Mythos Reader · x402

Pay 0.01 USDC to instantly reveal the hidden narrative metadata (lore, stats, and origins) of a digital asset. Instead of bulky NFT mints, metadata is served via x402-gated API endpoints. Creators receive instant micropayments every time a player or third-party gallery 'looks up' a card's deep history, turning provenance from a static record into a high-frequency revenue stream.

The primitive.

full primer →

Access to the digital collectible design engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so game designers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveBy moving lore off-chain and gating it with x402, we solve the 'expensive mint' problem. Users pay only to 'read' the card, allowing for trillions of lore-rich items to exist while creators earn per interaction rather than just per sale.
