Response Surface Analyzer
Compute API response size, field count, nesting depth, and repeated patterns to highlight bloat and excessive data exposure risks. Free by Graph Tools.
Use this free response surface analyzer to measure the attack surface and bloat of your API payloads. Paste a JSON response and get metrics for total size, unique field count, maximum nesting depth, repeated key patterns, and an exposure risk indicator. High field counts and deep nesting can signal over-fetching and excessive data exposure. Useful for security reviewers, backend performance engineers, and API design teams.
