Check your Litra.ai credit balance and subscription plan. No parameters required.
API access requires a paid Litra.ai subscription (Mini or above). Each search consumes credits from your existing subscription pool.

|---|---|
| Mini | 10 requests/min |
| Standard | 30 requests/min |
| Pro | 60 requests/min |
| Max | 120 requests/min |
See litra-ai.com/pricing for plan details and pricing.
All API responses — including paper titles, summaries, and research overviews — are returned in English only.
This is an intentional design choice for the MCP server and public API:
If your AI workflow requires output in a specific language, the AI client can translate the English response as a post-processing step — this is more reliable than asking the API to translate, since the LLM can adapt the translation to your specific context.
Set the LITRA_API_KEY environment variable in your MCP client configuration. See the Setup section for examples.
Your API key may be incorrect or revoked. Generate a new key at litra-ai.com/account.
Your credit balance is too low. Top up at litra-ai.com/account.
API access requires a paid plan (Mini or above). Subscribe at litra-ai.com/pricing.
You've exceeded your plan's rate limit. Wait a moment and try again, or upgrade your plan for a higher limit.
