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**Smartcat.** Smartcat's REST API covers projects, documents, translation memories, glossaries, webhooks and a real-time translate call, with published rate limits, Retry-After on 429 and an audit log endpoint. Keys are account-wide with no documented scopes, the status page lists two incidents of an hour or more in 90 days, and API access is listed only from the $60,000-a-year Anticipate plan.\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### Smartcat\n\n1. Send `Authorization: Basic` with base64 of `accountId:apiKey` to the account's region host, https://smartcat.ai, https://us.smartcat.ai or https://ea.smartcat.ai.\n2. On 429, wait the seconds in Retry-After before retrying. The 429 itself carries no `x-rate-limit-*` headers.\n3. Create a smart translation profile in the web app first and pass its ID as `profile` to `smartTranslation/translate`.\n4. Store each `requestUid` and look charges up later with `smartTranslation/charges`, since the translate response doesn't include the cost.\n5. Treat callbacks as hints and poll project, document or export status as a fallback, because failed deliveries are dropped after the last retry.\n\n## Questions\n\n### Which is better for AI agents, Lingo.dev or Smartcat?\n\nLingo.dev scores 62.4 (B) on agent readiness against Smartcat's 54.3 (C), and leads in 4 of 7 scored categories. Smartcat leads on schema \u0026 documentation and payments \u0026 pricing.\n\n### Do Lingo.dev and Smartcat need an API key?\n\nLingo.dev takes an API key or an OAuth sign-in. Smartcat needs an API key.\n\n### Can an agent call Lingo.dev and Smartcat without installing anything?\n\nYes. Lingo.dev has a hosted endpoint at https://mcp.lingo.dev/account and Smartcat at https://smartcat.ai/api/integration.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/lingo-dev-vs-smartcat.json, and with the fewest tokens: https://www.anchorterminal.com/compare/lingo-dev-vs-smartcat.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"lingo-dev\", \"b\": \"smartcat\"}`.
