Settings Skill

Manages configuration stored at ~/.aibtc/config.json. Controls the Hiro API key used for authenticated Stacks API requests, the custom Stacks API node URL, and provides version information.

Usage

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

Subcommands

set-hiro-api-key

Save a Hiro API key to ~/.aibtc/config.json. Authenticated requests receive higher rate limits than public (unauthenticated) requests.

Get a free API key at https://platform.hiro.so/

bun run settings/settings.ts set-hiro-api-key --api-key <key>

Options:

• --api-key (required) — Your Hiro API key (sensitive value)

Output:

{
  "success": true,
  "message": "Hiro API key saved. All subsequent Hiro API requests will use this key.",
  "maskedKey": "abcd...wxyz",
  "storedIn": "~/.aibtc/config.json"
}

get-hiro-api-key

Check whether a Hiro API key is configured. Shows the key source and a masked preview.

bun run settings/settings.ts get-hiro-api-key

Output (key configured):

{
  "configured": true,
  "source": "~/.aibtc/config.json",
  "maskedKey": "abcd...wxyz",
  "hint": "API key is active. Hiro API requests use authenticated rate limits."
}

Output (no key):

{
  "configured": false,
  "source": "none",
  "maskedKey": "(not set)",
  "hint": "No API key configured. Using public rate limits. Get a key at https://platform.hiro.so/"
}

delete-hiro-api-key

Remove the stored Hiro API key from ~/.aibtc/config.json. If HIRO_API_KEY is set in the environment, that will still be used as a fallback.

bun run settings/settings.ts delete-hiro-api-key

Output:

{
  "success": true,
  "message": "Hiro API key removed from ~/.aibtc/config.json.",
  "envFallbackActive": false,
  "hint": "No API key configured. Requests will use public rate limits."
}

set-stacks-api-url

Point all Stacks API requests at a custom node instead of the default Hiro API. The URL must serve the same /v2/ and /extended/v1/ endpoints as api.hiro.so.

bun run settings/settings.ts set-stacks-api-url --url <url>

Options:

• --url (required) — Base URL of your Stacks API node (e.g. http://localhost:3999)

Output:

{
  "success": true,
  "message": "Custom Stacks API URL saved. All subsequent Stacks API requests will use this node.",
  "url": "http://localhost:3999",
  "storedIn": "~/.aibtc/config.json",
  "tip": "Use get-stacks-api-url to verify, or delete-stacks-api-url to revert to the default."
}

get-stacks-api-url

Show the current Stacks API URL being used. Indicates whether it is a custom node or the default Hiro API.

bun run settings/settings.ts get-stacks-api-url

Output (custom URL):

{
  "activeUrl": "http://localhost:3999",
  "isCustom": true,
  "source": "~/.aibtc/config.json",
  "defaultUrl": "https://api.testnet.hiro.so",
  "network": "testnet",
  "hint": "Using custom Stacks API node."
}

Output (default):

{
  "activeUrl": "https://api.testnet.hiro.so",
  "isCustom": false,
  "source": "default (Hiro API)",
  "defaultUrl": "https://api.testnet.hiro.so",
  "network": "testnet",
  "hint": "Using default Hiro API. Use set-stacks-api-url to point to your own node."
}

delete-stacks-api-url

Remove the custom Stacks API URL and revert to the default Hiro API (api.mainnet.hiro.so or api.testnet.hiro.so).

bun run settings/settings.ts delete-stacks-api-url

Output:

{
  "success": true,
  "message": "Custom Stacks API URL removed. Reverted to default: https://api.testnet.hiro.so",
  "activeUrl": "https://api.testnet.hiro.so",
  "network": "testnet"
}

get-server-version

Check the currently installed package version and compare with the latest published version on npm.

bun run settings/settings.ts get-server-version

Output:

{
  "currentVersion": "0.1.0",
  "latestVersion": "0.1.0",
  "isLatest": true,
  "updateAvailable": false,
  "package": "@aibtc/skills"
}

check-relay-health

Check the health of the x402 sponsor relay and the sponsor address nonce status on-chain. Reports relay reachability, version, sponsor nonce gaps, and mempool congestion.

bun run settings/settings.ts check-relay-health [--relay-url <url>] [--sponsor-address <address>]

Options:

• --relay-url (optional) — Base URL of the sponsor relay (default: https://sponsor.aibtc.dev)
• --sponsor-address (optional) — STX address of the relay sponsor (default: SP1PMPPVCMVW96FSWFV30KJQ4MNBMZ8MRWR3JWQ7)

Output (healthy):

{
  "healthy": true,
  "relay": {
    "url": "https://sponsor.aibtc.dev",
    "reachable": true,
    "status": "ok",
    "version": "1.0.0"
  },
  "sponsor": {
    "address": "SP1PMPPVCMVW96FSWFV30KJQ4MNBMZ8MRWR3JWQ7",
    "lastExecutedNonce": 732,
    "possibleNextNonce": 733,
    "lastMempoolNonce": null,
    "mempoolCount": 0,
    "missingNonces": []
  },
  "issues": [],
  "hint": "Relay and sponsor are operating normally."
}

Output (issues detected):

{
  "healthy": false,
  "relay": { "url": "https://sponsor.aibtc.dev", "reachable": false, "error": "fetch failed" },
  "sponsor": {
    "address": "SP1PMPPVCMVW96FSWFV30KJQ4MNBMZ8MRWR3JWQ7",
    "lastExecutedNonce": 732,
    "possibleNextNonce": 733,
    "lastMempoolNonce": null,
    "mempoolCount": 0,
    "missingNonces": [730]
  },
  "issues": [
    "Relay unreachable: fetch failed",
    "Nonce gaps detected: [730]. Transactions may be stuck. The sponsor may need to fill missing nonces."
  ],
  "hint": "Issues detected — see the issues array for details."
}

Configuration File

All settings are stored in ~/.aibtc/config.json. This file is created automatically on first use by any wallet or settings subcommand.

{
  "version": 1,
  "activeWalletId": null,
  "autoLockTimeout": 15,
  "hiroApiKey": "your-key-here",
  "stacksApiUrl": "http://localhost:3999"
}

Environment Variable Fallbacks

• HIRO_API_KEY — Used if no stored key is set in config
• NETWORK — Set to mainnet or testnet (default: testnet)
• API_URL — Custom x402 relay URL
