{"id":"graphql-cost","title":"GraphQL depth and static complexity score","description":"Parses a GraphQL document (query, mutation or subscription) per the June 2018 spec and returns depth, field count, alias count, fragment list, cycle detection and a static complexity score. Complexity uses the common 'Σ field-score × list-multiplier' model: a listFields config maps parent-type + field-name to either a constant multiplier or a field argument name to read (e.g. 'first', 'limit'), with a defaultListMultiplier fallback. Returns fail when depth or complexity exceed configured limits, or the query is syntactically invalid or has a fragment cycle. No schema is required; this is a pre-schema gate for rate limiting.","roi":"A depth-50 nested query from a public token is the oldest GraphQL outage.
