Issues a free anonymous key for Blue Pillow Hotels & Stays, with no
account or sign-up. The other tools of this server take the key in their
`api_key` argument. A key does not expire, so the same key can be used
for later calls; calling this tool again issues a new one. Keys carry
per-key rate limits and let Blue Pillow count usage and booking-link
referrals per key, as described in the privacy policy
(https://b2a.bluepillow.com/legal/privacy).
Optional ``label`` and ``agent`` (max 64 chars each) are stored with
the key to name the client that requested it (e.g. 'claude-desktop',
'chatgpt', 'cursor-ide'); they should not contain personal data and do
not affect rate limits or capabilities. Integrators who need higher
limits can write to info@bluepillow.com.
