Voidpet

Voidpet is a creative games studio behind emotion-inspired games, stories, characters, and community — including Voidpet Dungeon, a turn-based roguelite RPG about befriending and battling emotion-inspired creatures, and Voidpet Garden, a mental-health companion game for collecting emotions and practicing self care. Beyond the games, Voidpet publishes a small, public, read-only Discovery API (OpenAPI 3.1) plus a hosted Model Context Protocol server and a packaged Agent Skill so agents can discover its public products, pages, and legal documents. The discovery surface exposes no accounts, game state, or authenticated actions — it is agent-facing metadata only.

Voidpet publishes 2 API contracts indexed on the APIs.io network: Discovery API and Health API. Tagged areas include Company, Games, Gaming, Mental Health, and Wellness.

The Voidpet catalog on APIs.io includes 1 Spectral governance ruleset.

Voidpet’s developer surface includes authentication, documentation, API reference, engineering blog, and 11 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health 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 does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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/.

Agent readiness — checks not met, largest first (exact, from this profile):

Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

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.
