What this skill does

# 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

Get current STX fee estimates for different priority levels.

```
bun run query/query.ts get-stx-fees

```json

  "fees": {
    "low": { "microStx": 1000, "stx": "0.001 STX", "description": "Lower fee, may take longer to confirm" },
    "medium": { "microStx": 2500, "stx": "0.0025 STX", "description": "Standard fee, typical confirmation time" },

- `--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:
```json
{
  "contractId": "SP...contract-name",

  "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: testnet)
- `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
