# Prices API FAQ

> Commonly asked questions when using Alchemy's Prices API for fungible token prices.

> For the complete documentation index, see [llms.txt](/docs/llms.txt).

### How are prices calculated?

[Each endpoint](/docs/reference/prices-api-quickstart#endpoints) has slight different price sources: By Symbol combines CEX and DEX data, whereas By Address only relies on DEX data.

For each token, the price is aggregated by averaging exchange prices (weighted by total volume).

### What tokens do you support?

By Symbol: We support the top 1000+ token symbols by market cap.

By Address: 10K+ tokens from all the leading DEXes.
