FAQ
Frequently asked questions
Answers for common implementation, authentication, and transcript availability questions.
How do I authenticate requests?
RapidAPI customers authenticate with x-rapidapi-key and x-rapidapi-host headers. Direct backend access requires a private x-api-key.
What are the rate limits?
Rate limits depend on the selected RapidAPI plan. The backend also includes rate limiting to protect service stability.
Which languages are supported?
Language availability depends on captions exposed by YouTube for each video. Use /api/languages to check common transcript languages.
How quickly are responses returned?
Cached responses are typically very fast. First-time transcript lookups depend on YouTube availability and network latency.
