Moralis Data Fetcher

WHAT IT DOES

Moralis Data Fetcher provides access to Moralis' unified blockchain data APIs through a simple interface. Enter your Moralis API key, select a chain (Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, Avalanche, or Fantom), and choose an operation — check API status, fetch token balances for any wallet, retrieve NFTs, get transaction history, or view portfolio data. The tool sends authenticated requests to Moralis' REST API endpoints and displays the results in formatted tables. This is essential for developers integrating Moralis into applications, testing API keys, exploring Moralis' 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 Moralis API key — you can obtain one by signing up at moralis.io. Select the chain — Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, Avalanche, or Fantom. Choose an operation: "Check status" to test the connection, "Get token balances" to fetch all ERC-20 token balances for a wallet address, "Get NFTs" to retrieve NFTs owned by a wallet, "Get transaction history" to view recent transactions, or "Get portfolio" to see a wallet's portfolio with USD values. For data operations, enter the wallet address in the address field. Click "Execute" to send the API request. Results display the status, chain, operation, and formatted data (token balances, NFTs, transactions, or portfolio) in a structured table format.

TECHNICAL MECHANISM

The tool constructs Moralis API endpoints using the base URL https://deep-index.moralis.io/api/v2 and appends the appropriate path for each operation. It includes the API key in the X-API-Key header and sends GET requests with query parameters for chain and other filters. For status checks, it calls the /web3/version endpoint. For token balances, it uses /{wallet}/erc20. For NFTs, it uses /{wallet}/nft. For transactions, it uses /{wallet} to fetch the transaction history. For portfolio data, it uses /{wallet}/portfolio. The tool parses the JSON responses and formats the data into tables. Token balances are displayed with the token address, symbol, formatted balance (using decimals), and decimal places. NFTs are displayed with name, token ID, contract address, and amount. Transactions are displayed with hash, from, to, value, and block number. Portfolio data displays token name, symbol, balance, and USD value. All requests are sent directly from the browser to Moralis' API endpoints.

WHAT IT CANNOT SEE

The tool cannot connect to Moralis without a valid API key — the API key is required for all requests. It cannot store or manage Moralis API keys securely beyond the current browser session — keys are not persisted across page reloads. It cannot provide full Moralis SDK functionality beyond basic read operations — it does not support real-time streams, WebSocket connections, or push notifications. It cannot handle rate limiting or quota management automatically — you must monitor your usage through the Moralis dashboard. It cannot access Moralis's real-time streams or WebSocket APIs without additional configuration. It cannot send transactions or sign messages through the Moralis API — the tool is read-only. It cannot fetch data for chains not supported by the selected chain list. It cannot test API keys for all chains simultaneously — only the selected chain is tested. The tool does not sign any transactions.

PLEASE NOTE

This tool works exclusively with EVM-compatible chains supported by Moralis (Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, Avalanche, Fantom, 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 Moralis API key from the Moralis dashboard. Rate limits apply based on your Moralis plan (free tier has rate limits). For production use, always secure your API keys server-side.
