## OpenAPI

````yaml /openapi.json get /v1/openapi.json
openapi: 3.1.0
info:
  title: paperplane API
  version: 1.0.0
  summary: Send real physical mail from code.
  description: >-
    Upload a PDF or paste text; we print it and hand it to USPS the next
    business day. No account required — pay per letter with a Stripe link or a
    prepaid credit code, and use `sandbox: true` to exercise the whole flow for
    free.


    Every failure returns the same envelope: `status`, a stable machine-readable
    `code`, a human `reason`, and a `next` array of concrete recovery steps.


    This document is generated from the same zod schemas the server validates
    with, so it cannot describe an endpoint that does not exist.
