## Which one, for what

### Google Cloud Translation (B)

Good for: Agents on Google Cloud that want high quotas, clear data terms and a choice of NMT, LLM or adaptive translation with glossaries.

Ahead on:
- Reliability, 90 against 55
- Security & auth, 80 against 58
- Transparency & trust, 79 against 74

Watch for: Basic (v2) documents the API key as a URL query parameter

### Phrase (B)

Ahead on:
- Schema & documentation, 87 against 70
- Payments & pricing, 30 against 20
- Maintenance & community, 83 against 38

Also in its favour:
- Free to start without a card

## 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.

**Phrase.** Nine APIs with public OpenAPI specs, Markdown docs and a hosted MCP server that signs in with OAuth and separates view, create and delete consents. The status page lists 14 incidents in 90 days, 12 marked major or critical. Capacity top-up prices aren't public, and the terms permit training some models on customer content and prohibit benchmarking.

## 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

### Phrase

1. Exchange a Phrase Platform API token at `https://eu.phrase.com/idm/oauth/token` (or `us.phrase.com`) for a Bearer JWT, which lasts about four hours, and refresh it before it expires
2. Send a `User-Agent` header naming your application on every Strings and TMS call. The Strings API answers 400 without one
3. Keep Strings calls under 1,000 in five minutes and four in parallel, and read `X-Rate-Limit-Reset` and `X-Rate-Limit-Reason` on a 429
4. Send at most six texts of 2,000 characters to `/v2/textTranslations`, with `consumerId` and `targetLang`. Term bases and translation memories work only with an AI translation agent profile
5. Use the MCP URL for the account's region, `https://mcp.eu.phrase.com` or `https://mcp.us.phrase.com`, and ask the user for the view consent alone unless the task writes
