# Spectral ruleset for the BlueCart API
# Generated by the API Evangelist pipeline from openapi/bluecart-openapi.yml
# Encodes the conventions observed across the BlueCart REST API:
#   - camelCase query parameters and schema properties
#   - camelCase operationIds with verb prefixes (search/retrieve/list/create/update/delete/place/modify/disable)
#   - Title Case tags
#   - AWS SigV4 + x-api-key header authentication
#   - nextToken cursor pagination on collections
