Frequently asked
What key do I get?
A service key issued by us that only works against this gateway. Upstream vendor keys are never shared, and we do not sell or share upstream accounts.
Are Codex Pro, GPT Pro and Claude top-ups the same service?
Account top-ups follow the listed product. Search terms such as Codex Pro and GPT Pro do not define a plan: check the specific ChatGPT Pro product and its Codex usage terms. Claude top-ups are offered only when an available product is listed. Account subscriptions do not add gateway API balance.
How do I get the free allowance? Do I need to leave a review?
Students in related fields, developers with a learning or research purpose, and open-source maintainers can prepare an application. Reviews consider use and available places. Allowance, models and validity are confirmed before issue; no review, share or referral is required.
Can a company get an invoice?
Yes, for real, paid technical or software services only, matching the actual work and amount. Free-tier usage is never invoiced.
Do you keep my prompts?
The gateway records only the metadata needed for billing and debugging. See the security page for retention and revocation; use BYOK for sensitive code.
