estimate_cost

Estimate the price of an operation Returns the exact USD price this API would charge for an operation on an input of the given size, without fetching or processing anything. Free. Use it before paying: send X-Max-Cost-USD on the real request to have the API refuse (412) instead of charging more than you allowed. The list price is returned even when the request could end up free (free tier, or a compress that does not shrink the file). ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "operation": "Operation", "price_usd": 1.0, "base_usd": 1.0, "surcharges_usd": {}, "size_multiplier": 1.0, "within_free_tier": true, "free_tier_remaining": 1, "currency": "Currency", "network": "Network" } ```

Parameters5

operation	string	required	Operation to price. One of resize, compress, convert, crop, optimize_for_vision, optimize_generated, pipeline. analyze is always free.
input_bytes	integer	required	Size of the input image in bytes. Get it from analyze_image (free) if you do not know it.
format	string	optional	Requested output format; only avif changes the price.

analyze_image

Analyze an image Fetch an image from a URL or base64 and return its metadata: size in bytes, pixel dimensions, source format, and what it costs every supported vision model in tokens. Always free. Dimensions are omitted if the image header cannot be read. Also reports whether the input carries a C2PA (Content Credentials) manifest and in which container; the manifest is not validated. ### Responses: **200**: Successful Response (Success Response) Content-Type: application/json **Example Response:** ```json { "size_bytes": 1, "c2pa_manifest": true } ```

Parameters1

source

string

required

Image source: a public URL (https://...) or a base64-encoded string (optionally as a data URI like data:image/png;base64,...).

resize_image

Resize an image Scale an image by a factor, or fill an exact box. Use 'scale' for uniform scaling, or 'scale_x'/'scale_y' for independent axes (float factors, e.g. 0.5 = half size). Alternatively set 'width'+'height' for fill mode: resize and smart-crop to those exact dimensions in one call (optional 'gravity', default attention). The two modes are mutually exclusive. Optional enhancement modifiers: denoise (1-3), equalize, sharpen (applied denoise -> equalize -> op -> sharpen). ### Responses: **200**: Processed image binary (Success Response) Content-Type: application/json Content-Type: image/jpeg **Example Response:** ```json "string" ``` Content-Type: image/png **Example Response:** ```json "string" ``` Content-Type: image/webp **Example Response:** ```json "string" ```

Parameters13

delivery	string	optional
source	string	required	Image source: a public URL (https://...) or a base64-encoded string (optionally as a data URI like data:image/png;base64,...).
scale_x	number	optional	Horizontal scale factor (e.g. 0.5 = half width). If only scale_x is given, scale_y defaults to the same value.
scale_y	number	optional	Vertical scale factor (e.g. 0.75 = 75% height). Optional; defaults to scale_x if omitted.
scale	number	optional	Uniform scale factor applied to both axes (e.g. 0.5 = half size). Use this for simple scaling; use scale_x/scale_y for independent axes.
format	string	optional	Output format: jpeg, png, webp, tiff, gif, or avif. If omitted, the original format is preserved.
width	integer	optional	Target width in pixels for fill mode: resize and smart-crop to these exact dimensions in one call. Requires height. Mutually exclusive with scale/scale_x/scale_y. Upscaling is allowed.
height	integer	optional	Target height in pixels for fill mode. Requires width.
gravity	string	optional	Fill-mode smart-crop strategy: one of ('attention', 'entropy', 'centre'). Only valid together with width and height; defaults to attention.
autorot	boolean	optional	Apply EXIF orientation before resizing. Opt-in; default false, which preserves current byte-for-byte behavior.
denoise	integer	optional	Median denoise before resizing: radius 1-3 (window 3x3 to 7x7). Opt-in; no surcharge.
equalize	boolean	optional	Auto-contrast (histogram equalisation of the value channel; hue and saturation preserved) before resizing. Opt-in.
sharpen	boolean	optional	Unsharp-mask sharpen after resizing (libvips defaults). Opt-in.

compress_image

Compress an image Re-encode an image with quality/format options to reduce file size. Supports jpeg, png, webp, tiff, gif. Instead of a q number you can set quality_target (0-1]: the smallest file with SSIM at or above the target, searched on the worker (jpeg, webp, avif; flat surcharge; outcome reported in X-Pictomancer-Quality-* headers). If the output is not smaller than the input, the request is free (X-Pig-Billed: 0) and does not consume free-tier quota. Optional enhancement modifiers: denoise (1-3), equalize, sharpen (applied denoise -> equalize -> op -> sharpen). ### Responses: **200**: Processed image binary (Success Response) Content-Type: application/json Content-Type: image/jpeg **Example Response:** ```json "string" ``` Content-Type: image/png **Example Response:** ```json "string" ``` Content-Type: image/webp **Example Response:** ```json "string" ```

