Staircase

Staircase, Inc. operates the Elephant Protocol (elephant.xyz), a decentralized property-data network that aggregates and cryptographically verifies fragmented county property and address records into trusted, agent-consumable data. It publishes 500,000+ enriched property data points and an unusually agent-native developer surface: a Model Context Protocol (MCP) server (@elephant-xyz/mcp, both stdio and hosted), an Elephant CLI (@elephant-xyz/cli) for oracle data transformation and on-chain proof submission to Polygon, a fact-sheet generator, and a library of 14 published Agent Skills for county-data ingestion. An Enterprise API is offered to organizations at scale. Backed by Bessemer Venture Partners; originally a mortgage-technology API company, now focused on real estate data infrastructure.

Staircase is profiled on the APIs.io network. Tagged areas include Company, Fintech, Real Estate, Property Data, and Data.

Staircase’s developer surface includes documentation, engineering blog, support, CLI, and 13 more developer resources.
