## Proxy Requirements

| Marketplace | Datacenter Proxy | Residential Proxy |
|-------------|------------------|-------------------|
| Steam Market | Works | Works |
| DMarket | Works | Works |
| SkinPort | Blocked | Works |
| CSFloat | Rate Limited | Works |
| SkinBaron | Blocked | Works |
| BitSkins | Blocked | Works |

**Recommendation:** Start with Steam + DMarket (no proxy needed). Add residential proxy (Apify or your own via `customProxyUrls`) to unlock more marketplaces.

## Limitations

- Some marketplaces require residential proxy
- Prices are snapshots, not real-time streams
- Exchange rates updated daily
- Float values not available on all marketplaces

## Frequently Asked Questions

### How accurate are the prices?
Prices are fetched in real-time from each marketplace's API. They represent current listing prices, not historical averages.

### Can I use this for automated trading?
Yes! The API returns structured JSON data perfect for trading bots. Many users integrate this with their automated trading systems.

### Why do some marketplaces need proxy?
SkinPort, CSFloat, SkinBaron, and BitSkins block datacenter IPs to prevent scraping. Residential proxies appear as regular users and bypass these blocks.

### How do I get API keys for marketplaces?
- **CSFloat**: https://csfloat.com/api-key (free)
- **Waxpeer**: https://waxpeer.com/profile/api (free with account)
- **BitSkins**: https://bitskins.com/api-key (free with account)

### Is this legal?
Yes. This tool uses public APIs and publicly available price data. It's similar to price comparison websites for any other product.

### How often should I run this?
For arbitrage trading, run every 15-30 minutes. For general price tracking, once per day is sufficient.

### Can I track specific skins over time?
Yes! Use Apify's scheduling feature to run this actor on a schedule and store results in datasets for historical analysis.

### Does this work with BUFF163?
Not yet, but it's on the roadmap. BUFF163 requires Chinese IP proxies due to regional restrictions.
