Capacity top-up prices aren't public, and the terms permit training some models on customer content and prohibit benchmarking.\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### Phrase\n\n1. Exchange a Phrase Platform API token at `https://eu.phrase.com/idm/oauth/token` (or `us.phrase.com`) for a Bearer JWT, which lasts about four hours, and refresh it before it expires\n2. Send a `User-Agent` header naming your application on every Strings and TMS call. The Strings API answers 400 without one\n3. Keep Strings calls under 1,000 in five minutes and four in parallel, and read `X-Rate-Limit-Reset` and `X-Rate-Limit-Reason` on a 429\n4. Send at most six texts of 2,000 characters to `/v2/textTranslations`, with `consumerId` and `targetLang`. Term bases and translation memories work only with an AI translation agent profile\n5. Use the MCP URL for the account's region, `https://mcp.eu.phrase.com` or `https://mcp.us.phrase.com`, and ask the user for the view consent alone unless the task writes\n\n## Questions\n\n### Which is better for AI agents, DeepL API or Phrase?\n\nDeepL API scores 72 (BB) on agent readiness against Phrase's 64.2 (B), and leads in 5 of 7 scored categories.\n\n### Do DeepL API and Phrase need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call DeepL API and Phrase without installing anything?\n\nYes. DeepL API has a hosted endpoint at https://api.deepl.com/v2/translate and Phrase at https://mcp.eu.phrase.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/deepl-api-vs-phrase.json, and with the fewest tokens: https://www.anchorterminal.com/compare/deepl-api-vs-phrase.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"deepl-api\", \"b\": \"phrase\"}`.
