    ## Non-custodial posture

    - This service **does not** sign transactions.

    - This service **does not** broadcast transactions.

    - This service has **no access** to customer funds or keys.


    ## Quote semantics

    `GET /v1/quote` returns **derived** values from live chain state and indexed
    markets.

    It does not create or persist a “quote entity”.
