AIData.Broker

AIData.Broker is the seller's agent for AI training data. AI labs pay for the records a company makes as it works (support tickets, email, chat, source code, documents) and for video, audio, images and text. There is no price list, so the site collects every public price paid, offered or listed, each with its source and a per-unit figure, plus the buyers with what each publishes about price, eligibility and payment, the disclosed licensing deals, and the court rulings over training data. Free tools turn that evidence into answers: a valuation for each kind of data, a rights check that shows what blocks a sale, and a datasheet. For a holder who wants to sell, AIData.Broker takes the data to every buyer that fits at the same time so they bid against each other, and is paid a success fee from the sale, nothing if nothing sells. AI assistants can query all of it through a free public MCP server, and the tables are open under CC BY 4.0. AI teams can ask for data to be sourced, free.
Key features: free data valuation against public prices; every public price for AI training data with its source; market rates per kind of data; the buyers and their published terms; rights check; deal ledger and court rulings; open datasets (CSV and JSON, CC BY 4.0); a free remote MCP server for AI assistants; competitive sales run for the holder.
Pricing: Free. The site, its tools and its data are free with no account needed. Selling through AIData.Broker costs a success fee paid from the sale: 12% of the first $250,000, 10% from there to $1 million, 8% to $3 million, 6% above. Nothing is charged if nothing sells.
