# DEVELOPER SECTION

- [PX Architecture](/developer-section/px-architecture.md): Harnesses the power and security of decentralized storage networks while enabling end-users to access decentralize storage with ease.
- [PX Processes](/developer-section/px-processes.md)
- [PX Nodes](/developer-section/px-nodes.md): We are enhancing the robustness of the PX system with node decentralization.
- [PX API Reference](/developer-section/px-api-reference.md)
- [Auth](/developer-section/px-api-reference/auth.md): Auth authenticates the user and checks their PollinationX (PX) storage NFTs.
- [Upload](/developer-section/px-api-reference/upload.md): This API endpoint allows you to add a file to the decentralized storage.
- [Download](/developer-section/px-api-reference/download.md): This API allows you to download a file from the decentralized storage using its Content Identifier (CID)
- [PX SDK](/developer-section/px-sdk.md): Interact with the PollinationX APIs using the PollinationX SDK. With just a few lines of code, unlock the potential of PollinationX's infrastructure.
