It has no public OpenAPI file, its `llms.txt` is one line, and scoped keys, roles and audit logs are limited to the Enterprise plan.\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### Lingo.dev\n\n1. Send `X-API-Key` to https://api.lingo.dev and keep the key server-side. On non-Enterprise plans a personal key reaches every engine its creator can\n2. Use `POST /process/localize` for one language pair and `POST /jobs/localization` with an `idempotencyKey` for several. Pipeline stages run on async jobs only\n3. Treat 402 (credit limit) and 429 (daily token quota) as limits to report, not to retry. Retry 500 with backoff\n4. Read `usage.cost` on each sync response to track spend. Sandbox stops at 100,000 tokens a day\n5. Connect MCP clients to https://mcp.lingo.dev/account. Its tools can create and revoke API keys and invite members, so ask before those calls\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, Lingo.dev or SYSTRAN Translate API?\n\nLingo.dev scores 62.3 (B) on agent readiness against SYSTRAN Translate API's 40 (E), and leads in 6 of 7 scored categories. SYSTRAN Translate API leads on payments \u0026 pricing.\n\n### Do Lingo.dev and SYSTRAN Translate API need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Lingo.dev and SYSTRAN Translate API without installing anything?\n\nYes. Lingo.dev has a hosted endpoint at https://mcp.lingo.dev/account and SYSTRAN Translate API at https://api-translate.systran.net.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/lingo-dev-vs-systran.json, and with the fewest tokens: https://www.anchorterminal.com/compare/lingo-dev-vs-systran.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"lingo-dev\", \"b\": \"systran\"}`.
