Hailo

Hailo Technologies Ltd. is an Israeli fabless semiconductor company, headquartered in Tel Aviv with offices in the United States, Germany, Japan, Taiwan, China and South Korea, that designs AI inference accelerators (the Hailo-8, Hailo-8L and Hailo-10 families) and AI vision processors (the Hailo-15 SoC family) for edge devices. Its developer surface is not a hosted web API: it is an on-device software stack published largely on GitHub under the hailo-ai organization — HailoRT, a C/C++/Python runtime library plus the hailortcli command line tool and a PCIe kernel driver; the Hailo Model Zoo of pre-compiled HEF models; TAPPAS and hailo-apps application pipelines; and the Hailo Media Library and Hailo Imaging stacks for the Hailo-15 vision processor. The machine-readable contracts Hailo publishes are Protocol Buffers — a 33-RPC gRPC MediaLibraryService, the HailoRT hRPC and GenAI message schemes, the HEF model-file format, and a WebSocket/ZMQ analytics metadata scheme. Hailo also publishes a first-party Agent Skills package (hailo15-agentic-coding) of twelve skills that drive board connection, pipeline editing, model swapping, cross-compilation and deployment on the Hailo-15 SBC.

Hailo is listed with 2 APIs on the APIs.io network. Tagged areas include Artificial Intelligence, Machine Learning, Semiconductors, Edge Computing, and Computer Vision.

Hailo’s developer surface includes documentation, API reference, support, engineering blog, CLI, changelog, authentication, and 17 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 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/hailo: 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
ONVIF Video Analytics (video surveillance, edge cameras, computer vision)	undeclared	-	-	1
Semiconductor Consortia (RISC-V, OCP hardware, CHIPS awards)	undeclared	-	-	1
Buf Schema Registry (public Protocol Buffers modules, gRPC / ConnectRPC schema publishers)	undeclared	-	-	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 2

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.

gRPC

tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified

    lifecycle (Initialize, StartPipeline, StopPipeline, Shutdown), profile and ISP configuration, frontend output streams,
    thermal throttling state, and zero-copy buffer exchange with the encoder. A companion Protocol Buffers scheme describes
    the analytics metadata frames (detections, landmarks, classifications, tracking ids) the analytics API emits over WebSocket
    and ZMQ. The service runs on the board, so there is no public internet base URL.

    inventing one would be a fabrication.
