No status page, SLA or terms of service for the hosted API.\n\n**Lingo.dev.** Lingo.dev suits teams that want glossary and tone control on every translation call, with a published fee of $2 per million output tokens and model costs passed through. 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## 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### 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## Questions\n\n### Which is better for AI agents, LibreTranslate or Lingo.dev?\n\nLingo.dev scores 62.3 (B) on agent readiness against LibreTranslate's 49.8 (D), and leads in 5 of 7 scored categories.
