Build with KYE Protocol™

The numbers (today, on main)

What you’ll build with

Five-line PDP example

import { KyeClient } from "@kye-protocol/sdk";
const kye = new KyeClient({ apiKey: process.env.KYE_API_KEY });

const decision = await kye.decisions.create({
  actor:    "kye:agent:acme.kyc_triage_001",
  principal:"kye:user:acme.compliance_lead",
  capability:"kyc.verify",
  action:   "kyc.verify",
  context:  { customer_id: "cust_001", region: "EU" }
});

console.log(decision.decision, decision.reason_code);
// → "allow" "policy_allow_default"

Or the new KYE Agent Dev Kit™ one-line wrapper

import { withKye } from "@kye/agent-dev-kit";

export const handler = withKye(
  async (ctx, input) => {
    await ctx.runtime.emitToolCall({ tool: "greet" });
    return { greeting: `hello ${'$'}{input.name}` };
  },
  {
    tenant_id: "kye:tenant:my-tenant",
    actor:     "kye:agent:my-tenant:hello",
    principal: "kye:org:my-tenant",
    gateway:   "https://gateway.kyeprotocol.com",
  },
);
// Every invocation auto-emits the §0.3 governance event family.
// Regulators can replay any decision with the publisher’s JWKS alone.

What’s open vs. paid

Every decision the protocol stands for produces signed evidence that a regulator, court, auditor, or dispute panel can replay offline using only the publisher’s JWKS. No vendor cooperation required.
