Where CoinAPI falls short, per the models
- GPT Credit and data-volume pricing can become expensive or difficult to predict for high-frequency workloads.
- Claude Data-quality and gap issues on long-tail venues are more common than with Kaiko/Coin Metrics, and credit-metered pricing gets expensive fast at streaming scale.
- Gemini Tiered pricing escalates rapidly for high-volume WebSocket streaming, and DEX/on-chain liquidity coverage remains weaker than centralized exchange coverage.
