How it works

One x402 charge unlocks a full deep-research dossier.

Canteen Insight is built for the Canteen × Circle hackathon. It demonstrates an end-to-end onchain micro-payment flow on Arc Testnet, coupled with multi-source AI intelligence and a real path to trade execution on Polymarket.

Step 1

Connect wallet

Plug in any wallet. We support Arc Testnet for payments and Polygon for trading.

Step 2

Pay 0.01 USDC

An x402 challenge is signed onchain by your wallet, recorded by the PaymentVault.

Step 3

AI report streams

TikHub aggregates evidence across TikTok / X / YouTube / Google News in parallel; DeepSeek reasons over them and ships a calibrated YES/NO verdict.

Step 4

Trade on Polymarket V2

We auto-detect your funding wallet (Safe / Proxy / Deposit), derive an API key with one EIP-712 signature, then place a $1-min FAK market order via clob-client-v2.
