Add CowSwap Tracker

[premiumjibles]

Context

The ShapeShift affiliate revenue API aggregates fee data from multiple swap providers. CowSwap (CoW Protocol) is a DEX aggregator that ShapeShift integrates with. Adding CowSwap tracking increases revenue visibility.

Current Problem: CowSwap was listed as "low priority follow-up" in the original handoff but should be implemented for complete revenue tracking.

CowSwap Integration Details

API Base URL: https://api.cow.fi (from ShapeShift app config)

How ShapeShift tracks affiliate: CowSwap uses appData - a hash that encodes metadata including the referrer/affiliate. Need to research how ShapeShift's appData is generated and how to query orders by appData.

Acceptance Criteria

• [ ] Research CowSwap API for order history endpoints
• [ ] Identify how to filter orders by ShapeShift affiliate (appData or other mechanism)
• [ ] Create cowswap.ts tracker following existing patterns
• [ ] Handle pagination if the API requires it
• [ ] Extract fee data from order responses
• [ ] Add 'cowswap' to services array in models.ts
• [ ] Import and call cowswap tracker in index.ts

Files to Create/Modify

• node/proxy/api/src/affiliateRevenue/cowswap.ts (new file)
• node/proxy/api/src/affiliateRevenue/index.ts (add import and integrate)
• node/proxy/api/src/models.ts (add 'cowswap' to services array)

Research Required

1. CowSwap order history API: https://api.cow.fi/docs
2. How appData works for affiliate tracking
3. Whether there's a direct way to query by affiliate/partner

Reference

• CowSwap API docs: https://api.cow.fi/docs
• Main app CowSwap integration: packages/swapper/src/swappers/CowSwapper/ (in shapeshift/web repo)
