP server that gives AI agents instant, structured answers to demographic and geospatial questions — no data engineering, no API plumbing.
It exposes a small, focused set of tools — demographic lookups (get_population, get_average_income) keyed by US zip code, plus a full location suite (geocoding, reverse geocoding, nearby search, satellite static maps) — so an agent can answer “what’s the average household income in 94110?” or “what’s around this address?” with a single tool call. The data layer, query routing, and credit accounting are handled for you.
Every account starts on the permanent free tier — no card, no time limit. See Pricing for tiers and monthly credit allotments.
Who is this for?
- Residential investors and brokers using Claude or another assistant to size up markets, listings, and rent potential
- Data agents and AI assistants that need quick demographic and location context during reasoning
- MCP clients such as Claude Desktop that want a drop-in geospatial provider
- Developers who prefer to call a direct HTTP API rather than the MCP protocol
Two access paths
MCP Server — The recommended path for AI agents. Once configured in your MCP client, Ontyx tools become available automatically. Your agent calls tools like get_population and get_average_income and receives structured JSON responses without writing any HTTP plumbing.
HTTP API — For developers who want fine-grained control, the same data is accessible over a conventional REST API. Both paths share the same authentication mechanism: a bearer token you generate from the dashboard.
