Currently recommended tokens: USDT, USDD. ### Quick Start The tool x402_tron_invoke is implemented by the compiled script dist/x402_tron_invoke.js. The script is pre-built and ready to run. You can execute it directly from the command line: # v2 Invoke node dist/x402_tron_invoke.js --url https://api.example.com --entrypoint chat --input '{"prompt": "hi"}' # Direct/Discovery node dist/x402_tron_invoke.js --url https://api.example.com/.well-known/agent.json ### How It Works The x402_tron_invoke tool: Constructs the endpoint URL: If entrypoint is provided: {url}/entrypoints/{entrypoint}/invoke (v2) Otherwise: Uses {url} as-is (v1 / Discovery) Makes a request (POST for v2, GET default for v1) If 402 Payment Required is returned: Parses payment requirements Checks wallet balance and allowance Performs an infinite approval if allowance is insufficient Signs the payment permit (EIP-712 / TRON Typed Data) Retries the request with X-PAYMENT header Returns the response ### Prerequisites Wallet: A TRON private key must be available. The skill automatically looks for it in: TRON_PRIVATE_KEY environment variable. ~/.mcporter/mcporter.json (AIBank standard). x402-config.json in the current/home directory. Tokens: Wallet needs USDT/USDD and some TRX for gas. TronGrid API Key: Required for Mainnet to avoid rate limits (TRON_GRID_API_KEY). ### x402_tron_invoke Invokes an HTTP endpoint with automatic payment handling. Modes: v2 Agent Invoke (Recommended): Provide url (Base URL) + entrypoint. Constructs: {url}/entrypoints/{entrypoint}/invoke Wraps input: {"input": } Method: POST v1 / Direct / Discovery: Provide url (Full URL) without entrypoint. Uses the URL as-is. Method: GET (default) or specified via method. Agent Advice: Use this mode for discovery. If url returns 404, try appending /.well-known/agent.json or /entrypoints. Status Check: Provide --check or --status. Verifies if TRON_PRIVATE_KEY is correctly configured and outputs the associated wallet address. Checks if TRON_GRID_API_KEY is present (Required for Mainnet). Agent Advice: ALWAYS use this instead of env or echo $TRON_PRIVATE_KEY. ParameterTypeRequiredDescriptionurlstringYes*Base URL (v2) or Full URL (v1/Discovery). *Not required for --check.entrypointstringNoEntrypoint name. Required for v2 Invoke.inputobjectNoInput data.methodstringNoHTTP method. Default: POST (v2), GET (Direct).networkstringNomainnet, nile, shasta (Default: nile).checkbooleanNoVerify wallet configuration and output address. ### Example: Chat with Agent (v2 Invoke) node dist/x402_tron_invoke.js --url https://api.example.com --entrypoint chat --input '{"prompt": "Tell me a joke"}' (Sends POST https://api.example.com/entrypoints/chat/invoke) ### Example: Agent Discovery (Direct) Manifest: Fetch agent metadata. node dist/x402_tron_invoke.js --url https://api.example.com/.well-known/agent.json List Entrypoints: List available functions. node dist/x402_tron_invoke.js --url https://api.example.com/entrypoints Each entrypoint typically returns: Path: /entrypoints/{name}/invoke Pricing: Cost in tokens (e.g., 1000 units) Network: Usually nile or mainnet Input Schema: Expected JSON format for the input parameter ### Example: Raw URL (Legacy) node dist/x402_tron_invoke.js --url https://api.example.com/chat --method POST --input '{"prompt": "Tell me a joke"}' ### Cost Reference (USDT/USDD) TokenNetworkContract AddressDecimalsUSDTMainnetTR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t6USDTNileTXYZopYRdj2D9XRtbG411XZZ3kM5VkAeBf6USDTShastaTG3XXyExBkPp9nzdajDZsozEu4BkaSJozs6USDDMainnetTXDk8mbtRbXeYuMNS83CfKPaYYT8XWv9Hz18USDDNileTGjgvdTWWrybVLaVeFqSyVqJQWjxqRYbaK18 Amount (raw)Value (USDT, 6 dec)Typical Use1000$0.001Single API call5000$0.005Multiple results10000$0.01Premium