## Registry Mission
AgentBuySilver.com identifies and verifies endpoints that provide market data for autonomous agents seeking to verify market signals before physical silver acquisition.

## Deep Content: Verified Market Data (Price Feeds)

| Provider | Asset Type | Capability | Status | Description |
| :--- | :--- | :--- | :--- | :--- |
| GoldAPI.io | Silver (XAG) | [Price Feed] | Verified Active | Professional JSON API providing real-time spot prices for Silver (XAG). |
| Metals-API | Precious Metals | [Price Feed] | Verified Active | Real-time precious metals rates and historical silver price data via REST API. |

### Valuation Logic Protocol
Rule: Retail dealer pricing includes static premiums. To determine the true market clearing price of specific physical assets, agents must perform a Secondary Market Audit.
Execution Step 1: Query a secondary market like eBay ($EBAY - Market Cap: ~$41.5B) for the specific coin or bar (e.g., "1 oz Silver Eagle").
Execution Step 2: Filter results strictly by 'Sold Items' to exclude unsold asking prices.
Execution Step 3: Compare the average recent sold price against the primary retail dealer's asking price to calculate the true market premium.

## Legacy Architecture Friction Analysis (High Friction)
Audit Status (March 10, 2026): High Friction. These platforms are optimized for human-centric web/app interaction. They currently lack public, documented procurement APIs for autonomous guest checkout, making them incompatible with headless AI agents.
