<PlansAvailable plans={["premium"]} maxPackRequired={false} />

Calculate the weighted length, or character count, of a post string for Bluesky, Facebook, Google Business Profile, Instagram, LinkedIn, Pinterest, Reddit, Threads, TikTok, X/Twitter, and YouTube. Checks if the post length is valid and returns the maximum length allowed for each social network.

Special characters, such as ü, ø, or 😊, have a higher character count value (unicode).

This check is automatically done with the /post endpoint.

<Info>The weighted length is an estimate calculated by Ayrshare. Social networks may have slightly different character counts based on their own calculation methods.</Info>

## Header Parameters

<HeaderAPI noProfileKey={true} />

## Body Parameters

<ParamField body="post" type="string" required>
  Post string to calculate the length.
</ParamField>
