Product pages disagree on bulk and on-premise prices.\n\n**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.\n\n## Before you call either\n\n### Lingvanex Translation API\n\n1. Call the https:// server, not the http:// one the spec also lists\n2. Send `platform` as api on every call, since the spec marks it required\n3. Use locale codes such as en_GB and de_DE, not two-letter codes\n4. Check the `err` field on every response, since errors aren't only signalled by status code\n5. Send an array in `data` to translate several strings in one call\n\n### SYSTRAN Translate API\n\n1. Send the key as `Authorization: Key \u003capi_key\u003e` and avoid the documented `?key=` query option, which puts the secret in URLs and logs\n2. Expect HTTP 400, not 401, when credentials are missing. The body reads `No key / credentials provided`\n3. Call `/translation/file/translate` with `async=true` for large files, then poll `/translation/file/status` and fetch `/translation/file/result` with the returned `requestId`\n4. Apply dictionaries and translation memories through a profile and pass its UUID as `profile`. `withDictionary` and `withCorpus` are deprecated\n5. Read the terms before automating. They bar benchmark tests and request volumes beyond normal human use, and SYSTRAN may throttle or suspend access\n\n## Questions\n\n### Which is better for AI agents, Lingvanex Translation API or SYSTRAN Translate API?\n\nSYSTRAN Translate API scores 40 (E) on agent readiness against Lingvanex Translation API's 37 (F), and leads in 4 of 7 scored categories.
