Search 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 ascorereflecting vector similarity. - Code search (
statementCode): Exact statement code match (e.g., “3.NF.A.1”). Case-insensitive, no partial matching. All results carry ascoreof 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.
