**APIs profiled:** 1

Zatanna is a Y Combinator (W2026) startup based in San Francisco that creates APIs for software that doesn't have any. It reverse-engineers the back ends of web-based cloud and on-prem software — ERPs (SAP), PMS/POS systems, insurance portals, and marketplaces — by observing real workflows, reconstructing the underlying request sequences, and hosting them as clean, callable APIs. Rather than relying on slow browser automation or computer-use agents, Zatanna gives AI agents faster, cheaper, and more reliable integrations, with a reliability layer that handles session management, authentication, and change detection. The agent-facing surface is a hosted, OAuth-protected Model Context Protocol (MCP) server at api.zatanna.ai.
