API Detective

Instantly find which API (REST/GraphQL) contains any value, property, or business term.

Stop digging through the Network tab. API Detective tells you exactly which API contains the value, field, or business term you're looking for — in seconds. Type anything: a property name (customerId), a value (an IMEI, an order ID), or a business term. API Detective deep-searches every request and response — URLs, JSON bodies, GraphQL queries and variables — and shows you exactly where each match lives with a JSON-path breadcrumb: Response └── phoneItems └── 0 └── specifiedPhones └── 14 └── originalName = Number of Phones FEATURES • Deep value & property search across REST and GraphQL traffic • JSON-path breadcrumbs pinpoint every match — no more manual hunting • Live capture in a DevTools panel, or import a .har file • Pretty-JSON viewer with the match highlighted • GraphQL calls named by operation (GetCustomer), not "POST /graphql" • One-click copy of the exact Network-tab name to jump back to a request • Light and dark themes PRIVACY Everything runs locally in your browser. API Detective does not collect, transmit, or store your traffic anywhere. No account, no servers. Open DevTools (F12) → the "API Detective" panel → start searching.
