General questions
Pricing, which models we serve, payment methods — anything the documentation and FAQ don't already answer.
Enterprise and high volume
For teams whose monthly usage is large enough to want to discuss terms and payment arrangements. FastMetal is a registered qualified invoice issuer in Japan (T5010001015990), bills in Japanese yen, and runs on a prepaid balance. Tell us your expected monthly token volume and which models you plan to use and we can be specific.
Partners, OEM and reselling
For hosting providers, system integrators and agencies who want to offer AI features to their own customers. Our Provisioning API creates accounts, issues API keys and allocates budget programmatically, so per-customer keys and spend limits stay under your control.
Technical support
Authentication errors, model responses, or billing that doesn't match what you expected on a running integration. Include the model name and, where you can, the time of the request.
