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

  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:

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

  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}
