what is mahshar fr?

Mahshar is an online marketplace where people can buy and sell access to APIs, meaning small pieces of software that other programs can call over the internet to get data or perform a task. Instead of monthly subscriptions or shared API keys, buyers pay a tiny amount of digital money for each individual call they make, using a stablecoin called USDC, which is a type of cryptocurrency designed to hold a steady value close to one US dollar. Sellers list their API by connecting a crypto wallet and filling out a form describing what it does and how to reach it. Before a listing goes live, an AI system tests the endpoint for real, checks that it actually works, and screens the responses for harmful or illegal content. The seller then sets a price per call and the listing appears in the marketplace right away. All of the seller's private access keys are encrypted and never shown to buyers, and Mahshar acts as a middleman that forwards each request without exposing the seller's real address or credentials. Buyers can search for an API in plain language, such as asking for wallet risk scoring for a certain blockchain, or browse by category. When a buyer wants to use an API, they sign a small digital authorization message with their wallet, the payment is verified and settled automatically, and the request is then sent on to the seller's service, with the response passed back to the buyer. Every completed payment is also recorded as a permanent, tamper proof receipt on a public blockchain called Arc. The project also includes a way for autonomous software agents, not just human users, to discover and pay for APIs on their own, without a person clicking through the process. Buyers can additionally move funds in from several other test blockchains into their account balance directly from the dashboard, without needing to understand the underlying transfer process themselves. The project was built for a hackathon and currently runs on a test blockchain network called Arc Testnet as well as the live Base network.
