Skills

web3-tools

Multi-chain blockchain data querying skill powered by the Nodit API. Requires an API key for authentication.

Use when:

• Querying token / NFT balances and metadata
• Looking up transactions and analyzing transfer history
• Fetching block data
• Reading smart contract state (eth_call)
• Resolving ENS names
• Monitoring on-chain events (Webhook)
• Estimating and checking gas fees
• Analyzing token holders and transfer history

Supported APIs:

API Type	Description	Format
Data API	Indexed blockchain data (balances, NFTs, tokens, statistics, etc.)	REST
Node API	Direct blockchain node calls (JSON-RPC)	JSON-RPC
Aptos Indexer API	Indexed Aptos data	GraphQL
Webhook API	On-chain event subscription management	REST

Supported Chains:

Ethereum, Arbitrum, Base, Optimism, Polygon, BNB, Kaia, Luniverse, Giwa, Arc, Chiliz, Ethereum Classic, Solana, Sui, Aptos, Bitcoin, Bitcoin Cash, Dogecoin, Tron, XRPL

web3-x402

Access the Nodit API without an API key — pay with USDC via the x402 protocol instead.

Works alongside the web3-tools skill: this skill handles wallet-based authentication and billing, while web3-tools provides the API specs and parameters.

Use when:

• Querying blockchain data without an API key
• Building autonomous agents that call APIs with wallet-based auth
• Using SIWX authentication (SIWE for EVM, SIWS for Solana)
• Credit mode: pre-charge USDC, then deduct credits per request
• PPU mode: pay on-chain USDC per individual request

Payment Modes:

Mode	Flow	Best For
Credit	SIWX auth → charge USDC → deduct credits per call	Repeated API usage
PPU (Pay-Per-Use)	Request → 402 response → pay per request	One-off calls

Payment Networks:

Network	Use
Base Mainnet	Production
Base Sepolia	Testnet
Solana Mainnet	Production
Solana Devnet	Testnet

Requirements

• web3-tools: Requires a Nodit API key (free sign-up)
• web3-x402: No API key needed — requires a wallet with USDC
