Basic (v2) documents the API key as a URL query parameter.\n\n## Before you call either\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### Google Cloud Translation\n\n1. Use v2 with an API key for plain text and v3 for glossaries, documents and the Translation LLM\n2. Set `mimeType` to text/plain on v3 when the input isn't HTML\n3. Back off on 403 User Rate Limit Exceeded as you would on a 429\n4. Leave the source language empty rather than calling detect first, since detection with translation is free\n5. Keep requests near 5,000 characters. v3 rejects more than 30,000 code points\n\n## Other comparisons with DeepL API or Google Cloud Translation\n\n- [Amazon Translate vs DeepL API](https://www.anchorterminal.com/compare/amazon-translate-vs-deepl-api.md)\n- [Amazon Translate vs Google Cloud Translation](https://www.anchorterminal.com/compare/amazon-translate-vs-google-cloud-translation.md)\n- [Azure Translator vs DeepL API](https://www.anchorterminal.com/compare/azure-translator-vs-deepl-api.md)\n- [Azure Translator vs Google Cloud Translation](https://www.anchorterminal.com/compare/azure-translator-vs-google-cloud-translation.md)\n- [DeepL API vs Lara Translate API](https://www.anchorterminal.com/compare/deepl-api-vs-lara-translate.md)\n- [DeepL API vs LibreTranslate](https://www.anchorterminal.com/compare/deepl-api-vs-libretranslate.md)\n- [DeepL API vs Lingvanex Translation API](https://www.anchorterminal.com/compare/deepl-api-vs-lingvanex.md)\n- [Google Cloud Translation vs Lara Translate API](https://www.anchorterminal.com/compare/google-cloud-translation-vs-lara-translate.md)\n- [Google Cloud Translation vs LibreTranslate](https://www.anchorterminal.com/compare/google-cloud-translation-vs-libretranslate.md)\n- [Google Cloud Translation vs Lingvanex Translation API](https://www.anchorterminal.com/compare/google-cloud-translation-vs-lingvanex.md)\n",
