A few things to know

What is included in Free?

1,000 requests per month: item metadata and available daily Steam history for the last 30 completed days. Current prices and other marketplaces require a paid plan.

How fresh is the data?

The pipeline targets 30-minute price refreshes and hourly observations. Check response metadata for actual freshness. This is not a tick-level sniping feed.

Does every item have an all-time history?

Complete coverage is not guaranteed. The API returns stored observations and leaves gaps visible. Asking prices are not completed sales.

How do payments work?

Choose a plan, confirm your invoice and pay with crypto. Access activates after server-side payment verification. There are no automatic charges.
