How MERX Aggregates All Energy Providers Into One API

The TRON energy market in 2026 has a fragmentation problem. At least seven major providers offer energy delegation services, each with their own API, pricing model, and availability patterns. If you want the best price, you need to integrate with all of them, monitor their prices continuously, handle their individual quirks, and build failover logic for when one goes down.

Or you can make one API call to MERX.

This article explains how MERX aggregates all major energy providers into a single API - the architecture behind price monitoring, best-price routing, automatic failover, and the operational simplification that comes from replacing seven integrations with one.

The Provider Landscape

The TRON energy market includes multiple providers, each operating independently. As of early 2026, the major providers include:

• TronSave - one of the earliest energy rental services

• Feee - competitive pricing with API access

• itrx - focus on bulk energy orders

• CatFee - mid-market positioning

• Netts - newer entrant with aggressive pricing

• SoHu - provider with Chinese market focus

• PowerSun - direct staking and delegation

Each provider has their own:

• API format and authentication method

• Pricing structure (some charge per energy unit, others per TRX)

• Minimum and maximum order sizes

• Available durations (1h, 1d, 3d, 7d, etc.)

• Supported payment methods

• Status pages and uptime characteristics

The Integration Tax

Integrating with a single provider is straightforward. Integrating with all of them to get best pricing is a significant engineering undertaking:

Per provider:

• API client implementation: 2-3 days
• Price normalization: 1 day
• Error handling: 1 day
• Testing: 1-2 days
• Ongoing maintenance: 2-4 hours/month

7 providers x 5-7 days = 35-49 days of initial integration 7 providers x 3 hours/month = 21 hours/month ongoing maintenance`

This is the integration tax that MERX eliminates. Instead of maintaining seven provider integrations, you maintain one MERX integration. MERX handles the rest.

The MERX Architecture

MERX sits between your application and the provider ecosystem. The architecture has three core components:

1. Price Monitor

The price monitor is a dedicated service that continuously polls every integrated provider for current pricing. Every 30 seconds, it queries each provider's API, normalizes the response into a standard format, and publishes the result to a Redis pub/sub channel.

Every 30 seconds:  For each provider:

Every 30 seconds:  For each provider:

1. Query provider API for current prices
2. Normalize to standard format (SUN per energy unit)
3. Validate response (reject outliers, stale data)
4. Publish to Redis: channel "prices:{provider}"
5. Store in price history (PostgreSQL)`

The 30-second interval is deliberately chosen. Faster polling would stress provider APIs and add minimal value (prices rarely change second-to-second). Slower polling would risk serving stale prices.

2. Redis Price Cache

Redis serves as the real-time price cache. Every price update from the price monitor is stored in Redis with a TTL (time-to-live) of 60 seconds - twice the polling interval. If a provider's price data is older than 60 seconds, it is automatically expired and excluded from routing decisions.

Redis key structure:  prices:tronsave -> { energy: 88, bandwidth: 2, updated: 1711756800 }  prices:feee -> { energy: 92, bandwidth: 3, updated: 1711756800 }  prices:itrx -> { energy: 85, bandwidth: 2, updated: 1711756800 }  prices:catfee -> { energy: 95, bandwidth: 3, updated: 1711756800 }  ...

Redis key structure:  prices:tronsave -> { energy: 88, bandwidth: 2, updated: 1711756800 }  prices:feee -> { energy: 92, bandwidth: 3, updated: 1711756800 }  prices:itrx -> { energy: 85, bandwidth: 2, updated: 1711756800 }  prices:catfee -> { energy: 95, bandwidth: 3, updated: 1711756800 }  ...

prices:best -> { provider: "itrx", energy: 85, updated: 1711756800 }`

Enter fullscreen mode

Exit fullscreen mode

The prices:best key is recomputed on every price update, giving the API instant access to the current best price without scanning all providers.

3. Order Executor

When you place an order through the MERX API, the order executor receives it and determines the optimal routing:

Order received: 65,000 energy for TBuyerAddress

1. Read prices:best from Redis -> itrx at 85 SUN/unit
2. Check itrx availability for 65,000 energy -> available
3. Submit order to itrx
4. Monitor for on-chain delegation confirmation
5. Verify energy arrived at TBuyerAddress
6. Notify buyer (webhook + WebSocket)`

If the cheapest provider cannot fill the order (insufficient stock, API error, timeout), the executor automatically falls through to the next cheapest provider.

Price Normalization

Different providers quote prices in different formats. Some quote in SUN per energy unit. Some quote total TRX for a given energy amount. Some include bandwidth in the price; others charge separately.

MERX normalizes everything to a single format:

interface NormalizedPrice {  provider: string;  energyPricePerUnit: number; // SUN per energy unit  bandwidthPricePerUnit: number; // SUN per bandwidth unit  minOrder: number; // Minimum energy units  maxOrder: number; // Maximum energy units  availableEnergy: number; // Currently available  durations: string[]; // Supported durations  lastUpdated: number; // Unix timestamp }

interface NormalizedPrice {  provider: string;  energyPricePerUnit: number; // SUN per energy unit  bandwidthPricePerUnit: number; // SUN per bandwidth unit  minOrder: number; // Minimum energy units  maxOrder: number; // Maximum energy units  availableEnergy: number; // Currently available  durations: string[]; // Supported durations  lastUpdated: number; // Unix timestamp }

This normalization is critical. Without it, comparing prices across providers would require the consumer to understand each provider's pricing model. With it, price comparison is a simple numerical sort.

