Verdicts

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.

SYSTRAN Translate API

Five documented REST APIs cover text, files, dictionaries, translation memories and profiles, with a Google-compatible mode and a public price of €14.99 per million characters. The reference pages date from June 2023, and no changelog, status page, rate limit, SDK or downloadable OpenAPI file was found. The terms bar benchmark tests and automated use beyond human volumes.

Before you call either

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

SYSTRAN Translate API

  1. Send the key as Authorization: Key <api_key> and avoid the documented ?key= query option, which puts the secret in URLs and logs
  2. Expect HTTP 400, not 401, when credentials are missing. The body reads No key / credentials provided
  3. Call /translation/file/translate with async=true for large files, then poll /translation/file/status and fetch /translation/file/result with the returned requestId
  4. Apply dictionaries and translation memories through a profile and pass its UUID as profile. withDictionary and withCorpus are deprecated
  5. Read the terms before automating. They bar benchmark tests and request volumes beyond normal human use, and SYSTRAN may throttle or suspend access
