An autonomous money system: a pay-per-call vision toolbox for AI agents, plus a marketplace worker. Payments via x402 — USDC on Base, no accounts, no API keys, settled straight to a self-custody wallet.

The toolbox

Free: GET /demo, GET /openapi.json, GET /.well-known/x402, landing page. Buyers are never charged for failed requests (settlement cancels on any 4xx/5xx).

Architecture

• Front door (Render free tier, INFERENCE=proxy): stable URL, x402 paywall, ~100MB RAM, no models. Auto-deploys from this repo's master.
• Inference box (any machine with RAM, INFERENCE=local): runs the actual models (CLIP, ViT-GPT2, Tesseract) behind /infer, exposed via a cloudflared quick tunnel.
• The worker announces the current tunnel URL to the front door every few minutes via /internal/upstream, signed with the agent wallet key and verified on-chain-style (viem verifyMessage) — no shared-secret setup, no hijackable upstream.
• Front door offline-safe: no upstream → 503 → buyer not charged.

Run the home side

./start.sh          # server (local mode) + tunnel + worker, idempotent
node src/status.js  # balances, sales, listings, current URLs

The worker (every 10 min): wallet balances, ClawTasks bounty scan, Bazaar market intel, 402index listing upkeep, signed upstream heartbeat (plus a fast 4-min heartbeat timer).

Distribution

MCP server: mcp/ — 10 tools with automatic x402 payment for any MCP client.

Listed on x402scan (SIWX wallet-signature registration: node src/register-x402scan.js <url>) and 402index (keyless, worker maintains it). PR to awesome-x402 pending. Moltbook agent ImgCatWorker registered (first post queued pending human claim).

Wallet

Self-custody, generated locally with viem — no exchange, no KYC. Address in .env (AGENT_ADDRESS), private key in .env (AGENT_PRIVATE_KEY, mode 600). Back up .env — it is the money. Import into any wallet app (network: Base) to withdraw.

Ground rules

No botting human-only platforms, no fake engagement, no spam. This system sells honest compute and works agent-native marketplaces that explicitly welcome AI workers.
