What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

list_products
List everything the demo store sells, with product ids and prices. Prices are in USD.
create_checkout
Start a checkout (an Agentic Commerce Protocol checkout session) with the products and quantities the user wants. Returns the session id, the cart and its total. If no api_key is given, a sandbox key is created and returned.
update_checkout
Replace the items in an open checkout (e.g. the user changed their mind). Any PayPal payment created for the old total is dropped.
get_checkout
Read the current cart, total, payment status and order of a checkout.
request_paypal_payment
Create a PayPal (sandbox) payment for the checkout's exact total. Returns approve_url, the PayPal link where the user approves the payment.
wait_for_payment_approval
Wait (up to 45s per call) until PayPal reports the user approved the payment. Returns still_waiting if the user has not approved yet.
complete_checkout
Place the order. With payment "paypal" the approved PayPal payment is captured first, and the order only goes through if PayPal confirms the money for the exact total. "mock" skips real payment (testing only).
cancel_checkout
Cancel an open checkout. Nothing is charged.

Common questions

Is Acp Sandbox safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 7 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

acp-sandbox

A hosted mock merchant implementing the Agentic Commerce Protocol (ACP) checkout API — for testing AI shopping-agent integrations end to end without real money, a real store, or real buyer data.

Live at https://acp-sandbox.flo-voice1.com — open it in a browser for the quickstart page, or hit the endpoints below directly.

Why

ACP defines how a shopping agent talks to a merchant to complete a purchase. Stripe's own test mode covers the *payment* side (test cards, test API keys), but there's no hosted "fake merchant" a third-party agent developer can point their code at to verify their ACP client logic actually works — creating a session, updating it, completing checkout, handling errors. This fills that gap.

v1 scope: checkout session lifecycle only (create / retrieve / update / complete / cancel), against a small static demo catalog. Payment is stubbed — any payment_data you send is accepted and the session is marked paid. OAuth delegated-authentication is not implemented in v1.

Quickstart

Get a test API key (no signup, no email verification — this is a sandbox):

curl -X POST https://acp-sandbox.flo-voice1.com/keys \

-H "Content-Type: application/json" \ -d '{"email":"you@example.com"}'

=> {"api_key":"acps_test_..."}

See what you can buy:

curl https://acp-sandbox.flo-voice1.com/catalog

Create a checkout session:

curl -X POST https://acp-sandbox.flo-voice1.com/checkout_sessions \

-H "Authorization: Bearer acps_test_..." \ -H "Content-Type: application/json" \ -d '{ "line_items": [{"id": "item_demo_headphones", "quantity": 1}], "currency": "usd", "buyer": {"email": "buyer@example.com"} }'

Complete it (any payment_data is accepted):

curl -X POST https://acp-sandbox.flo-voice1.com/checkout_sessions/{id}/complete \

-H "Authorization: Bearer acps_test_..." \ -H "Content-Type: application/json" \ -d '{"payment_data": {"handler_id": "test", "instrument": {"type": "card", "credential": {"type": "spt", "token": "tok_test"}}}}'

Inspect what your agent actually sent:

curl https://acp-sandbox.flo-voice1.com/logs -H "Authorization: Bearer acps_test_..."

Endpoints

Method	Path	Description
POST	`/keys`	Issue a test API key
GET	`/catalog`	List demo items you can reference in `line_items`
POST	`/checkout_sessions`	Create a session
GET	`/checkout_sessions/{id}`	Retrieve a session
POST	`/checkout_sessions/{id}`	Update a session (line items, buyer, fulfillment)
POST	`/checkout_sessions/{id}/complete`	Finalize checkout, creates an `order`
POST	`/checkout_sessions/{id}/cancel`	Cancel a session
GET	`/logs`	Last 50 requests made with your key

Responses follow the real ACP CheckoutSession / Order / Error schemas (2026-04-17 spec version) for the fields this sandbox supports. Fields outside v1 scope (discounts, fulfillment options, marketplace details, etc.) are simply omitted rather than faked.

Known v1 limitations

No real payment processing — complete always succeeds.
No OAuth delegate_authentication flow.
No fulfillment options (shipping/pickup) — sessions go straight to ready_for_payment.
Fixed demo catalog, not a real product feed.

Local development

npm install

npm run dev # tsx watch, http://localhost:3900

Uses Node's built-in node:sqlite (no native dependencies) for storage — data persists in ./data/acp-sandbox.db.
