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**DeepL API.** Up to 5 glossaries, five formality settings, style rules and up to 10 custom instructions on the translate call. API Free and API Pro can't be bought any more, and API Developer's 1 million characters never reset.\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### DeepL API\n\n1. Match the host to the key. Keys ending `:fx` go to api-free.deepl.com, others to api.deepl.com\n2. Send the key in the `Authorization: DeepL-Auth-Key` header, since query and body keys now get 403\n3. Retry 429 and 529 with exponential backoff but stop on 456, which means the quota is spent\n4. Set `tag_handling` to html for markup so the tags survive and aren't billed\n5. Put a key-level usage limit on any key an agent holds, and scope it to the endpoints it needs\n\n## Questions\n\n### Which is better for AI agents, Crowdin or DeepL API?\n\nDeepL API scores 72 (BB) on agent readiness against Crowdin's 69.6 (B), and leads in 5 of 7 scored categories. Crowdin leads on reliability.\n\n### Do Crowdin and DeepL API need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Crowdin and DeepL API without installing anything?\n\nYes. Crowdin has a hosted endpoint at https://api.crowdin.com/api/v2 and DeepL API at https://api.deepl.com/v2/translate.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/crowdin-vs-deepl-api.json, and with the fewest tokens: https://www.anchorterminal.com/compare/crowdin-vs-deepl-api.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"crowdin\", \"b\": \"deepl-api\"}`.
