Scority vs Supadata: YouTube Transcript API Comparison

Compare transcript API options by scope, response shape, authentication, limits, and fit for AI workflows. Verify live pricing and coverage before choosing.

Direct answer

Choose based on the transcript workflow you need

Scority focuses on YouTube transcript extraction for server-side AI, search, RAG, and automation workflows. Supadata may be a better fit if your project needs broader social platform data coverage. This page avoids exact competitor pricing or feature claims that can change without notice.

  • Use Scority when the core job is fetching YouTube transcript text and timestamped segments through a simple HTTP API.
  • Consider broader data providers when you need multiple platforms, non-transcript datasets, or a larger scraping/data product surface.
  • Check each provider's current documentation, coverage, and pricing before making a production decision.
Scority

What Scority provides today

The current public API is intentionally narrow: GET /v1/youtube/transcript on https://api.scority.ai with x-api-key authentication.

Transcript response

Responses include text, segments, source, and language. Segments include text, start, and duration fields.

Open →

Operational errors

The API uses explicit error codes such as unauthorized, rate_limited, quota_exceeded, transcript_not_available, and upstream_transcript_failed.

Open →

Rate limits and quota

Short-window rate limits are separate from monthly quota. Clients should respect Retry-After and X-RateLimit headers.

Comparison criteria

What to compare before switching

Transcript APIs are easy to compare badly. Start with the exact job your product needs, then test the same public videos, languages, errors, and retry behavior against each option.

  • Does the provider return transcript text plus timestamped segments?
  • Can requests be made by video_id and video_url?
  • How are language requests, missing captions, and upstream failures represented?
  • Are authentication, rate limits, quota, and OpenAPI documentation clear?
  • Does the provider cover only transcripts, or a broader data platform that may add cost or complexity?
Use cases

Where each direction can make sense

No comparison page should pretend one vendor is always the right choice. The useful question is whether you want a focused transcript API or a broader data platform.

Scority may fit

You need YouTube transcript text and segments for server-side AI agents, RAG, summarization, search, internal tools, or automation.

Supadata may fit

You need broader social or web data coverage beyond YouTube transcripts and are comfortable validating that broader product surface.

Official APIs may fit

You need Google-managed YouTube metadata, channel, playlist, upload, or platform operations rather than transcript-specific extraction.

Next steps

Test with your real videos

Before choosing, test a representative set of videos, including videos with captions, language-specific requests, and videos where transcripts may be unavailable.
