No status page, SLA or terms of service for the hosted API.\n\n**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.\n\n## Before you call either\n\n### LibreTranslate\n\n1. Split text into calls of 2,000 characters or fewer on the hosted service\n2. Pace to about 20 calls a minute on Pro, since repeated 429s turn into a 403 ban\n3. Pass `source=auto` to detect and translate in one call\n4. Set `format=html` for markup\n5. Read /spec on the server you call, since self-hosted limits and options differ from the hosted ones\n\n### Phrase\n\n1. 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\n2. Send a `User-Agent` header naming your application on every Strings and TMS call. The Strings API answers 400 without one\n3. 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\n4. 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\n5. 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\n\n## Questions\n\n### Which is better for AI agents, LibreTranslate or Phrase?\n\nPhrase scores 64.2 (B) on agent readiness against LibreTranslate's 49.8 (D), and leads in 6 of 7 scored categories. LibreTranslate leads on payments \u0026 pricing.\n\n### Do LibreTranslate and Phrase need an API key?\n\nLibreTranslate needs an API key.
