Oklo
Oklo Inc. is a Santa Clara, California advanced fission company designing and deploying small modular reactors under the Aurora powerhouse brand. The Aurora is a liquid-metal (sodium) cooled, metal-fueled fast reactor derived from the Experimental Breeder Reactor-II (EBR-II) lineage, engineered as a "walk-away safe" passively cooled system that is self-stabilizing and self-controlling under loss-of-coolant and loss-of-shutdown conditions. Oklo's reactors are intended to run on recycled high-assay low-enriched uranium (HALEU) fuel, including legacy EBR-II material, with the company building out three vertically integrated fast-reactor businesses: clean power generation, advanced nuclear fuel fabrication and recycling, and medical radioisotope production. The first commercial Aurora is targeted for operation at Idaho National Laboratory (INL) in late 2027 to early 2028, supported by selection into the DOE Reactor Pilot Program and Fuel Line Pilot Projects, and the company has completed an NRC Phase 1 pre-application assessment. Oklo went public in May 2024 via merger with AltC Acquisition Corp (a SPAC co-founded by Sam Altman, who serves as chairman) and trades on the NYSE under ticker OKLO. Oklo's commercial posture is utility-scale and industrial — selling power, fuel cycle services, and isotopes to data center operators, defense customers, and industrial offtakers — and the company exposes no public developer API, SDK, or open source software.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Oklo the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Oklo scores 6.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Oklo
Each block below is one kind of artifact we hold for Oklo. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
