No status page, SLA or terms of service for the hosted API.\n\n**Smartcat.** Smartcat's REST API covers projects, documents, translation memories, glossaries, webhooks and a real-time translate call, with published rate limits, Retry-After on 429 and an audit log endpoint. Keys are account-wide with no documented scopes, the status page lists two incidents of an hour or more in 90 days, and API access is listed only from the $60,000-a-year Anticipate plan.\n\n## Before you call either\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### Smartcat\n\n1. Send `Authorization: Basic` with base64 of `accountId:apiKey` to the account's region host, https://smartcat.ai, https://us.smartcat.ai or https://ea.smartcat.ai.\n2. On 429, wait the seconds in Retry-After before retrying. The 429 itself carries no `x-rate-limit-*` headers.\n3. Create a smart translation profile in the web app first and pass its ID as `profile` to `smartTranslation/translate`.\n4. Store each `requestUid` and look charges up later with `smartTranslation/charges`, since the translate response doesn't include the cost.\n5. Treat callbacks as hints and poll project, document or export status as a fallback, because failed deliveries are dropped after the last retry.\n\n## Questions\n\n### Which is better for AI agents, LibreTranslate or Smartcat?\n\nSmartcat scores 54.3 (C) on agent readiness against LibreTranslate's 49.9 (D), and leads in 4 of 7 scored categories. LibreTranslate leads on agent ergonomics and payments \u0026 pricing.\n\n### Do LibreTranslate and Smartcat need an API key?\n\nBoth need an API key.\n\n### Can an agent call LibreTranslate and Smartcat without installing anything?\n\nYes. LibreTranslate has a hosted endpoint at https://libretranslate.com and Smartcat at https://smartcat.ai/api/integration.\n\n### Are LibreTranslate and Smartcat open source?\n\nLibreTranslate is open source (AGPL-3.0). No open-source release is listed for Smartcat.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/libretranslate-vs-smartcat.json, and with the fewest tokens: https://www.anchorterminal.com/compare/libretranslate-vs-smartcat.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"libretranslate\", \"b\": \"smartcat\"}`.
