Quick Install
Automated & IDE SetupCopy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.
One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.
Manual Client & Custom JSON ConfigExpand JSON ▾
No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for Blixtworks, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.

Documentation Overview
img-categorize / agent-hustle
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
| Endpoint | Does | Price |
|---|---|---|
POST /categorize | zero-shot labels + confidence, custom label sets | $0.02 |
POST /caption | one-sentence image description | $0.02 |
POST /ocr | printed-text extraction (English) | $0.03 |

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 (viemverifyMessage) — no shared-secret setup, no hijackable upstream. - Front door offline-safe: no upstream → 503 → buyer not charged.
Run the home side
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.
