# Agent Quickstart

> Fetch the zero-to-delivered-order agent quickstart as plain markdown, served for agents to execute rather than read.

Returns the agent quickstart as plain markdown (`text/markdown`). **No authentication required.**

```bash theme={null}
curl https://api.zinc.com/sandbox/quickstart
```

Unlike this documentation site, the quickstart is written to be **executed** by an agent: every step is a concrete request, and every response points at the next step. It covers minting a key, placing a sandbox order, watching the lifecycle, rehearsing each failure mode, and going live — in about two minutes end to end.

<Tip>
  Point an agent at this URL when you want it to onboard itself. It's the same content as the [Agent Sandbox overview](/docs/v2/api-reference/sandbox/overview), shaped for a model's context window instead of a browser.
</Tip>

Zinc also serves a discovery file at [`/llms.txt`](https://api.zinc.com/llms.txt) that links the quickstart, the mint endpoint, and the OpenAPI spec.

    Zinc lets AI agents buy products from online retailers via a single API. Use
    POST /agent/orders to place an order — no Zinc account needed, payment is
    handled via MPP (HTTP 402 flow). Provide a product URL from a supported
    retailer, a shipping address, and max_price in cents. The API charges
    max_price + $1 API fee upfront and refunds the difference on completion. To
    find products first, the /agent/* data endpoints (search, products/search,
    products/offers, products/details) are MPP-paid at $0.01 per call;
    /agent/search returns orderable URLs to feed straight into /agent/orders.
    GET /retailers lists supported retailers for free (no payment or account).
    Authenticated equivalents (orders, products, managed-accounts) require a
    Bearer token (API key prefixed zn_). Docs: https://zinc.com/docs Supported
