8 categories from the Store API, a fake e-commerce API. The eight product categories.

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.

Fields

Field	Type	Notes
`id`read-only	int	Assigned by the server. Seed records keep their ids across restarts; records you create continue after the seed.
`created_at`read-only	datetime	When the record was created (ISO 8601, UTC).
`updated_at`read-only	datetime	When the record last changed.
`name`required	string
`slug`required	string
`description`	text
`product_count`read-only	int	Seed products in the category.

Relations: products → the products whose category_id is this category. Use ?expand=products to embed them, or the nested routes.

Endpoints

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

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

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

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

DELETE/v1/store/categories/{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/categories/{id}/productsIts products, as a page with all the list options.

GraphQL

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

{
  categories(limit: 3, sort: "-id") {
    total
    data {
      id name slug description
      products(limit: 2) { id }
    }
  }
}

Run it

curl https://api.sondahub.com/v1/store/graphql -H "Content-Type: application/json" -d '{"query": "{ categories(limit: 3, sort: \"-id\") { total data { id name slug description products(limit: 2) { id } } } }"}'

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/categories.
