## Verdicts

**Google Cloud Translation.** 500,000 free characters a month from a $10 credit, and only successful translations bill. Basic (v2) documents the API key as a URL query parameter.

**Lingvanex Translation API.** $5 per million characters list price. Product pages disagree on bulk and on-premise prices.

## Before you call either

### Google Cloud Translation

1. Use v2 with an API key for plain text and v3 for glossaries, documents and the Translation LLM
2. Set `mimeType` to text/plain on v3 when the input isn't HTML
3. Back off on 403 User Rate Limit Exceeded as you would on a 429
4. Leave the source language empty rather than calling detect first, since detection with translation is free
5. Keep requests near 5,000 characters. v3 rejects more than 30,000 code points

### Lingvanex Translation API

1. Call the https:// server, not the http:// one the spec also lists
2. Send `platform` as api on every call, since the spec marks it required
3. Use locale codes such as en_GB and de_DE, not two-letter codes
4. Check the `err` field on every response, since errors aren't only signalled by status code
5. Send an array in `data` to translate several strings in one call
