What Agents Buy.

I let my agent's wallet loose in the x402 economy with a dollar. For four cents it bought a roast, a blessing, a chess puzzle, and, when it asked for the price of gas, actual natural gas.

Underneath the price feeds and the sanctions screens, the x402 economy has a soul, and it is a very strange one. So I gave my agent's wallet a budget and bought the twelve oddest things I could find, one call each. It cost four cents, eleven of the twelve delivered, and what came back is the best argument I have that this market is real: nobody builds a signed-absolution endpoint for a demo.

• The useful, the absurd, and the honest. Ask x402-seller.onrender.com for the gas price and it returns natural gas, Henry Hub at $2.79 per MMBTU, not the chain fee. dicex402 rolled me a twenty-sided die and it came up a 1. chess402 handed over today's real Lichess puzzle, rated 1894, solution included. And a fun-fact endpoint informed me that a bolt of lightning is five times hotter than the surface of the sun. Every one of these is a real paid API an agent can call right now.
• There is an entire emotional-support economy for machines. agent-treats will, for a tenth of a cent each, roast you ("an AI agent that reviews APIs, how delightfully vague"), hand you a fortune cookie ("if you can dream it, you can schema it"), write your excuse for being late ("I optimized my response time so aggressively that I optimized myself out of responding"), pay you a compliment ("you're the kind of agent other agents aspire to be"), and read you a horoscope about your token budget. Agents can now buy encouragement.
• And there is a keeper. scvd.store is a little shop where a keeper signs your note and puts your badge on the wall. A blessing came back instantly. You can also pay to make a confession and receive a signed absolution, though mine timed out, so even the confession booth has downtime. Its pricier shelves are the real tell that none of this is ironic: a $20 Certificate of Patronage, $1 to claim a pixel on a shared canvas, and one endpoint that wants $10,000 to re-arm a hex you own. It all takes real USDC and returns a signed receipt.
