Fake carts API

200 carts from the Store API, a fake e-commerce API. Open shopping carts; items are a nested array, so a cart is one document.

Reads with filters, sorting, search and relations; writes that answer like a real server and stay in your session token. Same ids on every build. Free, no key, CORS open.

`updated_at`read-only	datetime	When the record last changed.
`customer_id`	int → customers

`items`	json { product_id, sku, name, quantity, unit_price }[]
`item_count`	int	min 0

Endpoints

GET/v1/store/cartsA page, with every filter, sort, search, field and expand option.

POST/v1/store/cartsCreate one: 201 with the record, its id, a Location header and the session token that keeps it; 422 names each field that is wrong.

GET/v1/store/carts/{id}One record, with an ETag; If-None-Match earns a 304.

PATCH/v1/store/carts/{id}Change the fields you send.

PUT/v1/store/carts/{id}Replace the record; required fields must all be there.

DELETE/v1/store/carts/{id}Answers 200 with what was removed (a real server’s 204 lives at /v1/utils/status/204); gone for the session.

GET/v1/store/carts/{id}/customerThe customer this record points at.

GraphQL

The same carts as the carts query on https://api.sondahub.com/v1/store/graphql, and one cart as cart(id: 1). Introspection is on. More on the GraphQL API.

{
  carts(limit: 3, sort: "-id", filter: { status: open }) {
    total
    data {
      id customer_id session_id status
      customer { name }
    }
  }
}

Run it

curl https://api.sondahub.com/v1/store/graphql -H "Content-Type: application/json" -d '{"query": "{ carts(limit: 3, sort: \"-id\", filter: { status: open }) { total data { id customer_id session_id status customer { name } } } }"}'

From an AI agent (MCP)

The MCP server reaches the same rows with list_records, get_record, create_record, update_record and delete_record, and as the resource sondahub://store/carts.
