API usage & privacy
Key Checker routes each storefront form to its matching validation service. Submitted codes are checked server-side; we do not publish or resell voucher contents.
How checks work
The site provides 49 checker endpoints covering game launchers, gift cards, and reseller marketplaces. When you press Process, the code is sent to our check gateway, validated for format, then looked up against the upstream provider where that adapter is available.
Each checker talks to the official storefront or publisher API through a dedicated adapter node. We never ask for your account password — only the voucher string you paste into the form.
Rate limits apply per IP to keep upstream APIs stable. Repeated failures or malformed codes return an error without charging queue priority.
Data handling
Submitted voucher strings are transmitted over HTTPS to the check worker, compared against provider databases, and discarded from active processing once the response is returned. Aggregated statistics (success / failure counts) may be retained for capacity planning; individual codes are not indexed for resale.
We do not require registration. Optional cookies may remember sidebar preferences and anonymous visit counters — see the cookie banner for details.
Provider integration (reference)
| Storefront adapters | Per-checker routes proxied through our gateway (Steam, Epic, PlayStation, Xbox, Nintendo, Minecraft, and others). Each adapter validates format locally, then queries the publisher or store API when online. |
|---|---|
| Catalog enrichment | When a provider returns a product identifier, we may fetch public catalog metadata (title, artwork) to show a gift preview on valid lookups. |
| Legacy adapters | Older storefront workers (Stadia, Desura, etc.) may be offline during maintenance — see the status page. |
Summary
| Transmission | HTTPS to check workers on submit |
|---|---|
| Retention | Discarded after lookup; aggregate metrics only |
| Accounts | Not required |
| Affiliation | Independent tool — not affiliated with listed publishers or stores |
