Translation runs inside Crowdin projects and connected engines, so it is not a stateless per-character translation API. No Retry-After guidance, idempotency keys or SLA were found in the reviewed documentation.\n\n**LibreTranslate.** Open source under AGPL-3.0, self-hosted with no text leaving your network. No status page, SLA or terms of service for the hosted API.\n\n## Before you call either\n\n### Crowdin\n\n1. Send `Authorization: Bearer \u003ctoken\u003e` to `https://api.crowdin.com/api/v2`. Crowdin Enterprise uses `https://\u003corganization_domain\u003e.api.crowdin.com/api/v2`\n2. Use the MCP V2 endpoint `https://mcp.crowdin.com/v2/mcp` and set `crowdin-tool-sets`, because the server loads all 33 tool sets by default\n3. Set `crowdin-read-only: true` on the MCP connection for exploration. It exposes only list and get tools\n4. Keep to 20 concurrent requests an account across all tokens, and add your own backoff on 429\n5. Upload a file to `/storages` first, then pass the `storageId` to the add-file call. Builds, exports and reports are asynchronous and need a status poll\n6. `/mts/{mtId}/translations` takes at most 100 strings a call and needs the `mt` scope and a configured engine\n\n### LibreTranslate\n\n1. Split text into calls of 2,000 characters or fewer on the hosted service\n2. Pace to about 20 calls a minute on Pro, since repeated 429s turn into a 403 ban\n3. Pass `source=auto` to detect and translate in one call\n4. Set `format=html` for markup\n5. Read /spec on the server you call, since self-hosted limits and options differ from the hosted ones\n\n## Questions\n\n### Which is better for AI agents, Crowdin or LibreTranslate?\n\nCrowdin scores 69.6 (B) on agent readiness against LibreTranslate's 49.8 (D), and leads in 6 of 7 scored categories.
