# Refine a post

`POST /api/apps/{app_id}/virality/posts/{post_id}/refine`

<Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

Rewrites a single post in the content plan according to your request, and returns the whole updated plan.

Take `post_id` from a post in the plan. Only that post changes. Every other post is returned unchanged. To replace a post's text yourself instead of having it rewritten, use [Update post content](/api-reference/update-post-content).

This request costs 1 credit and fails with a 402 when the workspace is out of quota. It calls a language model, so expect it to take a few seconds.

<Warning>Editing the same post while a refinement is in flight discards the refinement, and the request fails with a **500**, not a 409. Retrying is the right response, but check the post's current `content` first, because your edit is the version that survived. A 409 here means something different. It signals repeated write conflicts on the plan that did not settle.</Warning>

This endpoint shares a limit of 15 requests per minute with the other social content endpoints.

<Note>This endpoint accepts a personal API key. Workspace API keys are not authorized for it and are rejected with a 403.</Note>

<Warning>The response includes fields beyond the ones documented here. Don't rely on undocumented response fields, as they can change at any time. Send only the fields documented here. Other request fields are not supported and their behavior can change.</Warning>
