Arc Signal Desk

`Arc Signal Desk is a hackathon project built for the Agentic Economy on Arc theme. We wanted to show that agentic applications become much more powerful when every micro-action can be priced, paid for, and audited without gas overhead destroying the margin. Our product turns a research workflow into a sequence of paid actions: a user or upstream agent submits a news article, text input, or preset signal, and the system runs summary, entity extraction, and relation extraction as individually priced steps. Those outputs are then assembled into a live decision desk and a graph view so the user can inspect the result, the evidence behind it, and the payment trail that produced it. Under the hood, Arc Signal Desk combines Arc settlement, USDC-denominated pricing, and Circle nanopayment-style flows to support economically viable sub-cent transactions. We also built multiple demo paths so the project is not just a concept mockup: local mock mode for reliable demos, a real seller-side payment-gated API flow, a gateway buyer runner for true paid calls, and an Arc UsageReceipt contract that maps successful actions to on-chain evidence. This matters because the core claim of our project is not only that AI tools can be monetized, but that autonomous agents and human users can pay for exactly the next unit of useful work. That creates a more scalable economic model for APIs, machine-to-machine tools, and agentic workflows than subscriptions or gas-heavy per-call settlement.`
