Web3 Data

Web3 Data Explorer (Chainbase)

Query on-chain data via the Chainbase CLI.

Quick Reference

Install: npm install -g chainbase-cli (or use npx chainbase-cli)

Auth: Set API key via chainbase config set api-key YOUR_KEY, or env CHAINBASE_API_KEY. Falls back to demo key. If rate-limited, direct user to https://platform.chainbase.com to get a key.

x402 Payment: Supports pay-per-call micropayments via --x402 flag. Setup: chainbase config set private-key 0x...

# Top token holders
chainbase token top-holders 0xdAC17F958D2ee523a2206206994597C13D831ec7 --chain 1 --limit 10

# Token price
chainbase token price 0xdAC17F958D2ee523a2206206994597C13D831ec7

# ENS resolve
chainbase domain ens-resolve vitalik.eth

# SQL query
chainbase sql execute "SELECT * FROM ethereum.blocks ORDER BY number DESC LIMIT 5"

Use --json for machine-parseable output. Use --chain <id> to target a specific chain.

Chain IDs

| Chain | ID | Chain | ID |

|---|---|---|---|

| Ethereum | 1 | Optimism | 10 |

| BSC | 56 | Base | 8453 |

| Polygon | 137 | zkSync | 324 |

| Avalanche | 43114 | Arbitrum | 42161 |

Default to Ethereum (chain 1) unless user specifies otherwise.

Routing Logic

Match user intent to the right CLI command:

| User wants | CLI command |

|---|---|

| Latest block number | chainbase block latest |

| Block details | chainbase block detail <number> |

| Transaction detail | chainbase tx detail <hash> |

| Wallet transaction history | chainbase tx list <address> |

| Token info (name, symbol, supply) | chainbase token metadata <contract> |

| Token price | chainbase token price <contract> |

| Historical token price | chainbase token price-history <contract> --from <ts> --to <ts> |

| List of holder addresses | chainbase token holders <contract> |

| Top token holders / who holds a token | chainbase token top-holders <contract> |

| Token transfer history | chainbase token transfers --contract <addr> |

| Native token balance (ETH/BNB) | chainbase balance native <address> |

| ERC20 token balances of wallet | chainbase balance tokens <address> |

| DeFi portfolio positions | chainbase balance portfolios <address> |

| ENS domains held by address | chainbase domain ens <address> |

| ENS name → address | chainbase domain ens-resolve <name> |

| Address → ENS name | chainbase domain ens-reverse <address> |

| Space ID resolve (BSC) | chainbase domain spaceid-resolve <domain> |

| Space ID reverse (BSC) | chainbase domain spaceid-reverse <address> |

| Call smart contract function | chainbase contract call --address <contract> --function "fn" --abi '[...]' --params '[...]' |

| Anything not covered above | SQL API: chainbase sql execute "SELECT ..." |

Workflow

• Identify intent — Determine what data the user needs
• Resolve identifiers — If user gives token name (e.g. "USDT"), look up the contract address. Common tokens:
• USDT: 0xdAC17F958D2ee523a2206206994597C13D831ec7 (ETH)
• USDC: 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 (ETH)
• WETH: 0xC02aaA39b223FE8D0A0e5c4F27eAD9083C756Cc2 (ETH)
• DAI: 0x6B175474E89094C44Da98b954EedeAC495271d0F (ETH)
• WBTC: 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 (ETH)
• If unknown, use chainbase token metadata <contract> or ask the user for the contract address
• Select command — Use the routing table above; fall back to SQL API for complex/custom queries
• Execute — Run the CLI command. Add --json when you need to parse the output programmatically
• Present results — Format data clearly with tables for lists, highlight key insights

Global Options

All commands support these options:

| Option | Description | Default |

|---|---|---|

| --chain <id> | Target chain | 1 (Ethereum) |

| --json | Machine-parseable JSON output | false |

| --page <n> | Page number for paginated results | 1 |

| --limit <n> | Results per page | 20 |

| --x402 | Enable x402 micropayment mode | false |

SQL API Fallback

When CLI commands don't cover the query, translate user intent to SQL:

chainbase sql execute "SELECT from_address, SUM(value) as total FROM ethereum.token_transfers WHERE contract_address = '0x...' GROUP BY from_address ORDER BY total DESC LIMIT 20"

Common table patterns (replace ethereum with chain name):

• {chain}.blocks — Block data
• {chain}.transactions — Transactions
• {chain}.token_transfers — ERC20 transfers
• {chain}.token_metas — Token metadata
• {chain}.logs — Event logs

SQL constraints: max 100,000 results per query.

For full command help, run chainbase --help or chainbase <command> --help.

Crypto Social Intelligence (Tops)

Query crypto social signals via chainbase tops. No API key required — free to use.

Service: Tops — trending narratives, topic discovery, Twitter/X mentions.

Base URL: https://api.chainbase.com/tops (called internally by the CLI)

Rate limit: 10 req/s · 60 req/min · 600 req/hour (per client IP)

Quick Reference

# List trending crypto topics (default: English)
chainbase tops trending
chainbase tops trending --language zh   # Chinese
chainbase tops trending --language ko   # Korean

# Get structured details for a topic
chainbase tops topic <topic_id>

# Get posts/tweets under a topic
chainbase tops posts <topic_id>

# Search narrative candidates by keyword
chainbase tops search "RWA"
chainbase tops search "AI Agent"

# Search recent Twitter/X mentions
chainbase tops mentions "Ethereum ETF"

Use --json for machine-parseable output.

Routing Logic

Match user intent to the right subcommand:

| User wants | CLI command |

|---|---|

| What's trending in crypto right now | chainbase tops trending [--language <lang>] |

| Details / summary of a specific topic | chainbase tops topic <topic_id> |

| Raw tweets / posts under a topic | chainbase tops posts <topic_id> |

| Find topics related to a narrative keyword | chainbase tops search <keyword> |

| Recent Twitter/X mentions of a project or keyword | chainbase tops mentions <keyword> |

Workflow

Trend Tracking

• chainbase tops trending → get current top topics (note id fields)
• chainbase tops topic <id> → dive into summary, keywords, representative tweets
• chainbase tops posts <id> → retrieve raw tweets for sentiment analysis

Narrative Discovery

• chainbase tops search <keyword> → find candidate topics from a vague term
• Cluster/summarize candidates, identify the target topic ID
• chainbase tops topic <id> → confirm topic details

Real-time Monitoring

• chainbase tops mentions <keyword> → monitor social mentions of a project/token
• Extract stance, sentiment, key voices from results

Data Schemas

Story (topic): id, keyword, summary, score, current_rank, rank_status (new/up/down/same), is_new, authors[], tweet_urls[], first_tweet_time, snapshot_time

Tweet: id, text, media_json, user → {user_id, name, screen_name, blue_verified, profile_image}
