Search academic standards

Searches for StandardsFrameworkItems using either semantic search or exact statement code match across all standards frameworks.

This endpoint supports two mutually exclusive search modes:

Semantic search (query): Full-text semantic search against the standard’s description. Results are ranked by relevance and include a score reflecting vector similarity.
Code search (statementCode): Exact statement code match (e.g., “3.NF.A.1”). Case-insensitive, no partial matching. All results carry a score of 1.0.

Exactly one of query or statementCode must be provided. Providing both or neither returns a 400 error.

Results can be narrowed further using the optional filters and support cursor-based pagination.

Use this endpoint when you need to:

Find academic standards relevant to a concept or learning goal (semantic search)
Look up an academic standard by its exact statement code
Find all standards frameworks that include a specific statement code
Filter search results by grade level, subject, or statement type

Note: Not all academic standards have statement codes - some organizational groupings may have null codes and won’t appear in code search results.
