Frequently Asked Questions
Is there a free tier?
Yes — the Free tier gives you 20 API calls per day with full AI scoring. No credit card required, no time limit.
How do credits work?
Each API call costs a fixed number of credits (e.g. 2 for diagram rendering, 13 for thumbnail ranking). Buy a credit pack, use them across any endpoint, at your own pace.
Can I buy more credits anytime?
Yes! Purchase additional credits whenever you need them. Credits stack — your existing balance carries over.
What payment methods do you accept?
All major credit cards and PayPal through our payment partner Paddle. Paddle handles VAT/GST automatically based on your location.
Do credits expire?
Credits are valid for 3–12 months depending on the pack size. The expiration date is shown at purchase and in your dashboard.
Can I use one API key for all endpoints?
Yes — a single API key works across every CreatorNode API (YouTube, Visual, and future endpoints). No separate keys needed.
Does the MCP server cost extra?
No. The MCP server is free and open-source. It calls the same APIs, so you only pay for the underlying API credits — same pricing as direct REST calls.
What happens when I run out of credits?
You fall back to the Free tier limits (20 calls/day). Purchase more credits anytime to restore your premium rate limits.
