PromptHub SDKs

PromptHub provides a full suite of open-source SDKs that allow developers, agents, and dApps to integrate seamlessly with the protocol stack—across prompt authoring, execution, visualization, governance, and tokenization. Each SDK is designed to be modular, developer-friendly, and production-ready.

1. 🤖 agent-sdk

A TypeScript/Node.js SDK designed for AI agents, LLM runtimes, and back-end integrations.

• Connects to PromptVault for prompt discovery and invocation

• Supports semantic routing through PromptRouter

• Automates PromptSig generation and verification

• Compatible with LangChain, AutoGPT, and other agent frameworks

• Enables DAG graph execution and chaining logic

• Implements MCP adapters for standardized model interactions, ensuring consistency across different LLM providers

2. 🖥️ ui-sdk

Frontend library (React/Vue) that provides hooks and utilities for:

• Displaying prompt metadata, licenses, token requirements

• Executing prompts via PromptCall from web interfaces

• Staking, rating, and reporting prompts

• Authenticated signature workflows for PromptSig

Includes ready-to-use components for:

• Prompt execution modals

• DAG visual graph viewer

• Prompt author attribution and tipping

3. 📜 contract-kit

Solana smart contract toolkit and Anchor interfaces for:

• Minting PromptNFTs and SPL-based PromptTokens

• Registering prompts to Vault

• Updating licenses, metadata, and fee structures

• Interacting with PromptDAO governance modules

Includes client bindings and CLI tools for managing on-chain assets directly from developer environments.

Together, these SDKs form the foundation for building everything from simple prompt apps to full AI agents, DAO dashboards, decentralized marketplaces, and on-chain workflow orchestrators.
