Frequently Asked Questions
01 What's the best blockchain API for real-time trading data?
Codex offers the best real-time trading data with sub-1-second query response times, WebSocket support for live price updates, and USD pricing translation built-in. While they offer a free tier for testing, production pricing is custom. For transparent pricing with near-real-time data, CoinGecko API's Analyst plan ($129/mo) provides 30-second updates which is sufficient for most trading applications.
02 How much should a trading app budget for blockchain data APIs?
Trading apps typically spend $50-500 per month on blockchain data APIs depending on traffic and update frequency requirements. CoinGecko's Analyst plan at $129/mo (500K calls) suits most medium-traffic apps. High-frequency trading platforms requiring sub-second updates should budget $200-500/mo or negotiate custom enterprise pricing with Codex or Moralis Enterprise.
03 Which blockchain API has the best historical data for backtesting?
CoinGecko API provides the most comprehensive historical data with 10+ years of cryptocurrency price history included in all paid plans starting at $129/mo. The Analyst plan includes 70+ market data endpoints with historical charts, volume data, and market cap tracking essential for trading algorithm backtesting and technical analysis.
04 What's the cheapest blockchain API for a trading app?
Moralis offers the cheapest entry point for production trading apps at $49/mo for 100M compute units per month with 1,500 CU/s rate limit. However, CoinGecko's free Demo plan (10,000 calls/month) or Covalent's free tier (100K credits/month) work well for MVP trading apps during development before scaling to paid plans.
05 Do trading apps need WebSocket support for real-time prices?
WebSocket support significantly improves trading app performance by providing instant price updates without polling. Codex offers WebSocket support for real-time price updates with event-driven architecture. For most retail trading apps, CoinGecko's 30-second REST API updates are sufficient and more cost-effective than implementing WebSocket infrastructure.
06 How much does Blockchain Data APIs software cost?
Most blockchain data apis tools range from $0-15/user/month for basic plans, $20-50/user/month for professional tiers, and $75-150+/user/month for enterprise features. Free tiers typically limit users, storage, or advanced features.
07 What is the best free Blockchain Data APIs tool?
The best free option depends on your needs, but many blockchain data apis platforms offer generous free tiers with core functionality. Check the rankings above for our top free recommendations.
08 Is Blockchain Data APIs software worth the cost?
For most teams, yes. Blockchain Data APIs tools typically pay for themselves through improved efficiency, reduced errors, and better outcomes. Calculate your expected time savings and multiply by your team's hourly rate to determine ROI.
