It provides eight Node.js scripts that cover all major data lookup operations: universal search, account details, transactions, token info, blocks, smart contracts, transfer history, and chain-level statistics. All scripts output structured JSON to stdout and log progress to stderr, following the bankofai skill conventions. ## Prerequisites - **Node.js** >= 16 - **npm** (for installing dependencies) - Run `npm install` in the skill root directory before first use ### API Key (Optional) If no API key is configured, scripts automatically use the **BofAI proxy** (`ts.bankofai.io`) — no setup needed. To use your own TronScan API key instead (higher rate limits), set the environment variable: ```bash export TRONSCAN_API_KEY="your-api-key-here" ``` Get a free key at https://tronscan.org/#/myaccount/apiKeys ### Rate Limits - **Maximum 5 requests per second** - **Maximum 100,000 total requests** on the free-tier key - All endpoints use HTTP GET (except contract event batch queries) - Maximum `limit` per request is 200 (some endpoints allow up to 500) - `start + limit` must be <= 10,000 for paginated endpoints ## Usage Instructions ### 1. Universal Search Search across addresses, tokens, contracts, transactions, and blocks. ```bash node scripts/search.js [--type ] [--limit ] ``` **Parameters:** | Param | Description | Values | |-------|-------------|--------| | `term` | Search query (positional, required) | Any string | | `--type` | Filter result type | `token`, `address`, `contract`, `transaction`, `block` | | `--limit` | Max results | 1–50, default 20 | **When to use:** When you have a partial name, address, hash, or need to identify what something is on TRON. --- ### 2. Account Details Look up account information, balances, token holdings, and resource usage. ```bash node scripts/account.js
# Full account details node scripts/account.js
--tokens [--limit ] # Token holdings node scripts/account.js
--wallet # Portfolio with USD values node scripts/account.js
--resources # Bandwidth & energy node scripts/account.js

Transaction Lookup Retrieve individual transactions by hash or list transactions with filters. ```bash node scripts/transaction.js # By hash node scripts/transaction.js --list [--from ] [--to ] # Filtered list node scripts/transaction.js --stats # Network stats ``` **List options:** | Param | Description | |-------|-------------| | `--from` | Filter by sender address | | `--to` | Filter by receiver address | | `--block` | Filter by block number | | `--start_timestamp` | Start time (ms) | | `--end_timestamp` | End time (ms) | | `--sort` | Sort field (default: `-timestamp`) | | `--limit` | Results per page (default 20, max 200) | | `--start` | Pagination offset | **When to use:** When a user wants to look up a specific transaction hash, or query recent transactions for an address. --- ### 4. Token Information Get token details, pricing, holder lists, supply data, and rankings. ```bash node scripts/token.js --list [--filter ] [--sort ] # Token rankings node scripts/token.js --trc20 # TRC20 detail node scripts/token.js --trc10 # TRC10 detail node scripts/token.js --price [symbol] # Current price node scripts/token.js --holders [--limit ] # Top holders node scripts/token.js --supply # Total supply node scripts/token.js --distribution # Holdings distribution ``` **List filters:** `trc10`, `trc20`, `trc721`, `trc1155`, `all`, `top` **Sort fields:** `priceInTrx`, `gain`, `volume24hInTrx`, `holderCount`, `marketcap` **When to use:** When a user asks about a specific token (price, holders, supply), or wants to browse top tokens on TRON. --- ### 5. Block Information Query block details, recent blocks, or block statistics. ```bash node scripts/block.js # Latest block node scripts/block.js # By block number node scripts/block.js --list --limit # Recent blocks node scripts/block.js --producer
# By block producer node scripts/block.js --stats # Network block stats ``` **When to use:** When a user wants to see the latest block, look up a specific block, or view block production statistics. --- ### 6. Smart Contract Details Look up contract info, energy usage, call statistics, and caller analytics. ```bash node scripts/contract.js
# Contract detail node scripts/contract.js --list [--search ] # Search/list contracts node scripts/contract.js
--energy # Energy consumption node scripts/contract.js
--calls # Call statistics node scripts/contract.js
--callers # Caller list node scripts/contract.js
