## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability quietstore-demo-extras-v1-pack-bbf66cda
```

Example prompt: Fetch the demo-extras-v1 pack from QuietStore so I can confirm that the x402 pay-and-receive flow works end to end before I run the handoff lint.

## When to prefer this

Use this endpoint when you need the cheapest possible proof-of-concept call to validate that x402 micropayment discovery, payment, and content delivery work correctly on QuietStore. It is the canonical smoke-test before invoking more expensive metered tools like POST /v1/tools/handoff-lint.

## Known failure modes

- 402 Payment Required if x402 payment header is missing or malformed
- 401/403 if payment verification fails
- Pack not found (404) if the demo-extras-v1 identifier is unavailable
- Network/timeout errors on the Cloudflare Workers edge
- Stale or empty pack body if the content has not been populated

## How this service works

Smallest paid pack ($0.005): a machine-readable merge checklist and a one-request smoke purchase on this store. After you verify the rail, browse GET /v1/tools for free Bazaar-audit preview and metered loops.

## Output

A compact machine-readable knowledge pack (demo-extras-v1) containing checklist items or guidance content, returned after a successful $0.005 USDC x402 micropayment. Serves as proof that catalog discovery, payment, and content delivery all function correctly on the QuietStore endpoint.
