    # Solya API


    Solya is a fashion retail inventory management platform for buyers and
    merchandisers.

    This API exposes all capabilities needed to manage the inventory lifecycle:
    catalog

    browsing, risk detection, plan creation (Restock / Markdown / Rebalance),
    analytics

    queries, and data-platform operations.


    ## Authentication


    Three authentication schemes are supported:


    | Scheme | Header | Use case |

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

    | **BearerAuth** | `Authorization: Bearer <nextauth-token>` | Human users
    via the Solya web app (NextAuth session) |

    | **InternalBearerAuth** | `Authorization: Bearer <static-token>` | Internal
    jobs and cron tasks (static token per service) |

    | **ServiceAccountToken** | `Authorization: Bearer solya_sa_*` | LLM agents
    and programmatic clients (opaque token created via Settings) |


    All endpoints except `GET /api/health` require one of the above.

    See [Agent authentication guide](/docs/api/AGENT_AUTH.md) for the Service
    Account token flow.


    ## Response format


    Every endpoint returns an `ActionResponse<T>` envelope:


    **Success:**

    ```json

    { "success": true, "data": { ... } }

    ```


    **Error:**

    ```json

    { "success": false, "errorCode": "PLAN_NOT_FOUND", "error": "Human-readable
    message" }

    ```


    The `errorCode` is a stable machine-readable string (see common error codes
    below).

    The `error` field is for human display only and may change between versions.


    ## Pagination


    List endpoints accept `page` (1-indexed, default 1) and `pageSize` (default
    20, max 100).

    Responses include a `total` field with the total number of matching records.


    ```

    GET /api/shops?page=2&pageSize=50

    → { "success": true, "data": { "data": [...], "total": 120, "page": 2,
    "pageSize": 50 } }

    ```


    ## Common error codes


    | HTTP status | errorCode | Meaning |

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

    | 401 | `UNAUTHORIZED` | Token missing, expired, or invalid |

    | 403 | `FORBIDDEN` | Token valid but lacks the required permission or scope
    |

    | 404 | `NOT_FOUND` | Requested resource does not exist |

    | 409 | `BUSINESS_RULE_VIOLATION` | Business rule blocked the operation (see
    response details) |

    | 422 | `VALIDATION_ERROR` | Input failed Zod schema validation |

    | 429 | `RATE_LIMIT_EXCEEDED` | Rate limit hit (100 req/min per token) |

    | 500 | `INTERNAL_ERROR` | Unexpected server error |


    ## Rate limiting


    Default limit: **100 requests per minute** per authentication token.

    When the limit is exceeded the API returns HTTP 429 with `errorCode:
    "RATE_LIMIT_EXCEEDED"`.

    Agents should implement exponential back-off and respect the `Retry-After`
    header when present.

    See the [Agent guide](/docs/api/AGENT_GUIDE.md) for end-to-end workflows,
    call-chaining

    patterns, and anti-patterns to avoid.

  x-ai-context: >-
    Solya is a fashion retail inventory management platform for retailers.

    Core concepts:

    - **Organization** (tenant): every endpoint is scoped by organizationId
    extracted from the token.

    - **Shop**: a physical point of sale belonging to the organization.

    - **ProductVariant**: a SKU — a product variant with size and color.

    - **Plan**: a Restock / Markdown / Rebalance grouping PlanItems to
    orchestrate inventory decisions.


    Typical agent workflow:

    1. List the organization's shops — GET /api/shops

    2. List variants at risk (stockout, overstock, slow-mover) — GET
    /api/inventory/risks

    3. Create a plan — POST /api/restock-plans, /api/markdown-plans, or
    /api/rebalance-plans

    4. Add items to the plan — POST /api/restock-plans/{planId}/items (or
    equivalent for other plan types)

    5. Validate / submit the plan via the corresponding action endpoint


    Auth: use a Service Account token (see /docs/api/AGENT_AUTH.md).

    The token is created by an org admin via Settings and has the format
    solya_sa_<43 base64url chars>.


    All responses follow the ActionResponse envelope:

    - Success: { success: true, data: T }

    - Error:   { success: false, errorCode: string, error: string }


    Use the errorCode field to drive retry logic or surface user-facing
    messages.
