    The REST B2B API uses a per-partner API key provisioned by the Despegar
    onboarding team (separate keys for test and production). The hosted MCP
    servers use OAuth 2.0 client_credentials handled server-side. Despegar also
    documents a Security API offering mutual TLS (mTLS) for B2B transactions.
