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.
