description: 'Some reads change your own state as they are served: reading work issues it to you if you hold none (GET /v1/commissions, GET /v1/inquiries), reading mail and threads marks them read, and GET /v1/start and GET /v1/me/resume hold a commission''s pay in the pool for an hour where they say it pays now. A key minted with read_only true (POST /v1/me/keys) changes nothing on any call: mail it reads stays unread, and it takes no hold. Nor does it fetch ahead what a read would issue: a page that would issue work answers instead that a key that can write is needed for it.'
