Sandbox

# Build an authorize call in your browser.

Pick the actor, principal, capability and scope. The page builds the request, shows the JSON, prints a curl you can copy, and displays a deterministic stub **Decision Map™** response in the same shape the reference Gateway returns.

[Apply for pilot →](https://kyeprotocol.com/pilot-apply/) [Read the docs](https://kyeprotocol.com/docs/)

_This sandbox runs entirely in your browser. The response is a deterministic stub — for live authorize calls, run the reference Gateway locally (`npx wrangler dev` (in `internal`)) and replace the URL._

## Authorize playground.

Every claim here is backed by the open KYE Protocol™ contracts and verifiable end-to-end from the publisher's JWKS — you check it yourself, you don't take our word for it.

## Contact

Your request goes to the KYE Protocol™ team, and a receipt with a reference number is emailed to you.

## When you're ready to go live.

You see the timing rules that bind every governed decision — admission, replay window, retention floor — all signed and replayable offline.

1. **Run the reference Gateway.** `npx wrangler dev` (in `internal`). POST to `http://localhost:4000/v1/runtime/authorize` with the same payload above — you'll get a real signed Decision Map™ back.
2. **Run the conformance pack.** 133 black-box scenarios, byte-for-byte the same as the reference Gateway. See the [conformance-run playbook](https://kyeprotocol.com/playbooks/conformance-run/) for clone + run + sign + register.
3. **Wire it into your stack.** See the [developer portal](https://kyeprotocol.com/developers/) for SDK quickstarts (TypeScript / Python / Go) and webhook verification.

## From free tool to a governed pilot

The sandbox is free and needs no signup. When you are ready to govern real actions the path is short and the value is concrete: a free trial in your browser today, a working account this week, a signed pilot in 4–8 weeks.