Best-Price Routing in Detail

The routing algorithm is not just "pick the cheapest." Several factors influence the routing decision:

Factor 1: Price

The primary factor. All else being equal, the cheapest provider wins.

Factor 2: Availability

A provider quoting 80 SUN but with only 10,000 energy available cannot fill a 65,000 energy order. The router must check available inventory.

Factor 3: Reliability

MERX tracks each provider's historical fill rate, response time, and failure rate. A provider with a 95% fill rate is penalized relative to one with a 99% fill rate, even if the 95% provider is slightly cheaper.

Effective price = quoted_price / fill_rate

Provider A: 85 SUN, 99% fill rate -> 85.86 effective Provider B: 82 SUN, 94% fill rate -> 87.23 effective Winner: Provider A despite higher quoted price`

Factor 4: Duration Support

Not all providers support all durations. If you need a 1-hour delegation, providers that only offer daily minimums are excluded.

Order Splitting

For large orders that exceed any single provider's capacity, the router splits the order across multiple providers:

Order: 500,000 energy

Provider A: 200,000 available at 85 SUN -> fill 200,000 Provider B: 180,000 available at 87 SUN -> fill 180,000 Provider C: 300,000 available at 92 SUN -> fill 120,000

Total filled: 500,000 energy Blended rate: 87.28 SUN/unit`

The buyer sees a single order with a blended rate. The complexity of multi-provider execution is entirely hidden.

Automatic Failover

Failover is where aggregation truly earns its value. When you integrate directly with a provider and they go down, your application stops functioning. With MERX, provider failures are handled transparently.

Failover Chain

Primary provider fails  |  v Mark provider as unhealthy (exclude from routing for 5 minutes)  |  v Retry with next-cheapest provider  |  v If second provider fails, try third  |  v If all providers fail, return error to buyer with retry guidance

Primary provider fails  |  v Mark provider as unhealthy (exclude from routing for 5 minutes)  |  v Retry with next-cheapest provider  |  v If second provider fails, try third  |  v If all providers fail, return error to buyer with retry guidance

Health Tracking

The price monitor maintains a health score for each provider:

Health score components:

• Last successful price fetch: must be within 60s
• API response time: penalize > 2 seconds
• Recent order fill rate: penalize < 95%
• Recent error rate: penalize > 5%`

Unhealthy providers are excluded from routing until they recover. Recovery is detected automatically when the price monitor successfully fetches prices from them again.

Zero-Downtime for Buyers

From the buyer's perspective, provider failures are invisible. Their API call succeeds as long as at least one provider is operational. In practice, having seven or more providers means that total market outage is essentially impossible - the odds of all providers being down simultaneously are negligible.

One API Replaces Many

Here is what your integration looks like with MERX versus direct provider integration:

Without MERX

// Pseudo-code: direct multi-provider integration

// Initialize 7 provider clients const tronsave = new TronSaveClient(apiKey1); const feee = new FeeeClient(apiKey2); const itrx = new ItrxClient(apiKey3); // ... 4 more

// Fetch prices from all providers const prices = await Promise.allSettled([ tronsave.getPrice(65000), feee.getPrice(65000), itrx.getPrice(65000), // ... 4 more ]);

// Normalize different response formats const normalized = prices .filter(p => p.status === 'fulfilled') .map(p => normalizePrice(p.value)); // complex per-provider logic

// Sort by price, check availability, handle errors... const best = normalized.sort((a, b) => a.price - b.price)[0];

// Place order with best provider try { const order = await getClient(best.provider).createOrder({ energy: 65000, target: buyerAddress, // Provider-specific parameters... }); } catch (e) { // Failover to next provider... // More provider-specific error handling... }`

With MERX

import { MerxClient } from 'merx-sdk';

const client = new MerxClient({ apiKey: 'your-merx-key' });

// Get best price across all providers const prices = await client.getPrices({ energy: 65000 }); console.log(Best: ${prices.bestPrice.provider} at ${prices.bestPrice.perUnit} SUN);

// Place order - automatically routed to best provider const order = await client.createOrder({ energy: 65000, targetAddress: buyerAddress, duration: '1h' });

// Done. Failover, retries, verification handled automatically.`

Seven integrations become one. Hundreds of lines of routing and failover code become four lines. Ongoing maintenance of provider API changes drops to zero.

Real-Time Price Feed

For applications that want to display live prices or make real-time routing decisions, MERX provides a WebSocket price feed:

const client = new MerxClient({ apiKey: 'your-key' });

client.onPriceUpdate((update) => { console.log(${update.provider}: ${update.energyPrice} SUN/unit); console.log(Best price: ${update.bestPrice} SUN/unit); });`

Enter fullscreen mode

Exit fullscreen mode

The WebSocket feed publishes every price update from the price monitor - roughly every 30 seconds per provider. This enables applications to show live pricing without polling.

Provider Transparency

MERX does not hide which provider filled your order. Every order response includes the provider name, the price paid, and the on-chain delegation transaction hash:

{  "orderId": "ord_abc123",  "status": "completed",  "provider": "itrx",  "energy": 65000,  "pricePerUnit": 85,  "totalCostSun": 5525000,  "delegationTxHash": "abc123def456...",  "verifiedAt": "2026-03-30T12:00:00Z" }

{  "orderId": "ord_abc123",  "status": "completed",  "provider": "itrx",  "energy": 65000,  "pricePerUnit": 85,  "totalCostSun": 5525000,  "delegationTxHash": "abc123def456...",  "verifiedAt": "2026-03-30T12:00:00Z" }

Enter fullscreen mode

Exit fullscreen mode

You always know where your energy came from, what you paid, and can verify the delegation on-chain independently.
