Question 1

Is the CoinGecko API or the CoinMarketCap API better for market data?

Accepted Answer

Both are strong and close. CoinGecko API leads on exchange reference breadth. CoinMarketCap API is the trusted price brand. For wallet and portfolio data, neither covers it. CoinStats API does, at a lower price.

Question 2

Which crypto data API is cheapest?

Accepted Answer

CoinStats API, per call. It runs roughly 4x to 7x faster than the CoinMarketCap and CoinGecko APIs. Its free tier also supports commercial use.

Question 3

Do the CoinGecko or CoinMarketCap APIs return wallet balances by address?

Accepted Answer

No. Both center on market and onchain DEX data. Neither returns balances, transactions, or DeFi positions per address. CoinStats API does.

Question 4

How does a data API differ from a node provider like GetBlock?

Accepted Answer

A node provider gives direct RPC access to a chain. A data API reads and normalizes that data across many chains. Most apps use both together.

Question 5

Which crypto API is best for a portfolio app?

Accepted Answer

CoinStats API. One key spans market data, balances, transactions, P&L, DeFi positions, and exchange sync.

Question 6

Do these APIs support AI agents and MCP?

Accepted Answer

All three offer AI and MCP access. The CoinStats MCP Server also exposes wallet, DeFi, and portfolio data, not prices alone.

Question 7

Which crypto API has a commercial-free tier?

Accepted Answer

CoinStats API. Its free tier gives 20,000 credits a month, with commercial use included. The CoinMarketCap free tier is personal only.

Question 8

Can CoinStats API replace CoinGecko API or CoinMarketCap API?

Accepted Answer

For most apps, yes. It matches the market data. Then it adds wallet, DeFi, and portfolio data under one key.

Question 9

Does CoinStats API cover DeFi positions and token security?

Accepted Answer

Yes. It resolves DeFi across 10,000+ protocols. The Token Risks endpoint flags honeypots and contract risk on the free tier.
