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### DeepL API\n\n1. Match the host to the key. Keys ending `:fx` go to api-free.deepl.com, others to api.deepl.com\n2. Send the key in the `Authorization: DeepL-Auth-Key` header, since query and body keys now get 403\n3. Retry 429 and 529 with exponential backoff but stop on 456, which means the quota is spent\n4. Set `tag_handling` to html for markup so the tags survive and aren't billed\n5. Put a key-level usage limit on any key an agent holds, and scope it to the endpoints it needs\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, DeepL API or Lingo.dev?\n\nDeepL API scores 72 (BB) on agent readiness against Lingo.dev's 62.3 (B), and leads in 5 of 7 scored categories. Lingo.dev leads on reliability.\n\n### Do DeepL API and Lingo.dev need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call DeepL API and Lingo.dev without installing anything?\n\nYes. DeepL API has a hosted endpoint at https://api.deepl.com/v2/translate and Lingo.dev at https://mcp.lingo.dev/account.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/deepl-api-vs-lingo-dev.json, and with the fewest tokens: https://www.anchorterminal.com/compare/deepl-api-vs-lingo-dev.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"deepl-api\", \"b\": \"lingo-dev\"}`.
