## OpenAPI

````yaml /openapi.yaml get /custody/get-deposit-addresses
openapi: 3.1.0
info:
  title: Symbiosis API
  description: >-
    The Symbiosis REST API.


    ## Authentication


    Endpoints accept one of two credentials:


    - **Session token** — `Authorization: Bearer <token>`, from `POST
    /auth/login`.

    - **API key (HMAC)** — three headers on every request:
      - `APIKEY`: the API key id, from `POST /auth/api-keys`.
      - `X-Hmac-Timestamp`: current Unix time in milliseconds.
      - `X-Hmac-Signature`: Base64-encoded HMAC-SHA256 of
        `timestamp_ms "\n" METHOD "\n" PATH_AND_QUERY "\n" BODY`, keyed with the API key
        secret. `PATH_AND_QUERY` is the full request target including the query string.

    ## Wire formats


    Token amounts (`U256`) serialize in responses as 0x-prefixed hex strings;
    requests accept decimal strings, 0x-prefixed hex strings, or JSON numbers.
    Asset ids and addresses are 0x-prefixed hex strings. Prices are integers
    scaled by 1e6.
