To retrieve wallet balances and transaction history across EVM-compatible chains, you use this Skill to query on-chain data through an API proxy. It requires an Obul API key for automatic payment processing and returns the requested wallet data.

Blockchain transaction simulation safely tests transactions before execution to preview outcomes and prevent costly errors. You need it when verifying smart contract interactions or token transfers without actually broadcasting to the network or spending gas.

Yes, you can resolve ENS names to wallet addresses and vice versa using this Skill. It provides ENS name resolution as a core feature, allowing you to convert human-readable Ethereum domain names to cryptographic addresses.

Yes, you need an Obul API key to access token prices and PnL analysis because the Skill uses it for authentication and automatic pay-per-use payment processing. The key links requests to the proxy provider for billing.

The best way to get real-time token metadata without running a node is using a pay-per-use blockchain analytics proxy. This Skill abstracts node interaction complexities, fetching real-time token prices and metadata via an API.

The primary limitation of pay-per-use blockchain data retrieval is cost scaling; high-volume analytics incur automatic micro-charges per request via the Obul proxy. It is designed for on-demand queries rather than continuous heavy data extraction.
