This endpoint prepares expensive parts of a search (embeddings and AI-powered query expansions) asynchronously for a given query, returning a ULID search_id that can be used with the Search API to execute with lower latency.
  • Use with: Search API via the search_id body parameter

​
Authorization

​
X-Storefront-Access-Token
string
required
Token-based authentication header in the form of <YOUR_LAYERS_TOKEN>. Same requirements as the Search API.

​
Behavior

  • Returns HTTP 202 (Accepted) immediately with a search_id
  • Generates a ULID search_id that identifies the prepared search
  • Dispatches an asynchronous background job on a high-priority queue
  • Pre-computes embeddings and AI-powered query expansions
  • Prepared data is cached for up to 5 minutes; after TTL, Search falls back to normal processing

​
Response

​
202 Accepted

​
search_id
string
ULID identifier for the prepared search. Valid for 5 minutes.