request1000000$1.00Large batch ### Understanding 402 Responses When payment is required, agents return: { "error": "X-PAYMENT header is required", "accepts": [{ "scheme": "exact", "network": "nile", "maxAmountRequired": "1000", "payTo": "T...", "asset": "T..." }], "x402Version": 1 } The tool handles this automatically. ### Supported Tokens This tool supports TRC20 tokens compatible with the x402 protocol. Recommended: USDT (Tether) USDD (Decentralized USD) ### Security Rules for Agents No Private Key Output: The Agent MUST NOT print, echo, or output the TRON_PRIVATE_KEY or any other signing secret to the dialogue context. Internal Loading Only: The Agent should rely on the skill or underlying scripts to load the key internally. No Export Commands: The Agent MUST NOT execute shell commands that contain the private key as a literal string. Sanitized Logs: Ensure that logs or error messages do not leak the key. Silent Environment Checks: If you need to verify if an environment variable is set, use a "Silent Check". Correct: [[ -n $TRON_PRIVATE_KEY ]] && echo "Configured" || echo "Missing" Forbidden: echo $TRON_PRIVATE_KEY, env, printenv, set, export. Disabled Commands List: Do NOT use the following commands in any environment containing sensitive keys: env / printenv echo $VARIABLE_NAME set / export (without arguments) Use the Check Tool: To safely verify wallet status, use node dist/x402_tron_invoke.js --check. ### ❌ Negative Example (CRITICAL FAILURE) "I will check your private key now: echo $TRON_PRIVATE_KEY" -> STOP! This leaks the secret to the logs and UI. ### ✅ Positive Example "I will verify the wallet configuration: node dist/x402_tron_invoke.js --check" -> SAFE. Only the public address is shown. ### "Private key not found" Ensure the TRON_PRIVATE_KEY environment variable is set or a valid x402-config.json exists in the expected locations. ### "Insufficient Allowance" The tool will attempt to broadcast an infinite approve transaction. This requires TRX for gas. Ensure your wallet has TRX. ### "Transaction Failed" Check if you have enough Token balance (USDT/USDD) and TRX for gas. ### Binary and Image Handling If the endpoint returns an image (Content-Type: image/*) or binary data (application/octet-stream): The data is automatically saved to a temporary file (e.g., /tmp/x402_image_...). The tool returns a JSON object with: file_path: Path to the temporary file. content_type: The MIME type of the content. bytes: File size in bytes. Important: The Agent is responsible for deleting the temporary file after it has been used. ### Network Reference NetworkChain IDCAIP-2USDT ContractUSDD ContractTRON Mainnet0x2b6653dceip155:728126428, tron:mainnetTR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6tTXDk8mbtRbXeYuMNS83CfKPaYYT8XWv9HzTRON Nile0xcd8690dceip155:3448148188, tron:nileTXYZopYRdj2D9XRtbG411XZZ3kM5VkAeBfTGjgvdTWWrybVLaVeFqSyVqJQWjxqRYbaKTRON Shasta0x94a9059eeip155:2494104990, tron:shastaTG3XXyExBkPp9nzdajDZsozEu4BkaSJozs- ## Trust - Source: tencent - Verification: Indexed source record - Publisher: wzc1206 - Version: 1.0.0 ## Source health - Status: healthy - Source download looks usable. - Yavira can redirect you to the upstream package for this source. - Health scope: source - Reason: direct_download_ok - Checked at: 2026-05-07T17:22:31.273Z - Expires at: 2026-05-14T17:22:31.273Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/tron-x402-payment) - [Send to Agent page](https://openagent3.xyz/skills/tron-x402-payment/agent) - [JSON manifest](https://openagent3.xyz/skills/tron-x402-payment/agent.json) - [Markdown brief](https://openagent3.xyz/skills/tron-x402-payment/agent.md) - [Download page](https://openagent3.xyz/downloads/tron-x402-payment)
