  title: Wundership MPP Inference Gateway API
  version: '2026-07-15'
  description: Public OpenAPI surface for Wundership machine-paid agent requests. Unpaid requests return HTTP 402 Payment Required.
  guidance: Use POST /v1/plan with a JSON body containing a prompt or idea to buy a structured Wundership software plan. Discovery endpoints are public. Paid operations declare x-payment-info and return HTTP 402 Payment Required until payment is authorized. After payment, retry the same request with the payment authorization or verified proxy headers described by the payment challenge.
