Verdicts

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.

Lara Translate API

Glossaries, translation memories, styles and instructions on every translate call. Texts may be used for model improvement unless a request sets noTrace.

Before you call either

DeepL API

  1. Match the host to the key. Keys ending :fx go to api-free.deepl.com, others to api.deepl.com
  2. Send the key in the Authorization: DeepL-Auth-Key header, since query and body keys now get 403
  3. Retry 429 and 529 with exponential backoff but stop on 456, which means the quota is spent
  4. Set tag_handling to html for markup so the tags survive and aren't billed
  5. Put a key-level usage limit on any key an agent holds, and scope it to the endpoints it needs

Lara Translate API

  1. Set noTrace on every request that carries private text, since storage for model improvement is the default
  2. Leave reasoning off unless the text needs it. It moves the call to Lara Think at $2,499 per million characters
  3. Resolve glossary and memory names to gls_* and mem_* IDs with the list tools before translating
  4. Send one target language per translate call
  5. Merge short documents, since each file bills at least 20,000 characters
