Mythos Query · x402

A high-frequency indexing service where metadata retrieval is metered. Developers and game engines pay 0.01 USDC per HTS transfer signed request to instantly resolve a Lore Token's IPFS manifest. Instead of bulk API subscriptions, pay only for the specific narrative assets your players trigger in-game. Settlement happens instantly on Hedera.

The primitive.

full primer →

Access to the metadata indexing 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 primitiveLore indexing is often a bottleneck in decentralized gaming. By moving from a subscription model to a pay-per-resolution (x402) model, small developers can scale from 1 to 1,000,000 items without upfront costs, while the indexer earns immediate, liquid USDC for every read operation.
