GEN Asset Libraries API

openapi: 3.2.0
info:
  title: Auto Content Engine Asset Libraries API
  description: 'The GEN Auto Content Engine API takes a raw idea all the way to a published video — agent setup, idea research, vidsheet production, layer composition, render, and publish.


    ## The 5-step journey


    Every operation belongs to one phase of a 5-step user journey. Each operation carries an `x-phase` extension you can filter on:


    | Phase | Meaning |

    |-------|---------|

    | `setup` | Step 1 — Set Up Your Agent (identity, voice, personality, API keys, workspaces) |

    | `ideas` | Step 2 — Generate Content Ideas (trending data, research, refinement, preferences) |

    | `convert` | Step 3 — Convert Idea to Vidsheet (clone template or build custom engine) |

    | `edit` | Step 4 — Edit & Generate (cells, layers, creation cards, trigger + poll) |

    | `export` | Step 5 — Export & Publish (render, download, publish to social) |

    ## Authentication


    All endpoints require authentication via one of:


    - **API Key** (recommended): Pass your API key in the `X-API-Key` header. Create keys on the agent''s API page in the GEN dashboard.

    - **JWT**: Pass a Bearer JWT in the `Authorization: Bearer ` header.


    ## Base URLs


    ```

    https://api.gen.pro/v1 — agent setup, vidsheets, generations, renders, publishing

    https://agent.gen.pro/v1 — content ideas, research, conversations, chat

    https://agent-core.gen.pro/v1 — agent core (brand profile, watchlists, scheduled tasks)

    https://python.gen.pro — social publishing integration (connect, schedule, remove posts)

    ```


    Each operation carries its own `servers` entry, so a generated client or a

    hand-written call goes to the backend that serves the route.


    ## Credits


    All `/v1/vidsheet/` endpoints require an active GEN credit balance.

    If your organization has no usable credits, requests return `422` with error code `usable_gen_credit_required`.


    Credits can be funded with x402 by calling `POST /v1/x402_credit_purchase`

    with `workspace_id` plus `amount_usd` or `credits`. If `network` is omitted,

    GEN returns every configured payment option in `payment_methods` and

    `payment_required.accepts`; show the Sui, Solana, and Base options to the

    user or calling agent and sign one selected accept entry. Workspace funding

    wallets are backend settlement infrastructure; the user-facing payment

    choices are the returned payment methods.'
