- url https://heyzine.com
- free tier: Free Basic: 5 flipbooks, unlimited pages, 1 GB storage, 1 user, no watermark, API access included. | unit: GB | metered on: stored-bytes | read on: 2026-10-21 | source: [1]

- identity: institution
- interface: rest
- limits note: 1 GB total disk per account; 5 flipbooks on free; PDF is converted to page assets rather than stored byte-for-byte; over-quota accounts get 'old flipbooks auto removal'.
- interface detail: rest
- tooling: Real documented API + MCP server: create/list/delete flipbooks, access lists, embed codes, webhooks; API key via 'Authorization: Bearer'. Third-party python libs exist but nothing first-party for bulk sync.
- composes with: 1 GB/account x unlimited free accounts; the API means it is automatable, but 1 GB units mean 1 TiB == 1,024 accounts and 10 TiB == 10,240. Only interesting as a serving front, not as bulk storage.
- reliability: Over-quota accounts are subject to automatic deletion of old flipbooks, and free accounts hold only 5 publications.
- notes: the same as the free tier
- extras:
  - dead_end.failure_class: quota
  - dead_end.why: Free Basic: 5 flipbooks, unlimited pages, 1 GB storage, 1 user, no watermark, API access included.

  - [3] 2026-10-21: API: create/list/delete flipbooks, 'Authorization: Bearer API_KEY'
