# Get market config

> Returns the current round duration and epoch anchor.



## OpenAPI

````yaml /_generated/openapi.yaml get /v1/market/config
openapi: 3.1.0
info:
  title: Joyride Exchange REST API
  version: 1.0.0
  description: >
    REST API for the Joyride 0DTE Options Exchange.


    ## Authentication


    **Public endpoints** (`/health`, `/v1/market/*`, `/v1/spot/*`,
    `/v1/oracle/*`) require no authentication.


    **Competition prize claims** (`/v1/competition/claim`) are
    self-authenticated

    by a Solana ed25519 signature over the wallet, Discord handle, and payout

    destination in the request body. No JWT is required for that endpoint.


    **Account endpoints** (`/v1/account/*`, `/v1/orders/*`,
    `/v1/social/profile`, `/v1/social/avatar`) require JWT authentication via
    one of:

    1. `Authorization: Bearer <jwt>` header (primary — native clients)

    2. `Cookie: joyride_session=<jwt>` (web clients, set automatically by
    `/v1/auth/verify`)


    **Withdrawal endpoints** (`/withdrawals`, `/v1/withdrawals`) require the

    `Authorization: Bearer <jwt>` header. A session cookie alone is not
    accepted.


    Obtain a JWT by completing the SIWS (Sign In With Solana) flow:

    1. `POST /v1/auth/nonce` with your wallet address to get a nonce

    2. Sign the canonical SIWS message with your wallet

    3. `POST /v1/auth/verify` with wallet, signature, and message to receive a
    JWT


    **Mutating admin endpoints** require a bearer token:

    ```

    Authorization: Bearer <ADMIN_TOKEN>

    ```


    ## Data Conventions


    - **Prices**: Integer values in USDC micros (1 USDC = 1,000,000 micros).
      Example: `1500000` = $1.50
    - **Sizes**: Integer values in millicontracts (1 contract = 1000
    millicontracts).
      Example: `1000` = 1 contract
    - **Balances**: USDC micros. Example: `10_000_000_000` = $10,000

    - **Timestamps**: Unix microseconds (µs since epoch)

    - **Instrument IDs**: Format `{ASSET}_USDC-{DMMMYY}-{STRIKE}-{C|P}`.
      Example: `SOL_USDC-28FEB26-150-C`

    ## Trading


    **Trading is WebSocket-only.** The HTTP API has no order placement
    endpoints.

    See the AsyncAPI spec for WebSocket trading methods.

        Constant across the deployment — surfaced on `/v1/market/config` so
        agents can

        resolve units from a single endpoint instead of cross-referencing docs.
