The first. The leader. The company.
Steam data is our business — not a side project.
Since 2018, run by engineers who do this full time — on our own servers, monitored around the clock. That is why production teams put us behind their revenue.

A real company, not a side project.
No AI wrapper, no reseller. A team of experienced engineers who have been shipping Steam infrastructure since 2018 — through every Steam API change, every rate-limit tightening, every CS2 migration.
We operate our own servers, our own collection pipelines and our own monitoring. When something breaks at 3am, a human is on it — not a queue.
The marketplaces and tools people already use run on this API.
Not pilot projects — live products with paying users, serving Steam data through our endpoints every day.

Production dashboard
How we operate.
A clear view of our platform, operating practices and verifiable business identity — for technical and procurement teams alike.
Public operations
Service health and incidents are published on an external status page so teams can verify current availability independently.
Open system status →Data coverage and freshness
Product and marketplace pages expose coverage, sources and update times. Coverage differs by product and marketplace and it is stated where the data is used.
Review market coverage →API compatibility
Existing API routes, query-key authentication and response contracts remain supported. X-Api-Key is the recommended authentication method for new integrations.
Read documentation →Support and incidents
Support requests are triaged through established support channels. Enterprise agreements can define escalation paths, response expectations and incident communication.
Contact support →Commercial readiness
Business invoicing, individually scoped contracts, higher limits, custom delivery and individually agreed service levels are available for qualified enterprise requirements.
Enterprise options →Verified European operator
Steamwebapi is operated by the German-registered Sellrock UG (haftungsbeschränkt), registered with the Local Court of Nürnberg under HRB 44731. Full legal and VAT details remain in the imprint.
Verify legal details →Availability measured in public, not self-reported.
Every endpoint is monitored around the clock. Incidents, response times and the full history stay on the public status page — verify it before you sign anything.
Availability, incidents and response times are published — not described.
