APIs used

Only endpoints that exist in the generated endpoint metadata are linked here. Missing optional endpoints are intentionally omitted.

GETYouTubeapiKey3 credits/request

Retrieve transcript for a YouTube video

/youtube/transcript/{id}

Returns transcript segments for a YouTube video using YouTube's native player captions. Set `format=text`, `format=srt`, or `format=vtt` to receive plain-text output instead of the standard response envelope.

Example request

This example uses the real Retrieve transcript for a YouTube video endpoint. Exact request fields come from the endpoint metadata.

Recipe request

Use environment variables for secrets and keep Crawlora API keys server-side.

curl -X GET "https://api.crawlora.net/api/v1/youtube/transcript/dQw4w9WgXcQ?lang=en&format=json&timestamps=true" \
  -H "x-api-key: $CRAWLORA_API_KEY"

Example response

Use endpoint detail pages for exact response schemas. This recipe does not invent response fields.

Generated example response

{
  "code": 200,
  "msg": "OK",
  "data": {
    "video_id": "dQw4w9WgXcQ",
    "language": "English",
    "language_code": "en",
    "segments": [
      {
        "text": "Never gonna give you up",
        "start": 12.34,
        "duration": 2.11
      }
    ],
    "text": "Never gonna give you up"
  }
}

Storage/output suggestion

Keep raw transcript segments and a derived summary table so downstream analysis can be regenerated.

Error handling

Validate required inputs before calling Crawlora
Retry 429 and temporary 5xx responses with capped backoff
Log endpoint, input, timestamp, and request ID when present
Treat empty results as a state your application can handle
Open /docs/errors for production retry guidance

Rate-limit and credit planning

Estimate usage by multiplying requests by endpoint credit cost. The table below only shows real credit costs available from the billing constants.

Endpoint	Credit cost	Docs
Retrieve transcript for a YouTube video	3 credits/request	/docs/YouTube/youtube-transcript
Retrieve video metadata & captions	3 credits/request	/docs/YouTube/youtube-video

Production checklist

Keep API keys server-side
Use request timeouts
Back off on rate limits
Store raw responses or source IDs for auditability
Monitor credits and failures
Avoid unnecessary refreshes
Review responsible-use requirements
