What is Alchemy?
The Alchemy skill is a robust integration designed for Openclaw Skills that provides seamless access to the Ethereum blockchain and beyond. Built with a focus on performance and simplicity, it uses only the Python standard library to fetch critical on-chain data including asset transfers, transaction logs, and real-time gas prices.
This skill empowers developers and AI agents to build complex crypto-aware workflows without needing external web3 libraries. By bridging the gap between LLM reasoning and live blockchain state, it facilitates the creation of automated financial assistants, NFT portfolio managers, and chain-monitoring tools within the Openclaw Skills ecosystem.
Alchemy Use Cases
- Building automated NFT portfolio trackers to monitor floor prices and metadata.
- Developing real-time gas price monitoring systems for transaction optimization.
- Creating AI-driven financial audit tools that analyze asset transfers and token balances.
- Implementing blockchain event listeners and log analysis for specific smart contracts.
- Integrating live crypto market data into multi-agent developer workflows.
How Alchemy Works
- The AI agent or user invokes the Alchemy script with a specific command such as get-balance or get-nfts.
- The script authenticates with the Alchemy API using the ALCHEMY_API_KEY environment variable.
- A direct HTTP request is made to the blockchain provider to fetch the requested data.
- The raw blockchain response is parsed and formatted into a structured JSON output.
- The AI agent consumes this JSON data to provide answers or trigger subsequent automated actions within Openclaw Skills.
Alchemy Setup
To use this integration within your Openclaw Skills environment, ensure you have an active Alchemy account and API key.
# Set your environment variable
export ALCHEMY_API_KEY="your_api_key_here"
# Basic command to verify setup
python3 scripts/alchemy.py get-block-number
Alchemy Data Schema & Taxonomy
The skill produces structured JSON outputs tailored to each command. Below is a summary of common data structures returned:
| Data Type | Field Examples |
|---|---|
| Balance | address, balance (in wei or hex) |
| Token Balances | contractAddress, tokenBalance |
| NFT Metadata | name, symbol, tokenType, image_url |
| Transactions | hash, from, to, value, gasUsed |
| Gas Price | hex representation of current gas price |
All responses from Openclaw Skills are optimized for downstream parsing by LLM agents.
Alchemy Advanced Features
