# Send web3-data-skill to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### Web3 Data Explorer (Chainbase)

Query on-chain data via Chainbase Web3 API and SQL API.

### Quick Reference

API Key: Use env CHAINBASE_API_KEY, falls back to demo. If rate-limited, direct user to https://console.chainbase.com to upgrade.

Script: scripts/chainbase.sh <endpoint> [params...]

# Top token holders
scripts/chainbase.sh /v1/token/top-holders chain_id=1 contract_address=0xdAC17F958D2ee523a2206206994597C13D831ec7 limit=10

# Address labels
scripts/chainbase.sh /v1/address/labels chain_id=1 address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045

# SQL query
scripts/chainbase.sh /query/execute --sql="SELECT * FROM ethereum.blocks ORDER BY number DESC LIMIT 5"

### Chain IDs

ChainIDChainIDEthereum1Optimism10BSC56Base8453Polygon137zkSync324Avalanche43114Merlin4200Arbitrum42161

Default to Ethereum (chain_id=1) unless user specifies otherwise.

### Routing Logic

Match user intent to the right endpoint:

User wantsEndpointTop token holders / who holds a tokenGET /v1/token/top-holdersList of holder addressesGET /v1/token/holdersToken priceGET /v1/token/priceHistorical token priceGET /v1/token/price/historyToken info (name, symbol, supply)GET /v1/token/metadataToken transfer historyGET /v1/token/transfersAddress labels/tagsGET /v1/address/labelsWallet transaction historyGET /v1/account/txsSingle transaction detailGET /v1/tx/detailNative token balance (ETH/BNB)GET /v1/account/balanceERC20 token balances of walletGET /v1/account/tokensNFTs owned by walletGET /v1/account/nftsDeFi portfolio positionsGET /v1/account/portfoliosENS domain lookupGET /v1/ens/records or /v1/ens/reverseNFT metadata/owner/rarityGET /v1/nft/metadata, /owner, /rarityTrending NFT collectionsGET /v1/nft/collection/trendingAnything not covered aboveSQL API (POST /query/execute)

### 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 GET /v1/token/metadata or ask the user for the contract address


Select endpoint — Use the routing table above; fall back to SQL API for complex/custom queries
Execute — Run via scripts/chainbase.sh or direct curl
Present results — Format data clearly with tables for lists, highlight key insights

### SQL API Fallback

When fixed endpoints don't cover the query, translate user intent to SQL:

scripts/chainbase.sh /query/execute --sql="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 complete endpoint parameters and response schemas, read references/api-endpoints.md.
