**APIs profiled:** 1

Stilta is an agentic AI platform for high-stakes patent and intellectual property work, backed by a16z, NVIDIA, and Y Combinator (W26). Its agents automate evidence gathering and analysis across 180M+ patents, scientific literature, and archived web content to deliver source-cited invalidity analysis, infringement analysis, and freedom-to-operate assessments for in-house IP teams and intellectual property law firms. The platform markets a defensible first answer in roughly seventeen minutes, fully autonomous, with citations pulled from original documents. Stilta exposes a first-party backend API (api.stilta.com, "Patrona Patent Search Platform API") and a PropelAuth-based OpenID Connect identity surface at auth.stilta.com, but does not publish public developer documentation, an OpenAPI specification, or SDKs at this time. This profile was surfaced as an a16z / Y Combinator portfolio company and enriched from Stilta's public web surface.
