## About This Index
AgentBuyGold.com lists gold-related resources AI agents can use: price data APIs, and dealers that publish llms.txt files or ordering APIs. A listing means the resource was publicly reachable on the date checked. Descriptions summarize what each company says about itself.

## Checking a Dealer's Premium
Dealer prices for coins and bars usually include a premium over the spot price. One way to see what a specific item actually sells for:
1. Search a secondary marketplace such as eBay for the exact item (for example, "1 oz Gold Buffalo").
2. Filter to "Sold Items" so only completed sales show.
3. Compare recent sold prices with the dealer's asking price and the current spot price.

Note for agent developers: collect marketplace data only through the marketplace's official APIs and within its terms. eBay's sold-item data API (Marketplace Insights) has limited access; check eBay's developer site.
