# List lookup keys

> Every key you hold — or, named by up to ten keys, every product a page sells resolved in one read.

Without a filter: every key you hold, ordered by the key, each naming its configuration and version. A removed key is not listed. The list does not page.

With `lookup_key` repeated up to ten times: exactly the named keys you hold, each with `version`. This is the read to make when a page is priced — one request answers every product on it. A named key you do not hold is simply absent.

## Path parameters

<ParamField path="tenant_id" type="string" required>
  The Tenancy asking.
</ParamField>

## Query parameters

<ParamField query="lookup_key" type="string">
  A key to resolve. Repeat the parameter for each, up to ten: `?lookup_key=meses&lookup_key=quincenas`. More than ten is <Badge color="orange">400</Badge> `invalid_query`, the bound in `details`.
</ParamField>

## Response

<ResponseField name="lookup_keys" type="object[]" required>
  The keys, each as [reading it](/api-reference/product-lookup-keys/read) answers — with `version` when the request named keys, without it otherwise.
</ResponseField>
