  notes: >-
    Filament uses wallet-signature authentication rather than API keys or OAuth.
    There are no securitySchemes because the API is not described by an OpenAPI
    document; the scheme below is captured from the published API documentation.
schemes:
- name: WalletSignature
  type: signature
  algorithm: EIP-191 personal_sign (ethers.js Wallet.signMessage)
  library: ethers.js v5.7.2
  description: >-
    Every mutating request (place/cancel order, update isolated margin) carries a
    `signature` field produced by signing the order's `orderId` with the trader's
    private key: `signer.signMessage(orderId)`. The `account` field must be the
    signer's wallet address in lowercase. Order ids are generated with
    `nanoid().toLowerCase()`. There is no bearer token, API key header, or
    session — authenticity is proven per-order by the signature.