--analysis --type <0-5> # Daily analytics ``` **Analysis types:** 0=callers, 1=calls, 2=energy, 3=bandwidth, 4=trx_transfers, 5=token_transfers **When to use:** When a user asks about a smart contract's code verification status, usage, energy costs, or who is calling it. --- ### 7. Transfer History Query TRX, TRC10, and TRC20 transfer history for addresses and contracts. ```bash node scripts/transfer.js --trx
# TRX transfers node scripts/transfer.js --trc20
[--token ] # TRC20 transfers node scripts/transfer.js --trc10
[--token ] # TRC10 transfers node scripts/transfer.js --trc20-contract [--addr ] # By contract node scripts/transfer.js --internal
# Internal txns ``` **Common options:** | Param | Description | |-------|-------------| | `--direction` | `0`=all, `1`=incoming, `2`=outgoing | | `--start_timestamp` | Start time (ms) | | `--end_timestamp` | End time (ms) | | `--limit` | Results per page (default 20, max 200) | **When to use:** When a user wants to see transfer history for a wallet — incoming/outgoing TRX, USDT, or other tokens. --- ### 8. Chain Overview & Statistics Get high-level TRON network data, super representatives, governance, and market data. ```bash node scripts/overview.js # Full chain dashboard node scripts/overview.js --tps # Current transactions per second node scripts/overview.js --witnesses # Super Representative list node scripts/overview.js --params # Chain parameters node scripts/overview.js --proposals # Governance proposals node scripts/overview.js --daily-accounts [days] # New account growth node scripts/overview.js --funds # TRX supply & burn data node scripts/overview.js --trx-volume # TRX price/volume history node scripts/overview.js --nodes # Network node map ``` **When to use:** When a user asks about TRON network health, TPS, super representatives, governance, TRX supply, or market data. ## Examples ### Look up a TRON wallet and its USDT balance ```bash # Get full account info node scripts/account.js TDqSquXBgUCLYvYC4XZgrprLK589dkhSCf # Get token holdings with USD values node scripts/account.js TDqSquXBgUCLYvYC4XZgrprLK589dkhSCf --wallet ``` ### Check a transaction ```bash node scripts/transaction.js 7f4a6d28e3c5f1b2a9d8e7c6b5a4f3e2d1c0b9a8f7e6d5c4b3a2f1e0d9c8b7a6 ``` ### Get the current TRX price ```bash node scripts/token.js --price trx ``` ### List top 10 TRC20 tokens by market cap ```bash node scripts/token.js --list --filter trc20 --sort marketcap --limit 10 ``` ### Get recent USDT transfers for an address ```bash node scripts/transfer.js --trc20 TDqSquXBgUCLYvYC4XZgrprLK589dkhSCf --token TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t --limit 10 ``` ### Get chain overview ```bash node scripts/overview.js ``` ## Error Handling All scripts handle errors consistently: | Error | Cause | Solution | |-------|-------|----------| | `Missing required argument` | Required positional arg not provided | Check usage in script header | | `Request failed with status 403` | API key invalid or rate limited | Check `TRONSCAN_API_KEY`, reduce request frequency | | `Request failed with status 404` | Endpoint not found or invalid params | Verify address/hash format | | `timeout of 15000ms exceeded` | API server slow or unreachable | Retry after a few seconds | | `ENOTFOUND` | No network connectivity | Check internet connection | Scripts exit with code 1 on error and output `{ "error": "message" }` to stdout for machine parsing. ## Security Considerations - The API key is **read-only** — it cannot modify blockchain state - The API key is loaded exclusively from the `TRONSCAN_API_KEY` environment variable and is never hardcoded - When no API key is set, requests go through the BofAI proxy (`ts.bankofai.io`) with no key header - Never embed private keys or wallet secrets in script invocations - All queries are **read-only GET requests** against the public TronScan API - The API key should be rotated if ever exposed in logs or public repositories - Rate limit to **5 requests/second** maximum to avoid key revocation ## Common Token Addresses The `resources/common_tokens.json` file contains well-known mainnet token addresses. Key tokens: | Symbol | Contract Address | Decimals | |--------|-----------------|----------| | TRX | *(native)* | 6 | | USDT | TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t | 6 | | USDC | TEkxiTehnzSmSe2XqrBj4w32RUN966rdz8 | 6 | | USDD | TPYmHEhy5n8TCEfYGqW2rPxsghSfzghPDn | 18 | | WTRX | TNUC9Qb1rRpS5CbWLmNMxXBjyFoydXjWFR | 6 | | BTT | TAFjULxiVgT4qWk6UZwjqwZXTSaGaqnVp4 | 18 | | JST | TCFLL5dx5ZJdKnWuesXxi1VPwjLVmWZZy9 | 18 | | SUN | TSSMHYeV2uE9qYH95DqyoCuNCzEL1NvU3S | 18 | Agents can use these addresses directly instead of searching for them. --- *Version 2.0.0 — Created by [M2M Agent Registry](https://m2mregistry.io) for Bank of AI*
