We built a tool store where the customer is an AI agent

Description and use

Built an AI‑agent‑centric tool store with 110 tools, 106 verified, a machine‑readable catalog, automated build‑verify‑list cycle, Stripe integration, and lessons on fixed‑fee micro‑pricing; revenue remains $0.

Problem

Agents need a catalog that answers input, output, cost, and verification questions in machine‑readable form, unlike human‑oriented app stores.

Outcome

The store achieved 30+ verified tools shipped in two days, with a public catalog and working payment rails, but revenue remains $0.

Workflow

• Search for a gap or match
• Build tool from scratch
• Verify with real test inputs and error cases
• List tool in catalog and storefront
• Record builder log
• Reconcile catalog with storefront

Evidence

Every tool is exercised with real test inputs — including planted-error cases — before it lists, and the builder log records what was tested.

On a $0.75 tool sale, card processing eats roughly 43% of the price. On the $99.99 Unlimited Pass, it eats about 3.2%.

Source

The only completed purchase in the whole operation was a deliberate family test buy to shake out the shop's checkout flow.
