What it does

Answer typed questions about a state. Demo only, after explicit user confirmation of /SKILL.md terms. No production or consequential real-world decisions. Returns one answer per question: a yes probability (noul), an option and distribution (choice), or a rubric rating (score). Confidence is not proof of correctness. The response reports model and token usage; pay only against the live 402 quote for the request.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/38457.json for the price and payment options.
Pay. Call GET https://jev.agents.bakingbad.dev/v1/systemone. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans
