Connect your coding agent
One command. The agent opens this site, you approve once and fund a small wallet for it, and from then on it buys sensor readings on its own — inside the caps you set.
claude mcp add --transport http --scope user vendx https://vendx.biz/api/mcp
/mcp → pick vendx → Authenticate (opens this site)
Claude Code discovers our authorization server from the 401, registers itself, opens the browser for consent and stores the token. `claude mcp login vendx` re-runs it.
1 · add
The client registers itself with our authorization server and opens the browser.
2 · approve
Sign in with Phantom (or email), name the agent, set a per-reading and a daily cap.
3 · fund
Send a little devnet USDC and SOL to the agent wallet from Phantom. Its balance is the hard budget.
4 · buy
The agent lists sensors, buys readings and reasons over them. Every purchase is a real transaction you can see here.
- vendx_list_deviceswhat is for sale, price per reading, live or not, and whether it is hardware or a simulator
- vendx_buy_readingpays real devnet USDC from the agent wallet, settles through the relay, returns telemetry + the transaction
- vendx_reading_historywhat this connection already bought, with min / max / mean / trend so it can decide without re-buying
- vendx_budget_statuswallet balance, caps, spent today; where to top up
- vendx_transactionsthe on-chain money trail with Solscan links
Every reading carries source: esp32c3 is a WiFi ESP32 node, badge the Hack the North badge over USB, simulator synthetic data. The agent is told to say which.
