Query Skill

Provides Stacks network and blockchain query operations using the Hiro API. No wallet required for most queries; get-account-info and get-account-transactions fall back to the active wallet address if no address is provided.

Usage

bun run query/query.ts <subcommand> [options]

Subcommands

get-stx-fees

• --contract-id (required) — Contract ID in format address.contract-name
• --function-name (required) — Name of the read-only function
• --args (optional) — JSON array of hex-encoded Clarity values (default: [])
• --sender (optional) — Sender address (uses active wallet or contract address if omitted)

The --args option accepts a JSON array of hex-encoded Clarity values. Use @stacks/transactions to encode values. For example, uintCV(1) serialized as hex would be "0100000000000000000000000000000001".

Output:

{

  "cause": null
}

Notes

• All queries use the Hiro API (api.mainnet.hiro.so or api.testnet.hiro.so)
• Network is controlled by the NETWORK environment variable (default: mainnet)
• get-account-info and get-account-transactions fall back to the active wallet address
• call-read-only falls back to the contract's own address as sender if no wallet is active
