Build vs Plan mode are both included — answering questions and reviewing a plan in
Plan mode costs nothing; you only spend credits when a build actually runs.
What a credit is
A credit is the unit you spend on a generation. One action — a new project, an edit — costs a fixed number of credits, charged when the build starts and refunded in full if the build fails.What actions cost
| Action | Cost | What you get |
|---|---|---|
| New project | 3 credits | A full project scaffolded from your prompt, in a new private repository |
| Edit | 2 credits | A change applied to an existing project (a new commit) |
| Template remix | 5 credits | A ready-made multi-page template forked into your own project |
| Sign-up bonus | +5 free | Granted once, when you confirm your account |
Packs
You buy credits in packs, paid in USDT on the TRON network (TRC-20).| Pack | Credits | Price | Per credit | Good for |
|---|---|---|---|---|
| Pro (most popular) | 100 | $30 | $0.30 | ≈ 33 new projects or ≈ 50 edits |
| Ultra | 1,000 | $270 | $0.27 | ≈ 333 new projects — 10% off the Pro rate |
Buy credits
Pay in USDT (TRC-20)
Send the shown amount from any TRON wallet to the checkout address. The payment is identified by its unique amount — no memo or tag is needed.
| State | What you see | What you do |
|---|---|---|
| Pending | Checkout waiting for the transfer | Send the exact USDT amount shown |
| Confirming | Transfer seen, waiting for on-chain confirmation | Wait — TRON confirmation is usually quick |
| Credited | Credits appear in your balance | Start building |
Mythos uses non-custodial crypto checkout — you pay on-chain in USDT/USDC on TRC-20. There is no
card subscription to cancel; you simply buy more credits when you run low.
If a build fails, you are not charged
Every generation ends in exactly one of two outcomes — a delivered result, or a clean refund. You are never charged for a build that did not deliver.| Outcome | What you see | What happens to your credits |
|---|---|---|
| Delivered | A result card with a preview | Spent (3 for a build, 2 for an edit) |
| Failed / interrupted | A short message that something went wrong | Refunded in full — re-prompt at no cost |
Referrals
Invite someone with your referral link. When a person you referred makes their first top-up of $30 or more, you receive 50 credits — one reward per referred person.FAQ
