0-wAIst

0-wAIst is an AI subscription de-reseller router: a buyer submits a prompt, Quick Buy or Router Agent selects a compatible proxy seller, and the service executes the same order workflow while keeping raw prompt content out of public artifacts. The runnable demo routes real OpenAI-backed inference through ProofRouter, writes hash-only Hedera Testnet audit messages, exposes HashScan evidence, publishes seller offers through a ProxyRegistry, and shows HTS INF / ProofEscrow readiness for funded orders. The project focuses on making AI subscription resale auditable without leaking prompts: public chain data contains hashes and receipts, while local traces and prompt history are redacted/encrypted. Full trusted CRE/zkTLS settlement is treated as a gated next step, not claimed as complete in the demo.

0-wAIst is built as a TypeScript pnpm monorepo. The React/Vite app calls the ProofRouter service, and both Quick Buy and Router Agent go through the same executeInferenceOrder workflow; the difference is only seller selection policy. Shared packages own schemas, hashing/redaction/encryption, and Hedera helpers. The Hedera layer uses HCS for hash-only audit messages, HFS for a market manifest, HTS INF for the intended settlement asset, and Solidity contracts for ProxyRegistry, ProofEscrow, and VerifierRegistry. The proofrouter-mcp service exposes the router through a real MCP stdio server and HTTP API, while seller-node exposes the /x402 and OpenAI-compatible seller proxy path. The notable build constraint was keeping prompt text out of public artifacts: chain/HCS data only gets hashes, local traces are redacted, and prompt-history summaries are encrypted locally. The demo also includes health checks that distinguish runnable Hedera/OpenAI evidence from the still-gated trusted CRE/zkTLS settlement path instead of pretending the verifier is complete.
