Onibi (Onibi inc.) is a video game studio founded in 2023 by Benjamin Devienne, with a distributed team in San Francisco, London and Bordeaux drawn from Blizzard, Riot, Ubisoft, EA and Rockstar. Its first title is Tomo: Endless Blue, a procedurally generated monster-taming voxel sandbox open world announced for Steam and funded through a Kickstarter campaign plus roughly $6.5M in seed capital from SeaX Ventures, Serena, Octopus Ventures and Pix Capital. Onibi is a consumer game studio, not an API provider: as of August 2026 the game is unreleased and the studio publishes no developer portal, API reference, SDK or machine-readable specification. The Steam page states an intent to keep the game moddable, but no modding API, tooling or documentation has been published yet, so there is nothing machine-readable to catalog.
Onibi is profiled on the APIs.io network. Tagged areas include Company, Video Games, Game Development, Game Studio, and Sandbox MMO.
Onibi’s developer surface includes engineering blog and 14 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) 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/.

Agent readiness — checks not met, largest first (exact, from this profile):
Machine-Readable Auth+10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
13 more unmet checks in the Agent Readiness table above.

detail: 'Onibi is a pre-release consumer game studio whose entire web presence is three static pages (Studio, Career, Contact)
plus a nine-language marketing site for the unreleased Tomo: Endless Blue — the Steam page promises the game will be moddable
but no modding API, SDK or developer documentation exists yet, and the only HTTP API on any Onibi host is /api/ on the
product site, which its own robots.txt disallows; onibi.gg answers HTTP 200 with the same 43KB homepage for /openapi.json
and every other probed path, so its 200s are soft-404s, while tomoendlessblue.com returns real 404s for all of them.'
