Product Engineer InternBuilt zScreen's MCP server over the on-chain wallet-screening API — spec, hosting, test suite, deployed live over HTTP — with agent-readable reference docs and a PostHog-instrumented funnel, and added pay-per-screen billing on the x402 protocol that takes $0.50 from the caller's wallet when no API key or allowance exists. On ZAPS, fixed wallet-reputation flows including a stored zScore that could freeze permanently and live-vs-stale score mismatches, added delegated zScore minting for wallets a user won't connect, and reworked the Hyperliquid demand worker to aggregate sub-accounts by profit.
