CharGen Billing API
Programmatic wallet top-ups. OPTIONAL - most developers top up in the portal at char-gen.com/developers; this exists so your own systems can produce a payment link (e.g. from a low-balance alert).

info:
title: CharGen Partner Billing API
description: 'Wholesale generation API for images, video, audio, 3D models and structured D&D entities. Authenticate every call with `Authorization: Bearer YOUR_API_KEY` (keys are minted in the developer portal at char-gen.com/developers). Generations are asynchronous: POST returns 202 with an id, poll GET /partner/v1/generations/{id} for status and results (renders on POST /partner/v1/generations, structured D&D entities on POST /partner/v1/entities). Billing is a prepaid USD wallet; GET /partner/v1/models lists your per-model prices.'

summary: Create a Stripe Checkout link to fund your wallet
description: Returns a Stripe Checkout URL for the given amount ($10 to $100,000). No money moves on this call - a human opens the URL in a browser and pays there; the wallet is credited automatically once Stripe confirms the payment (usually seconds). Requires the `billing` scope.
