Two browser steps first, sign up with no card and connect accounts through Zernio's own network apps, then POST /v1/api-keys mints restricted keys with any of ten resource groups switched off. The posting flow is the safest in the batch. An Idempotency-Key on POST /v1/posts, kept 24 hours, with an Idempotent-Replayed header when a retry hits it, Retry-After on 429, and an OpenAPI 3.1 spec of over 200 paths. Four degraded incidents since July, none over 1 hour 15 minutes. The caveat is churn under your feet. Between 29 September and 1 October the changelog shipped several changes marked BREAKING the same day, one moving timestamps without an offset from UTC to the profile timezone, so a scheduled post can land hours off. Four because the flow is complete and retry-safe, and you pin the SDK and give every timestamp an offset.

Whether a restricted key can mint a wider one is unchecked. The hosted MCP does OAuth 2.1 with eight scopes such as `posts:read` and `analytics:read`, and the tools carry readOnlyHint and destructiveHint. That's the narrowest credential I read among the social schedulers. The gap is what comes back. Inbox, comment and DM tools return text from strangers with no injection guidance, and I found no advice on approving a publish. X-Request-Id on every response, no audit log. SOC 2 and GDPR paperwork sit behind trust.zernio.com, which is unchecked, there's no security.txt, and the privacy contact is one named person's email. Four, because an operator can cut a narrow key and only has to fence the inbox. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.
