Krisp

Krisp is a Voice AI platform whose real-time speech-enhancement models run on over 200 million devices, licensed by Discord, Twilio, and VMware among others. Beyond its consumer AI Note Taker, Krisp ships a developer surface: the AI Voice SDK family (VIVA for voice AI agents — voice isolation, turn prediction, interruption prediction, VAD; and RTC for human-to-human calls — accent conversion, bidirectional noise cancellation, background voice cancellation) across Windows, macOS, Linux, Web (JS/WASM), iOS, and Android with C++, Python, Node.js, Go, Rust, and JavaScript bindings, plus framework integrations for LiveKit, WebRTC, and Pipecat. Krisp also runs a self-serve Voice Translation API — a streaming WebSocket speech-to-speech translation service covering 61 languages behind a REST session-token mint — and a programmatic SDK and model download REST API for CI/CD pipelines.

Krisp publishes 2 API contracts indexed on the APIs.io network: SDK Distribution API and Voice Translation API. Tagged areas include Company, Artificial Intelligence, Voice AI, Speech, and Audio.

The Krisp catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

Krisp’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 32 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the AI & Biometrics 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):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Pagination +5 pts — share of collection GETs (an array, or one wrapped in data/items/results ...) that declare a page/limit/offset/cursor parameter, a Link header or a next/cursor field; na with no collection GETs

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.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Zoom App Marketplace and Partner Ecosystem (builders and partners on Zoom)	builds-on	42.1	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
