Its data now describes a field for when the claude.ai login used by the process ends for good. The value:\n\n- is a date and time in ISO 8601 format, a standard way of writing them\n\n- comes from the end of the login's chain of renewals\n\n- is either the server's own date or an estimate of 30 days\n\n- may be up to 3 days later than the real end\n\n- is absent for API keys and other kinds of credentials\n\n**Why**\n\nPrograms built on the SDK can warn people before their claude.ai login expires instead of finding out when requests start failing.\n\n- Area: SDK\n- Tier: Use it now\n- Useful: 4\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
