Codepen Rate Limits

CodePen does not publicly document rate limits for its oEmbed or Embed APIs; no authentication is required for the oEmbed and POST to Prefill endpoints, and no explicit throttling thresholds have been published.

Codepen Rate Limits is the machine-readable rate-limit profile for CodePen on the APIs.io network, in the API Commons Rate Limits shape.

It captures 3 rate-limit definitions, measuring requests_per_minute.

Limit state is signalled in the retryAfter response header, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes response codes documented for throttled.

Tagged areas include Rate Limiting.
