What is Zatanna?

Zatanna converts legacy software workflows that lack APIs into stable, callable endpoints for AI agents. Part of YC W2026, it was founded by Rithvik Vanga (CEO, ex-Coinbase), Alex Blackwell (CTO, reverse engineering expert), and Tarun Vedula (COO). Rather than using brittle browser automation or RPA-style screen scraping, Zatanna observes a human executing a workflow once, reconstructs the underlying HTTP request sequence (including session management, cookies, TLS fingerprinting, and re-authentication), and hosts it as a clean REST API.

The platform targets industries with entrenched legacy software — ERPs, PMS/POS systems, insurance portals, and marketplaces where no API exists. AI agents call a single endpoint while Zatanna handles the fragile infrastructure underneath. The company claims to already support millions of requests with customers including Pikkit, Fleetline, CrowdVolt, and PartBay.

This approach is fundamentally faster, cheaper, and more reliable than traditional RPA because it operates at the HTTP layer rather than the browser DOM layer, eliminating the brittleness of screen scraping while maintaining the no-code simplicity of showing a workflow once to get a production API.

Using Zatanna with Respan

Zatanna creates APIs from legacy software for AI agents, while Respan monitors the LLM calls those agents make. Together they enable agents to access legacy systems while maintaining full observability.
