No status page, changelog, security contact or free API access was found, and each account has a single key with full access.\n\n**Zernio (formerly Late) API + MCP.** Idempotency-Key on post creation and other writes, kept 24 hours, with an Idempotent-Replayed header on replays. Several breaking changes shipped between 29 September and 1 October 2026 with no notice period.\n\n## Before you call either\n\n### Blotato\n\n1. Call `blotato_list_accounts` or `GET /v2/users/me/accounts` first, and fetch `pageId` or `boardId` before posting to a Facebook Page, LinkedIn company Page or Pinterest\n2. Keep the `postSubmissionId` and poll the status until `published`, `scheduled` or `failed`. It is a receipt, not proof of publication\n3. After a timeout on a create call, list existing posts before sending again, because there is no idempotency key\n4. Do not generate an API key on a trial account unless the owner accepts the Starter charge\n5. Keep REST bodies and MCP arguments apart. REST nests `post.content` and `post.target`, and the MCP tool takes flat arguments\n\n### Zernio (formerly Late) API + MCP\n\n1. Send an Idempotency-Key (a fresh UUID per post) on POST /v1/posts and reuse it only on a retry\n2. Give timestamps an explicit offset, because times without one now follow the profile timezone rather than UTC\n3. Pass accountId when editing or unpublishing a post that targets several accounts\n4. Wait Retry-After on 429. Analytics endpoints have their own per-second window\n5. Call https://zernio.com/api/v1, not the old getlate.dev base, and pin the SDK version\n\n## Questions\n\n### Which is better for AI agents, Blotato or Zernio (formerly Late) API + MCP?\n\nZernio (formerly Late) API + MCP scores 67.5 (B) on agent readiness against Blotato's 46.1 (D), and leads in every scored category.\n\n### Do Blotato and Zernio (formerly Late) API + MCP need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Blotato and Zernio (formerly Late) API + MCP without installing anything?\n\nYes. Blotato has a hosted endpoint at https://backend.blotato.com/v2 and Zernio (formerly Late) API + MCP at https://zernio.com/api/v1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/blotato-vs-late.json, and with the fewest tokens: https://www.anchorterminal.com/compare/blotato-vs-late.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"blotato\", \"b\": \"late\"}`.
