delete_image Delete image ~64
Permanently delete one PixelVault image by id. Maps to DELETE /v1/images/:id. Requires a PixelVault API key sent as a Bearer token in the Authorization header.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Image id to delete, e.g. img_abc123 |
No output schema declared.
No examples provided.
get_image Get image ~185
Get metadata (CDN URL, size, MIME type, dimensions) for one PixelVault image by id. Maps to GET /v1/images/:id. Requires a PixelVault API key sent as a Bearer token in the Authorization header. The returned CDN URL supports on-the-fly transforms via query params — e.g. ?w=400&fit=cover (resize/crop), ?fmt=webp (format), ?segment=foreground (AI background removal → transparent PNG), effects like ?blur=30&saturation=0&rotate=90, and ?tile=<image_id.ext> (tile another of your images as a watermark). Or call the transform_image tool to build a valid transform URL for you. See https://pixelvault.dev/docs#transforms.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Image id to fetch, e.g. img_abc123 |
No output schema declared.
No examples provided.
list_images List images ~188
List images in your PixelVault project, most recent first. Maps to GET /v1/images with pagination. Requires a PixelVault API key sent as a Bearer token in the Authorization header. The returned CDN URL supports on-the-fly transforms via query params — e.g. ?w=400&fit=cover (resize/crop), ?fmt=webp (format), ?segment=foreground (AI background removal → transparent PNG), effects like ?blur=30&saturation=0&rotate=90, and ?tile=<image_id.ext> (tile another of your images as a watermark). Or call the transform_image tool to build a valid transform URL for you. See https://pixelvault.dev/docs#transforms.
| Name | Type | Req | Description |
|---|---|---|---|
| page | integer | — | Page number (default 1) |
| per_page | integer | — | Items per page (default 20, max 100) |
No output schema declared.
No examples provided.
rescue_imgur Rescue Imgur images ~151
Scan a web page for hotlinked Imgur images and return a PixelVault rescue URL for each — a proxy that lazily rehosts the image on first request, keeping it working through the UK Imgur block. The anonymous rescue tier is a durable ~30-day edge cache (see `cache_ttl_days` in the result), not permanent storage. Maps to POST /v1/imgur-scan (server-side page fetch; no API key required). Provide `page_url` (a public https:// page). Drop each returned rescue_url into your HTML to rehost on first request.
| Name | Type | Req | Description |
|---|---|---|---|
| page_url | string | yes | Public https:// URL of a page to scan for hotlinked Imgur images. |
No output schema declared.
No examples provided.
sign_url Sign private image URL ~153
Mint a time-limited signed URL for a private image. Maps to POST /v1/images/:id/sign-url. Provide `id` and optional `expires_in` (seconds, default 3600). The signature binds the image, so the URL can't be replayed against another image; strip it and the CDN returns 403. Deleting the image revokes its URLs. Requires a PixelVault API key sent as a Bearer token in the Authorization header.
| Name | Type | Req | Description |
|---|---|---|---|
| expires_in | integer | — | Signature lifetime in seconds (60–2,592,000). Default 3600 (1 hour). |
| id | string | yes | Image id to mint a signed URL for, e.g. img_abc123. |
No output schema declared.
No examples provided.
transform_image Build transform URL ~791
Build an on-the-fly transform URL for a PixelVault image (resize, crop, format/quality, AI background removal, blur/sharpen/rotate/flip, brightness/contrast/saturation, and same-project watermark tiling). Provide exactly one of `url` (a PixelVault CDN URL) or `id` (an image id, resolved via the API — requires an API key), plus one or more transform params. Returns the ready-to-use CDN URL; the transform is produced and cached on first request. See https://pixelvault.dev/docs#transforms.
