Alchemy API Wrapper

WHAT IT DOES

Alchemy API Wrapper provides access to Alchemy's enhanced blockchain APIs through a simple interface. Enter your Alchemy API key, select a network, and choose an operation — check connection status, fetch token balances for any wallet address using alchemy_getTokenBalances, or retrieve NFT metadata using alchemy_getNFTs. The tool sends JSON-RPC requests to Alchemy's endpoints and displays the results in a structured format. This is essential for developers integrating Alchemy into their applications, testing API keys, exploring Alchemy's enhanced data capabilities, or debugging API calls without writing code.

HOW TO USE

Connect your wallet using the BGWallet bridge (MetaMask or any Web3 wallet). Enter your Alchemy API key — you can obtain one by signing up at alchemy.com. Select the network — Ethereum Mainnet, Goerli, Sepolia, Polygon Mainnet, Arbitrum Mainnet, or Optimism Mainnet. Choose an operation: "Check status" to test the connection and retrieve the chain ID, "Get token balances" to fetch all token balances for a wallet address (requires a wallet address), or "Get NFTs" to retrieve NFTs owned by a wallet address (requires a wallet address). For balance and NFT operations, enter the wallet address in the address field. Click "Execute" to send the API request. Results display the status, network, operation, and structured data (token balances or NFTs) in a table format. Use the "Test connection" button to quickly verify your API key without running a full operation.

TECHNICAL MECHANISM

The tool constructs Alchemy API endpoints based on the selected network and API key, using the format https://{network}.g.alchemy.com/v2/{apiKey}. It sends JSON-RPC POST requests with the appropriate method and parameters. For status checks, it uses eth_chainId. For token balances, it uses the alchemy_getTokenBalances method with an array of addresses. For NFTs, it uses alchemy_getNFTs with a filter object containing the owner address. The tool handles the JSON-RPC response, extracts the result data, and formats it for display. Token balances are displayed with the token contract address and balance. NFTs are displayed with the name, token ID, and contract address. The tool does not store any API keys — they are used only for the current session and discarded on page reload. All requests are sent directly from the browser to Alchemy's API endpoints.

WHAT IT CANNOT SEE

The tool cannot connect to Alchemy without a valid API key — the API key is required for all requests. It cannot store or manage Alchemy API keys securely beyond the current browser session — keys are not persisted across page reloads. It cannot provide full Alchemy SDK functionality beyond basic read operations — it does not support sending transactions, signing messages, or using Alchemy's push APIs. It cannot handle rate limiting or quota management automatically — you must monitor your usage through the Alchemy dashboard. It cannot access Alchemy's enhanced APIs (e.g., NFT floor prices, DEX analytics, or WebSocket streams) without additional configuration. It cannot send transactions or sign messages through the Alchemy API — the tool is read-only. It cannot test API keys for all networks simultaneously — only the selected network is tested. The tool does not sign any transactions.

PLEASE NOTE

This tool works exclusively with EVM-compatible networks supported by Alchemy (Ethereum Mainnet, Goerli, Sepolia, Polygon, Arbitrum, Optimism, and others). Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. The tool does not store any data — all operations are performed client-side. The tool is provided as-is with no warranty or liability. Always verify your Alchemy API key from the Alchemy dashboard. Rate limits apply based on your Alchemy plan (free tier has rate limits).
