## 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
