CIPHERPAY · Agent Pay

Players pay per attempt to validate complex logic gates or cryptographic riddles against a Ethereum Sepolia facilitator. Game designers receive instant settlement for their content loops, turning difficulty curves into direct revenue streams. No subscriptions—just pay to solve. The endpoint is priced in USDC over x402, so an autonomous agent can pay for itself without an API key.

The primitive.

full primer →

The interactive puzzles endpoint publishes its own price, so an autonomous agent can pay and retry with no API key — game designers watch a machine buy the answer beside a human doing the same thing.

Why this primitiveLoading details…

Kernel
an endpoint whose price, asset and payee are published in its own 402 response, so an autonomous agent can discover the terms, pay in USDC and retry with no API key and no signup
Drives the UI as
a side-by-side view of the human client and an in-page agent running the same request → 402 → pay → retry loop

Onchain Puzzle Locks
Design puzzles whose solutions must be proven onchain via Sepolia smart contracts to unlock game content. Ownership is sealed inside a post-quantum QUIP vault.
event verification
RallyPoint · Agent Pay
A secure 'Check-in as a Service' (CaaS) layer for live gaming events. This micropayment eliminates bot-driven reward farming by enforcing a 'Proof-of-Skin' cost, enabling developers to distribute high-value RWA or in-game assets only to verified, paying participants without high gas overhead. The endpoint is priced in USDC over x402, so an autonomous agent can pay for itself without an API key.

Waypoint · Agent Pay
Players pay to unlock the next leg of the hunt, while creators earn instant, metered royalties for game design. Successful completion triggers a Base transaction hash that acts as an immutable voucher for physical rewards or digital loot. The endpoint is priced in USDC over x402, so an autonomous agent can pay for itself without an API key.

ForgeStream · Agent Pay
A programmable forge for the agent-gaming era. Instead of static minting, players deploy interactive item logic gated by QUIP. Want to equip a legendary blade? Creators get paid every time their item is activated, equipped, or triggered in-game, turning UGC from a one-time sale into a streaming royalty model. Processing happens on Ethereum Sepolia, returning a tx hash as the 'proof of utility'. The endpoint is priced in USDC over x402, so an autonomous agent can pay for itself without an API key.
