Developer tools
Official clients for Drex and Perception. Each one covers both products with one API key.
Each client calls https://console.nace.ai and covers both products: Drex's decision model and Perception's document tools, uploads, jobs and saved schemas. They all take the same nace_sk_ key, read from NACE_API_KEY or saved by nace login. Create one as shown in Authentication.

CLI
