Overview
FedEx Payload Tools is a developer-focused suite for validating, generating, and testing FedEx API payloads. It combines a deterministic schema registry, AI-powered repair, and direct FedEx sandbox integration — so you can go from raw JSON to sandbox-accepted payload in seconds.
Examiner
Paste any FedEx JSON payload. Get instant validation, AI repair, and a fixed version you can use immediately.
Builder
Describe your shipment in plain English. The AI generates a complete, valid payload ready for sandbox or production.
Sandbox
Run your payload directly against the FedEx sandbox API with automatic retry and repair until it succeeds or exhausts attempts.
Admin
Full visibility into every analysis session, engine run, and FedEx error — with JSONL export for offline debugging in Cursor.
