How does the credit-based pricing work?

You purchase credits upfront, which are stored in your account balance. Each AI model has a fixed cost per generation (e.g., $0.05 for an image). When you make a successful API call, the corresponding amount is deducted from your credit balance. The key advantages are that credits never expire, you only pay for what you use, and there are no recurring monthly subscriptions. This provides ultimate flexibility and cost control for projects of any size.

What happens if a generation task fails?

PoYo API operates on a strict "no charge for failures" policy. If a task fails due to a system error, API issue, or timeout, you are not charged any credits. You can review the failure reason in your dashboard and choose to manually retry the task. This ensures you only pay for successful, usable outputs, making your credit spending efficient and predictable.

Is there a way to test the API before purchasing credits?

Absolutely. PoYo API provides a fully-featured free playground on each model's page. You can experiment with all generation parameters, test prompts, and see real outputs without using any credits or even providing a credit card. This allows developers to evaluate model quality, fine-tune parameters, and ensure the API meets their needs before any integration or financial commitment.

How do I get support if I encounter integration issues?

PoYo API offers dedicated 24/7 technical support, not just automated bot responses. You can access support through direct channels for integration help, technical questions, and best practices. This is backed by robust monitoring systems ensuring 99.9% uptime. The combination of reliable infrastructure and accessible expert help ensures minimal disruption to your development workflow and production applications.

Do all plans include every AI model?

Yes, every subscription plan grants users full access to Zunvix's comprehensive model catalog for image, video, and voice generation, ensuring that you can utilize all tools regardless of your chosen plan.

Can I use the generated content commercially?

Absolutely. Users retain ownership of their outputs and can utilize them for commercial purposes, provided they respect third-party rights. This empowers creators to monetize their work without legal hurdles.

How do credits work?

Credits in Zunvix are shared across all tools, including image, video, and voice. The number of credits consumed depends on the specific model and task, and credits are renewed each billing cycle, offering flexibility in usage.

Is there support for teams and collaboration?

Yes, Zunvix offers various subscription plans designed for teams, enabling features like batch generation and team sharing. This facilitates collaboration and boosts productivity for teams that are frequently producing content together.
