Exchange Aggregator Integration: API, Traffic, Conversion

The exchange is live, but there is no traffic. Advertising is expensive, SEO takes six months to show results. Meanwhile, competitors are visible on CoinGecko, Swapzone, ChangeHero. Exchange aggregator integration is a channel that brings 20–40% of all transactions without direct marketing costs. We have been connecting exchanges to these platforms for over 5 years: more than 30 projects, average traffic growth of 30% in the first month. The CPA model allows you to pay only for results, while listing on CoinGecko gives free organic traffic.

How integration with aggregators increases traffic

Getting on a CoinGecko page or into the Swapzone list means being visible to an active audience already ready to exchange crypto. You pay only for the result: CPA (cost per action) or a percentage of the exchange margin. Below is a table of popular aggregators and their terms:

CoinGecko and CoinMarketCap give organic traffic with no fees, but require regular updates of rates and volumes. Swapzone and ChangeHero are direct CPA models: you set the rate, the aggregator drives traffic.

Which aggregators give the best ROI?

Let's compare free and CPA models. CoinGecko provides organic traffic with no deductions — the best ROI if you are listed. Swapzone at an average CPA of 35% gives 2x higher conversion than ChangeHero thanks to quality audience. LetsExchange lags in volume but takes a lower fee. CoinGecko gives 3x more traffic than any other free channel, such as affiliate programs.

Main aggregators and integration types

Swapzone, ChangeHero, LetsExchange

These aggregators specialize specifically in crypto-to-crypto exchanges. Business model: the aggregator shows your rate among others, the user clicks "Exchange" — redirected to you. The aggregator receives CPA or a percentage of the transaction. Swapzone API v2 offers standard endpoints for rates and order creation.

class SwapzoneProvider: """Provide Swapzone with data about our rates""" async def handle_rate_request(self, request: RateRequest) -> RateResponse: """Swapzone requests our rate for a pair""" rate = await self.calculator.get_rate( from_currency=request.from_currency, to_currency=request.to_currency, from_amount=request.amount ) return RateResponse( from_amount=str(request.amount), to_amount=str(rate.to_amount), rate=str(rate.rate), min_amount=str(self.get_min_amount(request.from_currency)), max_amount=str(self.get_max_amount(request.from_currency)), estimated_time_minutes=self.estimate_time(request.from_currency), partner_id=self.PARTNER_ID, partner_extra={} # custom data ) async def handle_create_order(self, order_data: dict) -> CreateOrderResponse: """Swapzone creates an exchange on behalf of the user""" order = await self.exchange_service.create_order( from_currency=order_data['from'], to_currency=order_data['to'], from_amount=Decimal(order_data['amount']), to_address=order_data['address'], refund_address=order_data.get('refund_address'), source='swapzone' # track source ) return CreateOrderResponse( order_id=order.id, deposit_address=order.deposit_address, deposit_amount=str(order.from_amount), receive_amount=str(order.to_amount) ) 

CoinGecko Exchange API

Registration on CoinGecko gives free organic traffic. For this, you need to implement their API tickers:

class CoinGeckoExchangeAPI: """Endpoints that CoinGecko requires from listed exchanges""" async def get_tickers(self) -> list[dict]: """GET /api/v1/tickers — list of active trading pairs with volumes""" pairs = await self.db.get_active_pairs_with_stats() return [ { "base": pair.base_currency, "target": pair.quote_currency, "market": {"name": self.EXCHANGE_NAME, "identifier": self.EXCHANGE_ID}, "last": str(pair.last_rate), "volume": str(pair.volume_24h), "bid_ask_spread_percentage": str(pair.spread_percent), "timestamp": datetime.utcnow().isoformat() + "Z", "is_anomaly": False, "is_stale": pair.last_updated < datetime.utcnow() - timedelta(minutes=5) } for pair in pairs ] 

Why automatic rate updates are critical

If the rate is outdated at the time of payment, conversion drops. Aggregators request real-time rates. A delay of even 30 seconds can cost a deal. We configure caching with a TTL of no more than 10 seconds and use WebSockets for instant notification of changes. This reduces impermanent loss and increases user trust.

Webhook for status notifications

Aggregators often require a webhook to update transaction status:

@app.post("/webhooks/swapzone/status") async def swapzone_status_webhook(data: dict): """Swapzone notifies us about user actions""" order_id = data['order_id'] event = data['event'] # 'payment_sent', 'cancelled', etc. order = await db.get_order(order_id) if event == 'payment_sent': logger.info(f"Swapzone confirmed payment sent for order {order_id}") elif event == 'cancelled': await exchange_service.cancel_order(order_id) @app.get("/webhooks/swapzone/order/{order_id}") async def get_order_status(order_id: str): """Swapzone requests the status of our order""" order = await db.get_order(order_id) return { "status": map_status(order.status), # 'waiting', 'confirming', 'finished', 'failed' "out_tx_hash": order.output_tx_hash, "in_tx_hash": order.input_tx_hash } 

UTM and conversion analytics

Each aggregator should be tagged with UTM parameters for accurate conversion tracking. This can reduce CPA by 40%.

SOURCE_CONFIGS = { 'swapzone': {'utm_source': 'swapzone', 'revenue_share': 0.40}, 'changehero': {'utm_source': 'changehero', 'revenue_share': 0.35}, 'letsexchange': {'utm_source': 'letsexchange', 'revenue_share': 0.30}, 'coingecko': {'utm_source': 'coingecko', 'revenue_share': 0.0}, # CPA model } def track_conversion(order: Order, source: str): config = SOURCE_CONFIGS.get(source, {}) margin = calculate_margin(order) partner_payout = margin * Decimal(str(config.get('revenue_share', 0))) db.create_affiliate_earning(source, order.id, partner_payout) 

Integrating with 5–7 major aggregators ensures a steady flow of transactions without direct advertising costs. Key metric: conversion from click to completed exchange. Typically 15–35% — the main loss is due to KYC friction and outdated rates at the time of payment. Marketing budget savings with this approach can reach 50%.

Integration stages

Basic integration with one aggregator takes 2–4 working days. Full package (5 aggregators + analytics + webhooks) — from 2 to 4 weeks. The cost is calculated individually and depends on complexity and number of sources. Order an integration — our engineers will evaluate your project in one day.
