Ventuals

Ventuals was a Paradigm-incubated trading venue for perpetual futures on frontier technology — pre-IPO private companies (SpaceX, OpenAI, Anthropic), thematic stock indices, and commodities — built on Hyperliquid's HIP-3 builder-deployed perps standard, margined and settled in USDH with up to 20x leverage. Ventuals published no first-party API; its vntl-prefixed markets were accessed programmatically through the Hyperliquid API (dex "vntl"). The platform announced its sunset on June 15, 2026, settling all markets that week and winding down vHYPE, with a sunset page maintained through at least September 15, 2026.

Ventuals is profiled on the APIs.io network. Tagged areas include Company, Crypto Defi, Perpetual Futures, Pre-IPO, and Derivatives.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ventuals: open an issue to ask a question, or submit a pull request to add artifacts.
