Pre-launch API. The concepts described here are settled, but the API shape is not: request and response fields, parameters and defaults can still change. Build against it, and talk to your Luigi's Box contact before you put an integration into production.

Authorizations
Section titled “Authorizations ”Parameters
Section titled “ Parameters ”Query Parameters
Section titled “Query Parameters ”Channel identifier (serving destination).
Channel identifier (serving destination).
Surface identifier, lbs_
Surface identifier, lbs_
Header Parameters
Section titled “Header Parameters ”Stable per-browser visitor identifier, generated client-side and persisted (e.g. a UUID in localStorage or a first-party cookie). Send it whether or not personalization is on: it is what links a request to a visitor’s history and to the analytics events reporting it. Keep it stable across page loads, sessions and token refreshes; never generate it server-side, or every visitor collapses into one.

Originating client’s User-Agent. Optional; used to derive the platform (ios, android, web) the result set is attributed to. A backend caller should forward the end user’s value rather than its own.

Request Body required
Section titled “Request Body required ”JSON body accepted by the recommender endpoint.
object
Seed object ids the recommendations are based on.
Include a diagnostic debug payload in the response.
Deduplication strategies to apply to the recommended objects.
A group node: exactly one of $and, $or, $not.
object
Nodes that must all match.
A condition node: field names mapped to operator objects; sibling fields combine as AND.
object
Operators applied to one field. Several operators in one object combine as AND.
object
A condition node: field names mapped to operator objects; sibling fields combine as AND.
object
Operators applied to one field. Several operators in one object combine as AND.
object
Nodes of which at least one must match.

object
Operators applied to one field. Several operators in one object combine as AND.
object

object
Operators applied to one field. Several operators in one object combine as AND.
object
Whether to personalize results for the given user.
Object fields to return; empty for the surface default, or [’*’] for all fields.
Number of recommended objects to return.
Catalog object type to retrieve, for example ‘product’.
Stable identifier of the end user, used for personalization.
Responses
Section titled “ Responses ”Successful Response
Response of the recommender endpoint.
object
Ranked list of recommended result hits — only objects this channel can serve.
Single result item returned by discover endpoints.
Flat structure — all catalog fields are top-level keys.
@id and @type are always present; every other key is a catalog field.
object
Unique identity of the hit.
Type of the hit (e.g. ‘product’).
Number of matching results, counting only the objects this channel can serve.
Example generated
{ "debug": {}, "hits": [ { "@id": "example", "@type": "example" } ], "total": 1}Malformed request
Canonical error body — every non-2xx response uses this shape.
object
Machine-readable error context; empty object when there is nothing to add.
object
One field-level reason a request was rejected.
object
Path to the offending value from the request root, e.g. ["body", "filters", 0, "operator"].
What is wrong with the value at loc.
Stable machine code for the problem, e.g. missing or string_too_short.
Human-readable, actionable error message.
Example generated
