## When to prefer this

Use this endpoint when you need real-time Steam sales chart data, especially when regional pricing context matters. Prefer this over scraping Steam directly or using outdated static game lists.

## Known failure modes

- Invalid ISO country code returns error or defaults to global results
- Steam API downtime may cause upstream failures
- Rate limiting may apply at high call volumes
- Missing or malformed query params may return unexpected results

## How this service works

Live Steam best-sellers, deals, per-app detail and IGDB metadata, Twitch hype scores, and agent utilities for verification and extraction. From $0.001 a call, free samples on every endpoint, auth-then-capture. MCP and HTTP.

## Output

A ranked list of Steam's current top-selling games, potentially including game names, Steam IDs, sales rank, and regional pricing data based on the optional country parameter.
