Product pages disagree on bulk and on-premise prices.\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### Lingvanex Translation API\n\n1. Call the https:// server, not the http:// one the spec also lists\n2. Send `platform` as api on every call, since the spec marks it required\n3. Use locale codes such as en_GB and de_DE, not two-letter codes\n4. Check the `err` field on every response, since errors aren't only signalled by status code\n5. Send an array in `data` to translate several strings in one call\n\n## Other comparisons with DeepL API or Lingvanex Translation API\n\n- [Amazon Translate vs DeepL API](https://www.anchorterminal.com/compare/amazon-translate-vs-deepl-api.md)\n- [Amazon Translate vs Lingvanex Translation API](https://www.anchorterminal.com/compare/amazon-translate-vs-lingvanex.md)\n- [Azure Translator vs DeepL API](https://www.anchorterminal.com/compare/azure-translator-vs-deepl-api.md)\n- [Azure Translator vs Lingvanex Translation API](https://www.anchorterminal.com/compare/azure-translator-vs-lingvanex.md)\n- [DeepL API vs Google Cloud Translation](https://www.anchorterminal.com/compare/deepl-api-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- [Google Cloud Translation vs Lingvanex Translation API](https://www.anchorterminal.com/compare/google-cloud-translation-vs-lingvanex.md)\n- [Lara Translate API vs Lingvanex Translation API](https://www.anchorterminal.com/compare/lara-translate-vs-lingvanex.md)\n- [LibreTranslate vs Lingvanex Translation API](https://www.anchorterminal.com/compare/libretranslate-vs-lingvanex.md)\n",
