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

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

Routing Logic

Match user intent to the right CLI command:

Workflow

1. Identify intent — Determine what data the user needs
2. 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
3. Select command — Use the routing table above; fall back to SQL API for complex/custom queries
4. Execute — Run the CLI command. Add --json when you need to parse the output programmatically
5. Present results — Format data clearly with tables for lists, highlight key insights

Global Options

All commands support these options:

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:

Workflow

Trend Tracking

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

Narrative Discovery

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

Real-time Monitoring

1. chainbase tops mentions <keyword> → monitor social mentions of a project/token
2. 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}
