Inception

Inception Labs builds diffusion-based large language models (dLLMs) branded Mercury. Unlike autoregressive models that emit tokens one at a time, Mercury generates many tokens in parallel through discrete diffusion, running 5-10x faster at roughly half the cost of comparable frontier models. The Inception API is OpenAI-compatible and exposes chat completions (Mercury 2, a reasoning dLLM with a 128K context, tool calling, and structured outputs), plus fill-in-the-middle and next-edit code completions (Mercury Edit 2) for IDE-style autocomplete. It ships official Python and TypeScript SDKs, a streaming/diffusion mode, and enterprise deployment via the Inception API, AWS Bedrock, and Azure AI Foundry. Backed by Amplify Partners.

Inception publishes 4 API contracts indexed on the APIs.io network, including Edit API, FIM API, Models API, and 1 more. Tagged areas include Company, Artificial Intelligence, LLM, Diffusion Models, and Code Completion.

Inception’s developer surface includes documentation, API reference, getting-started guide, authentication, engineering blog, support, pricing, and 27 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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/inception: open an issue to ask a question, or submit a pull request to add artifacts.

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
AI Model Routing	covered	44.1	-	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.
