Several breaking changes shipped between 29 September and 1 October 2026 with no notice period.\n\n## Before you call either\n\n### bundle.social\n\n1. Send the key in the `x-api-key` header to `https://api.bundle.social/api/v1`. A missing key returns 401 and a bad key 403\n2. Pass `teamId` on most calls. Set `BUNDLESOCIAL_TEAM_ID` for the MCP server or CLI when the organisation has more than one team\n3. Set a `referenceKey` on each post and look it up with the reference-key endpoint before retrying a create, because there is no idempotency key\n4. Check `GET /api/v1/organization/usage/daily-limits` before bulk scheduling. Failed and deleted posts still count against the monthly quota\n5. A person must complete each network's OAuth consent in a browser. Keep prepaid credit for X, where a post costs $0.015 or $0.20 with a link\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, bundle.social or Zernio (formerly Late) API + MCP?\n\nZernio (formerly Late) API + MCP scores 67.5 (B) on agent readiness against bundle.social's 60.1 (C), and leads in 5 of 7 scored categories. bundle.social leads on transparency \u0026 trust.\n\n### Do bundle.social and Zernio (formerly Late) API + MCP need an API key?\n\nbundle.social needs an API key. Zernio (formerly Late) API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call bundle.social and Zernio (formerly Late) API + MCP without installing anything?\n\nYes. bundle.social has a hosted endpoint at https://api.bundle.social/api/v1 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/bundle-social-vs-late.json, and with the fewest tokens: https://www.anchorterminal.com/compare/bundle-social-vs-late.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"bundle-social\", \"b\": \"late\"}`.
