Koo was an Indian microblogging and social networking platform built by Bombinate Technologies, positioned as a multilingual, India-first alternative to Twitter/X with support for Hindi, Kannada, Tamil, Telugu, Marathi and other regional languages. Backed by Accel and Tiger Global, it grew during the 2021 Indian social-media policy disputes before ceasing operations in 2024 after funding and acquisition talks fell through. Koo never published a public developer portal, API documentation, or client SDKs, and its domain no longer serves a site — this profile is retained as a verified-defunct historical record rather than an active API provider.
Koo is profiled on the APIs.io network. Tagged areas include Company, Social, Social Network, Microblogging, and India.
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/.
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/koo: open an issue to ask a question, or submit a pull request to add artifacts.

findings:
- https://www.kooapp.com/ and https://kooapp.com/ return HTTP 404 serving a Wix "ConnectYourDomain Error" placeholder —
the domain resolves to Wix nameservers (ns2/ns3.wixdns.net) but no site is connected.
- No developer, docs, or api subdomain resolves (developers./docs./api.kooapp.com all fail to connect), and none appears
anywhere in the Wayback Web Archive index across ~50,000 archived kooapp.com URLs — only www.kooapp.com and the apex were
ever captured.
- All five probed /.well-known/ paths return 404 (see well-known/koo-well-known.yml).
- GitHub org koo-app exists but has 0 public repositories. Parent-company org bombinatetech has 16 public repositories,
all forks of general-purpose open source libraries (tus/tusd resumable upload, Elixir tooling, mobile UI components) —
no Koo API, SDK, or client library.
- No packages matching Koo on npm; no first-party SDK found on any package registry.
- Last Wayback capture of a live Koo site is dated 2024-10-30.
conclusion: No API, no developer portal, no SDKs, no event surface. No API artifacts were generated, as fabricating them
would misrepresent a company that never had a public API program.
