Common Questions
Public and Pro keys are self-serve — create one for free in the developer portal in minutes, no sales call needed. Public is free forever; Pro is a paid self-serve upgrade. The Enterprise API is separate and contact-gated: request an enterprise evaluation key to test the data.
Both use the same self-serve API. Public is a free key — rate-limited, with 60-minute and daily resolutions. Pro is real-time over REST and WebSocket, adds intraday resolutions, full history and the complete index family (realized vol, prime rate, IV).
Yes — that is the Enterprise API: settlement-grade licensing, direct SLAs, on-prem or co-located distribution and custom indices. Request an enterprise evaluation key and a solutions engineer will scope terms.
Pro is billed monthly with no commitment, self-serve from the portal. Enterprise contracts are custom — annual by default, with usage-based components available.
Yes — create a free API key and start a 14-day Pro trial from the developer portal. No sales call required.
Need Custom Indices, Licensing or Co-Located Distribution?
Enterprise teams use Volmex indices as settlement references for ETFs, structured products and on-chain derivatives, over a separate settlement-grade API. Request an enterprise evaluation key and a solutions engineer will scope the integration with you.
