# pinterest.image_url.reachable

> Pinterest fetches the pin image from the URL you provide. It must respond 200 anonymously.

## What it checks

Active probe — we HEAD the image URL during preflight. If the response isn't a 2xx that resolves to image bytes, the rule fires.

Same failure modes as [`instagram.media.reachable`](/preflight/instagram-media-reachable): Drive share links, Dropbox previews, S3 with restricted ACLs.

## Remediation

Use [`POST /v1/media`](/guides/upload-media) and reference the returned `mediaId`. The result URL is on our public CDN and Pinterest fetches it cleanly.
