SDKs (TypeScript / Python / Go), CLI, Conformance Pack verifier, Shadow Mode SDK, schemas, OpenAPI, vocabulary — everything you need to integrate KYE Protocol™ locally. The operational engines (Authority Gap detection, Guard Recommendation, drift detection) ship as paid services on the hosted Cloud; the wire contract + verification surface are 100% open.
Banks, regulators and auditors need to verify what they're running. SDKs + schemas + wire-format are Apache-2.0 + CC-BY-4.0 so anyone can read, fork, certify. The paid Cloud runs the operational engines (Authority Gap detection, Guard Recommendation, drift) — the wire-format you bind to is yours forever.
Every package above has an open spec under private/specs/ mirrored to kye-protocol.github.io. Customer auditors can compile, conformance-test, and embed in their own change-control without a vendor NDA.
Each SDK has stakeholder labels (Developer · Integrator · Auditor · Regulator · Consultant · Contributor) — use the filter chips above. Coverage: TypeScript · Python · Go · CLI · Conformance verifier · Shadow Mode SDK · Schemas · OpenAPI · Webhook verifier · Vocabulary · ID format · Examples · Widget protocol.
Drop-in client for the KYE Gateway™. Auth-aware fetch with retries, evidence-pack download, decision replay.
Async + sync clients, typed models for every KYE schema, Conformance Pack verifier built in.
Zero-dep Go client. Webhook signature verification — implements the public vendor recipes; algorithm details not disclosed in this repository.
kye verify pack.bin · kye mint key · kye conformance run · kye replay <decision_id>.
Wrap an LLM payment agent in @kye-protocol/sdk; every submit_payment tool call routes through Authority + Purpose + Decision. Auditor downloads @kye/conformance-pack-verifier + replays a quarter of decisions offline.
Bank's CRO ships an Evidence Pack URL to the regulator. Regulator opens it in the KYE Evidence Viewer (open-source PWA) — no vendor login, full decision walk-through, OSCAL export.
A clinical-decision-support agent wraps its recommendation tool with kyeAgent.wrap(). Every recommendation carries a signed Decision Map; clinicians see the "why"; regulators get the integrity proof.
Vehicles run the Edge Arbiter with a Compiled Authority Bundle. Off-grid decisions log to the Offline Evidence Log; sync to the cloud Audit Pilot when connectivity returns.
Every package above accepts pull requests. The KYE Protocol™ specs live under private/specs/ in the mono-repo and are mirrored read-only to kye-protocol.github.io for offline reading.
How to contribute: open an issue on the package's GitHub repo · sign the CLA (one-click via GitHub OAuth) · submit a PR · CI runs the Conformance Pack against your change · two-maintainer review · merge.
Wire-format + SDKs + schemas + Conformance Pack verifier + Shadow Mode SDK are open source. Operational engines — Authority Gap detector, Guard Recommendation, drift detection, Audit Pilot orchestration — ship as paid services on the hosted Cloud. You can always self-host the verification side; you'd build the operational side yourself if you want zero hosted dependency.
Yes. Apache-2.0. Keep the LICENSE + NOTICE; the trademark rules (no using "KYE Protocol™" to label a non-conformant fork) are in trademarks.
No silent telemetry. The only data the SDK sends is what your code explicitly hands it (decision payloads, evidence packs). All clients support KYE_DRY_RUN=true to print-only.
Public via SECURITY.md in each repo. PGP key on /security.html. CVE disclosure within 7 days, fix within 30 unless coordinated extension. Severity follows CVSS v4.
