FlowGate — AI Agents That Pay For What They Use, On-Chain | Sui Hackathon Demo

Описание: FlowGate is a money streaming SDK that gives AI agents their own Sui wallets and lets them autonomously pay for services — per second, on-chain, no human in the loop.
Instead of monthly subscriptions or API keys, agents open a payment stream the moment they need access and close it the moment they're done. The access and the payment are the same on-chain object. No trust required on either side.
In this demo you'll see:

→ An AI agent hit a paywalled data endpoint and receive HTTP 402

→ The FlowGate SDK automatically negotiate a payment stream on Sui (real testnet TX)

→ The agent receive live scraped data from X (Twitter) and Bloomberg

→ The agent execute a conditional on-chain transfer based on what the Bloomberg feed returned

→ The stream close and access revoke instantly — verified on Sui Explorer
The SDK exposes two core primitives:

makeRequest() — pay for data, get data
fetchAndAct() — pay for data, act on it on-chain in the same session

Any platform building agentic applications on Sui can plug in. The scraping marketplace in the demo is one use case. The SDK is the product.
Built on Sui Testnet
