## Which one, for what

### Lara Translate API (C)

Good for: Agents that localise for one brand and need glossaries, translation memories and style instructions on every call, especially from an MCP client.

Ahead on:
- Reliability, 70 against 25
- Schema & documentation, 74 against 42
- Agent ergonomics, 77 against 54
- Maintenance & community, 83 against 4
- Transparency & trust, 60 against 51

Also in its favour:
- Runs on your own machine

Watch for: Texts may be used for model improvement unless a request sets `noTrace`

### SYSTRAN Translate API (E)

Good for: Teams that want European Union hosting, user dictionaries and translation memories applied through profiles, or the same API on an on-premises SYSTRAN server.

Ahead on:
- Security & auth, 55 against 30

Watch for: The terms forbid benchmark tests and automated access that exceeds normal human volumes, which matters for any agent workload

## 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