| Name | Type | Req | Description |
|---|---|---|---|
| background | string | — | Fill color behind a removed (segment) or padded (fit=pad) background: hex (#ffaa00), rgb()/rgba(), or a common CSS color name. No effect otherwise. |
| blur | number | — | Gaussian blur (0-250); snapped to the nearest of 10/30/60/120. <=0 is ignored. |
| brightness | number | — | Brightness multiplier 0-2 (1=no change); snapped to 0.5/0.75/1.25/1.5/2. |
| contrast | number | — | Contrast multiplier 0-2 (1=no change); snapped to 0.5/0.75/1.25/1.5/2. |
| fit | string | — | Resize mode. scale-down (default) never enlarges; contain/cover/crop/pad resize to the exact box and may upscale. Only meaningful alongside width/height. |
| flip | string | — | Mirror horizontally (h), vertically (v), or both (hv). |
| format | string | — | Output format. auto negotiates WebP/AVIF from the client's Accept header. |
| gravity | string | — | Crop anchor, only with fit=cover|crop: face, left, right, top, bottom, auto, or 'XxY' coords 0.0-1.0. face enables zoom. |
| height | integer | — | Target height in px (1..4000). Snapped UP to the nearest allowed step. |
| id | string | — | PixelVault image id (e.g. img_abc123); its CDN URL is resolved via the API. Provide this OR url. Requires an API key when used. |
| quality | string | — | Output quality. auto lets Cloudflare choose. |
| rotate | number | — | Rotate clockwise; rounded to the nearest right angle (90/180/270). |
| saturation | number | — | Saturation multiplier 0-2 (1=no change, 0=grayscale); snapped to 0/0.5/1.5/2. |
| segment | string | — | AI background removal (BiRefNet): foreground keeps the subject and makes the background transparent. Output is forced to PNG unless an opaque background is set. Not available on anonymous/playground… |
| sharpen | number | — | Sharpen strength (0-10); snapped to the nearest of 1/3/5. |
| size | string | — | Named size preset: s=256px, m=640px, l=1280px, social=1200x630 OG card. Wins over width/height. |
| tile | string | — | Filename (optionally folder-prefixed, with extension) of another image in the SAME project to tile edge-to-edge as a watermark, e.g. watermark.png. |
| url | string | — | Absolute CDN URL of a PixelVault image, as returned by upload_image / get_image / list_images. Provide this OR id. |
| width | integer | — | Target width in px (1..4000). Snapped UP to the nearest allowed step. scale-down never upscales. |
| zoom | number | — | Face-crop tightness 0.0-1.0, only with gravity=face. |
No output schema declared.
No examples provided.
upload_batch Upload image batch ~481
Upload many images (1–50) in one call, grouped into a collection — e.g. a CI run or a set of generated variants. Maps to POST /v1/images/batch. Each item is `data` (base64) or `source_url` (server-fetched, SSRF-guarded), with optional `filename`/`metadata`. Set `visibility: "private"` to get a signed URL per image (free plan: up to 100 private images) instead of a public CDN URL. Optional `type`/`name` (idempotent by (type, name)), `expires_in` (image TTL), `sign_expires_in` (signature lifetime), and collection `metadata`. Partial-failure tolerant: each returned item has its own `ok`. Requires a PixelVault API key sent as a Bearer token in the Authorization header. The returned CDN URL supports on-the-fly transforms via query params — e.g. ?w=400&fit=cover (resize/crop), ?fmt=webp (format), ?segment=foreground (AI background removal → transparent PNG), effects like ?blur=30&saturation=0&rotate=90, and ?tile=<image_id.ext> (tile another of your images as a watermark). Or call the transform_image tool to build a valid transform URL for you. See https://pixelvault.dev/docs#transforms.
| Name | Type | Req | Description |
|---|---|---|---|
| expires_in | integer | — | Image deletion TTL in seconds (60–2,592,000). Omit for permanent. |
| images | array | yes | 1–50 images to upload into the collection. |
| metadata | object | — | Freeform collection metadata, e.g. { commit, pr_number, branch }. |
| name | string | — | Idempotency key — re-running with the same (type, name) upserts the same collection. |
| sign_expires_in | integer | — | Signature lifetime for private URLs in seconds (60–2,592,000, default 7 days). |
| type | string | — | Collection type/discriminator (e.g. ci_build, generation). Default 'batch'. |
| visibility | string | — | 'private' returns a signed URL per image (free plan: up to 100 private images); 'public' returns a plain CDN URL. Default 'public'. |
No output schema declared.
No examples provided.
upload_image Upload image ~358
Upload an image to PixelVault and get an instant CDN URL. Maps to POST /v1/images. Provide exactly one of `source_url` (a public http(s) URL the server fetches) or `data` (base64-encoded bytes); optional `folder`, `filename`, and `expires_in` (seconds, for an auto-expiring image). Max 5 MB; JPG/PNG/GIF/WebP/AVIF/SVG. Requires a PixelVault API key sent as a Bearer token in the Authorization header. The returned CDN URL supports on-the-fly transforms via query params — e.g. ?w=400&fit=cover (resize/crop), ?fmt=webp (format), ?segment=foreground (AI background removal → transparent PNG), effects like ?blur=30&saturation=0&rotate=90, and ?tile=<image_id.ext> (tile another of your images as a watermark).
