What is MERX

MERX is the infrastructure layer for AI agents and agentic networks on TRON. Where Stripe is infrastructure for web commerce and Cloudflare for the open web, MERX is the missing infrastructure layer that lets autonomous AI agents discover, transact, and operate on TRON without ever touching energy, bandwidth, or low-level blockchain mechanics.

The platform exposes one coherent stack: 66-tool MCP server, agent payment service for TRC-20 stablecoins, x402 v2 facilitator (the only TRON facilitator in the coinbase/x402 ecosystem registry), GasFree transfers via a MERX-deployed mainnet controller, dedicated TRON RPC node, A2A (Google, 7 skills) and ACP (BeeAI, 7 capabilities) protocol coverage, and a natural language Policy Engine powered by Anthropic Claude.

Underneath those agent surfaces sits an energy aggregator across 6 active providers (CatFee, Netts, TronSave, iTRX, PowerSun, TEM) that routes resource purchases to the cheapest source automatically -- so when an agent calls send(), MERX estimates the energy required, buys only the deficit, and broadcasts the transaction. The agent never holds TRX or thinks about energy.

Any AI agent running in Claude, LangChain, CrewAI, Vertex AI, AutoGen, or BeeAI can send payments and acquire resources on TRON through a single integration with MERX.

Three ways to plug an agent into MERX:

• MCP server -- 66 tools for AI agents. Hosted SSE at https://merx.exchange/mcp/sse (zero install) or local stdio via npx merx-mcp. Works with Claude, GPT, Cursor, Windsurf, and any MCP-compatible client.

• Claude Code plugin -- one-line install for Claude Code. Auto-registers the MCP server, ships 6 slash commands and a tron-agent-engineer sub-agent. See Hovsteder/merx-claude-plugin.

• REST API + SDKs -- direct programmatic access for agents that aren't using MCP. JavaScript (merx-sdk v2.1 on npm), Python (merx-sdk v2.1 on PyPI), or raw HTTP against /api/v1/ (70+ versioned endpoints).

For human users, the web platform at merx.exchange remains available for manual energy trading, dashboard, deposits, and withdrawals -- but the platform is built primarily for agents.

The problem

AI agents will become the dominant transactional users of stablecoins, and TRON -- home to USDD, $86B+ USDT, USDC, and the dominant chain for retail USDT in Southeast Asia, Africa, and Latin America -- is already the largest USDT-native network in the world.

But TRON has no infrastructure designed for agents:

• No agent-native payment service. Existing TRON wallets are built for human users with mouse clicks and seed-phrase backups, not for autonomous programs that need to register addresses, send TRC-20s, watch for incoming payments, and create invoices via REST.

• Energy and bandwidth are a UX dead-end. Every smart contract call on TRON requires energy. Without energy, TRX tokens burn as fees -- a single USDT transfer burns 3-13 TRX (~$1-4) for cold receivers. Renting energy from a provider drops the cost to ~$0.10 -- a 94% reduction -- but every provider has a different price, different API, different duration tiers, and different failure modes. No agent can be expected to manage that.

• No x402 facilitator on TRON before MERX. The x402 protocol has already processed $43.57M in agent-to-agent payments on Base, Solana, Stellar, and Ethereum. TRON was completely absent from the coinbase/x402 ecosystem registry until MERX. Agents that wanted to pay for TRON-hosted APIs in USDT had no standardized way to do it.

• Three agent protocols, zero TRON integrations. MCP (Anthropic), A2A (Google), and ACP (BeeAI) are the three major agent communication protocols. Until MERX, none of them had a deployed, production-grade TRON server. AI agents in Claude, Vertex AI, or BeeAI literally could not see TRON.

MERX builds the missing layer. AI agents call one API, hold zero TRX, and get paid / pay / send / receive in USDT, USDC, or USDD on the world's largest USDT network.

| Without MERX | With MERX | |---|---| | Agent has to manage energy + bandwidth manually | send() estimates and provisions resources automatically | | Agent has to hold TRX as gas | GasFree transfers — agents send stablecoins from zero-TRX wallets | | Agent has to integrate every energy provider's API | One MERX API routes to the cheapest of 6 providers | | No way to pay for TRON-hosted APIs in USDT | x402 v2 facilitator with full USDT/USDC/USDD support | | No A2A/ACP discovery on TRON | Agent Card + Manifest live, 7 skills, 7 capabilities | | Agent has to write its own MCP server for TRON | 66 tools, 30 prompts, 21 resources, hosted | | Address watching means polling RPC | watch() with sub-3-second webhook delivery via ZMQ |

Quick start

Four paths depending on your use case. For AI agents, paths 3 and 4 are the primary surfaces. Path 1 (web) is for human operators; path 2 (REST/SDK) is for direct programmatic integration.

Path 1: Web platform (humans)

Go to merx.exchange. Sign in. Deposit TRX. Manage energy, agent API keys, and balance through the dashboard. No code required.

Path 2: REST API / SDK (programmatic)

Install the JavaScript SDK:

npm install merx-sdk

Use it in your application (replace merx_sk_your_key with your API key from merx.exchange):

import { MerxClient } from 'merx-sdk'

const merx = new MerxClient({ apiKey: 'merx_sk_your_key' })

// Get current prices from all providers
const prices = await merx.prices.list()
console.log(prices[0])
// { provider: "netts", price_sun: 22, available: 100000000 }

// Buy energy at best price
const order = await merx.orders.create({
  resource_type: 'ENERGY',
  amount: 65000,
  duration_sec: 300,
  target_address: 'TYourAddress...',
})
console.log(order.status)   // "FILLED"
console.log(order.cost_trx) // 1.4311

Python:

from merx import MerxClient

merx = MerxClient(api_key="merx_sk_your_key")

prices = merx.prices.list()
order = merx.orders.create(
    resource_type="ENERGY",
    amount=65000,
    duration_sec=300,
    target_address="TYourAddress..."
)

curl (no SDK needed):

# Public -- no auth required
curl https://merx.exchange/api/v1/prices

# Authenticated
curl -X POST https://merx.exchange/api/v1/orders \
  -H "Authorization: Bearer merx_sk_your_key" \
  -H "Content-Type: application/json" \
  -d '{
    "resource_type": "ENERGY",
    "amount": 65000,
    "duration_sec": 300,
    "target_address": "TYourAddress..."
  }'

Path 3: Claude Code plugin (one-line install)

If you're using Claude Code, this is the fastest path. The plugin auto-registers the hosted MCP server, ships 6 slash commands, and includes a tron-agent-engineer sub-agent specialized in agentic payment workflows on TRON.

/plugin marketplace add Hovsteder/merx-claude-plugin
/plugin install merx@merx

Then run /merx:setup to configure your MERX API key. Available commands:

| Command | What it does | |---|---| | /merx:setup | First-time setup: API key, connection test, capability tour | | /merx:prices | Live TRON energy and bandwidth prices across all providers | | /merx:buy-energy | Buy energy via cheapest provider, delegated to a target address | | /merx:balance | MERX prepaid balance, recent orders, free-tier usage | | /merx:tx | Look up a TRON transa
