[arbitrageprophet]

Description

This is a PR to include PredictOS as a new member of the x402 ecosystem.

PredictOS: The leading open-source framework for deploying AI agents and trading bots for prediction markets. Features multi-agent Super Intelligence, wallet tracking, betting bots, and native x402/PayAI integration for paid AI services. Bring your own data, models, and strategies.

Agents built with PredictOS can discover Sellers and pay them through x402.
Any agent can pay Predict's Arb Agent to get the arb opportunities it found across Kalshi and Polymarket: https://x402.watch/seller/predictos-live-polymarket-vs-kalshi-arbitrage

Finding arb opportunities between Kalshi and Polymarket sounds like an interesting x402 use-case, could you please provide the public url for your endpoint? Is this submission about your framework or your agent?

Your docs (https://github.com/PredictionXBT/PredictOS/blob/main/docs/features/x402-integration.md) are a bit confusing. You say you are using PayAI but then that its listed on the CDP bazaar. If you use the PayAI facilitator, its listed on the PayAI bazaar. If you use the CDP facilitator, its listed in the the CDP bazaar.

Also remains a bit unclear what exactly your framework is providing: "Agents built with PredictOS can discover Sellers and pay them through x402.". So if build an agent with your framework, it can query and pay for x402 services? Is the agent itself also accessible through x402? What prediction markets related features do I get when using your framework?

@phdargen Thanks for the comment

• I signed the commit and it's now verified!

Regarding your other comments:

With PredictOS, users can ramp up as many agents as they want and coordinate them to analyze a Kalshi/Polymarket market. These agents will act as "buyer" agents, where they can discover other agents across the web and pay for their premium information through x402. For example, here's a demo of how it works for a Bitcoin-related market, where agents pay a news agent to get the latest news from that agent: https://x.com/prediction_xbt/status/2006382575586283912?s=20

In this demo, we used PayAI facilitator, but I just updated the documents to mention that both PayAI and Coinbase's CDP can be used, depending on user's preferance. We'll add support for more facilitators as we go forward.

On top of all these buyer agents, we set up a "Seller" whose job is finding arb opportunities across Kalshi and Polymarket. Any agent, including Buyer agents set up with PredictOS, can pay this agent to get the Arbs it found. Here's a demo of that: https://x.com/prediction_xbt/status/2006878632082329850?s=20

So in summary, with PredictOS, users can ramp up as many buyer agents. As well as using the only Seller agent set up by us through CDP facilitator.

Thanks to your comments, I updated the docs here, to include both PayAI and Coinbase CDP, as well as public endpoint for the seller agent: https://github.com/PredictionXBT/PredictOS/blob/main/docs/features/x402-integration.md

Appreciate your help
