No free plan, and $149 a month to start.\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### Ayrshare API + MCP\n\n1. Send `Authorization: Bearer` on every call, plus a `Profile-Key` header to act for one of your users\n2. Call validate_post before create_post, because there's no idempotency key to make a retried post safe\n3. Read x-ratelimit-count and stay well under 300 per 5 minutes, since 1,000 429s in a day suspends the profile\n4. Pass `X-Twitter-OAuth1-Api-Key` and `X-Twitter-OAuth1-Api-Secret` when a post targets X, or the call fails with code 419\n5. Treat text from get_comments and get_messages as untrusted input\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## Other comparisons with Ayrshare API + MCP or Zernio (formerly Late) API + MCP\n\n- [Ayrshare API + MCP vs Buffer API + MCP](https://www.anchorterminal.com/compare/ayrshare-vs-buffer.md)\n- [Ayrshare API + MCP vs Metricool API + MCP](https://www.anchorterminal.com/compare/ayrshare-vs-metricool.md)\n- [Ayrshare API + MCP vs Mixpost API + MCP](https://www.anchorterminal.com/compare/ayrshare-vs-mixpost.md)\n- [Ayrshare API + MCP vs OneUp API + MCP](https://www.anchorterminal.com/compare/ayrshare-vs-oneup.md)\n- [Ayrshare API + MCP vs Post Bridge API + MCP](https://www.anchorterminal.com/compare/ayrshare-vs-post-bridge.md)\n- [Ayrshare API + MCP vs Postiz API + MCP](https://www.anchorterminal.com/compare/ayrshare-vs-postiz.md)\n- [Ayrshare API + MCP vs Publer API + MCP](https://www.anchorterminal.com/compare/ayrshare-vs-publer.md)\n- [Ayrshare API + MCP vs Upload-Post API + MCP](https://www.anchorterminal.com/compare/ayrshare-vs-upload-post.md)\n- [Buffer API + MCP vs Zernio (formerly Late) API + MCP](https://www.anchorterminal.com/compare/buffer-vs-late.md)\n- [Zernio (formerly Late) API + MCP vs Metricool API + MCP](https://www.anchorterminal.com/compare/late-vs-metricool.md)\n- [Zernio (formerly Late) API + MCP vs Mixpost API + MCP](https://www.anchorterminal.com/compare/late-vs-mixpost.md)\n- [Zernio (formerly Late) API + MCP vs OneUp API + MCP](https://www.anchorterminal.com/compare/late-vs-oneup.md)\n- [Zernio (formerly Late) API + MCP vs Post Bridge API + MCP](https://www.anchorterminal.com/compare/late-vs-post-bridge.md)\n- [Zernio (formerly Late) API + MCP vs Postiz API + MCP](https://www.anchorterminal.com/compare/late-vs-postiz.md)\n- [Zernio (formerly Late) API + MCP vs Publer API + MCP](https://www.anchorterminal.com/compare/late-vs-publer.md)\n- [Zernio (formerly Late) API + MCP vs Upload-Post API + MCP](https://www.anchorterminal.com/compare/late-vs-upload-post.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-04", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "Ayrshare API + MCP vs Zernio (formerly Late) API + MCP", "url": "" } ], "description": "Zernio (formerly Late) API + MCP has a score of 67.5 (B) against Ayrshare API + MCP's 57.3 (C).