Parameters10

delivery	string	optional
source	string	required	Image source: a public URL (https://...) or a base64-encoded string (optionally as a data URI like data:image/png;base64,...).
q	integer	optional	Quality (1-100). Lower = smaller file. Typical values: 60-80 for web, 85-95 for print. Maps to libvips Q parameter.
format	string	optional	Output format: jpeg, png, webp, tiff, gif, or avif. If omitted, the original format is preserved.
strip	boolean	optional	Strip metadata (EXIF, ICC profile, etc.) from the output. Reduces file size slightly.
quality_target	number	optional	Target SSIM (0-1]: the worker searches for the smallest file that still scores at least this. Alternative to q; mutually exclusive with it. Requires an explicit format among jpeg, webp, avif. Carries a flat surcharge for the extra encodes.
autorot	boolean	optional	Apply EXIF orientation before compressing. Opt-in; default false, which preserves current byte-for-byte behavior.
denoise	integer	optional	Median denoise before compressing: radius 1-3 (window 3x3 to 7x7). Opt-in; no surcharge.
equalize	boolean	optional	Auto-contrast (histogram equalisation of the value channel; hue and saturation preserved) before compressing. Opt-in.
sharpen	boolean	optional	Unsharp-mask sharpen after compressing (libvips defaults). Opt-in.

convert_image

Convert image format Convert an image to a different format (jpeg, png, webp, tiff, gif, avif). Optionally set quality, strip metadata, enable lossless mode (webp, avif), or tune encoder effort (avif). Instead of a q number you can set quality_target (0-1]: the smallest file with SSIM at or above the target, searched on the worker (jpeg, webp, avif; flat surcharge; outcome reported in X-Pictomancer-Quality-* headers). Optional enhancement modifiers: denoise (1-3), equalize, sharpen (applied denoise -> equalize -> op -> sharpen). ### Responses: **200**: Processed image binary (Success Response) Content-Type: application/json Content-Type: image/jpeg **Example Response:** ```json "string" ``` Content-Type: image/png **Example Response:** ```json "string" ``` Content-Type: image/webp **Example Response:** ```json "string" ```

Parameters12

delivery	string	optional
source	string	required	Image source: a public URL (https://...) or a base64-encoded string (optionally as a data URI like data:image/png;base64,...).
format	string	required	Target format: jpeg, png, webp, tiff, gif, or avif.
q	integer	optional	Quality (1-100). Maps to libvips Q parameter.
strip	boolean	optional	Strip metadata (EXIF, ICC profile, etc.) from the output.
lossless	boolean	optional	Enable lossless encoding. Only applies to webp and avif.
effort	integer	optional	AV1 encoder CPU effort (0-9). Higher = smaller file, slower. Only applies to avif.
quality_target	number	optional	Target SSIM (0-1]: the worker searches for the smallest file that still scores at least this. Alternative to q; mutually exclusive with it and with lossless. Only for jpeg, webp, avif. Carries a flat surcharge for the extra encodes.
autorot	boolean	optional	Apply EXIF orientation before converting. Opt-in; default false, which preserves current byte-for-byte behavior.
denoise	integer	optional	Median denoise before converting: radius 1-3 (window 3x3 to 7x7). Opt-in; no surcharge.
equalize	boolean	optional	Auto-contrast (histogram equalisation of the value channel; hue and saturation preserved) before converting. Opt-in.
sharpen	boolean	optional	Unsharp-mask sharpen after converting (libvips defaults). Opt-in.

crop_image

Crop an image Extract a rectangular region from an image, in one of three mutually exclusive modes. Manual: give the top-left corner (x, y) and dimensions (width, height) in pixels. Smart crop: give 'gravity' (attention, entropy, centre) plus width and height; the window is picked automatically, clamped to the source if the target is larger. Trim: set 'trim: true' (optional 'threshold') to remove a uniform background border via content detection; the applied rect is reported in X-Pictomancer-Trim-* headers. Optional enhancement modifiers: denoise (1-3), equalize, sharpen (applied denoise -> equalize -> op -> sharpen). ### Responses: **200**: Processed image binary (Success Response) Content-Type: application/json Content-Type: image/jpeg **Example Response:** ```json "string" ``` Content-Type: image/png **Example Response:** ```json "string" ``` Content-Type: image/webp **Example Response:** ```json "string" ```

Parameters14

delivery	string	optional
source	string	required	Image source: a public URL (https://...) or a base64-encoded string (optionally as a data URI like data:image/png;base64,...).
x	integer	optional	Left edge of the crop rectangle in pixels. Manual mode only.
y	integer	optional	Top edge of the crop rectangle in pixels. Manual mode only.
width	integer	optional	Width of the crop rectangle in pixels. Required in manual and gravity modes.
height	integer	optional	Height of the crop rectangle in pixels. Required in manual and gravity modes.
gravity	string	optional	Smart-crop mode: picks the window automatically. One of ('attention', 'entropy', 'centre'). Requires width and height; mutually exclusive with x/y and trim. A target larger than the source clamps to the source size.
trim	boolean	optional	Trim mode: removes a uniform background border via content detection. Mutually exclusive with x/y/width/height/gravity.
threshold	number	optional	Trim sensitivity (must be positive; default 10.0). Only valid together with trim: true.
autorot	boolean	optional	Apply EXIF orientation before cropping. Opt-in; default false, which preserves current byte-for-byte behavior.
denoise	integer	optional	Median denoise before cropping: radius 1-3 (window 3x3 to 7x7). Opt-in; no surcharge.
equalize	boolean	optional	Auto-contrast (histogram equalisation of the value channel; hue and saturation preserved) before cropping. Opt-in.
sharpen	boolean	optional	Unsharp-mask sharpen after cropping (libvips defaults). Opt-in.
format	string	optional	Output format: jpeg, png, webp, tiff, gif, or avif. If omitted, the original format is preserved.

optimize_for_vision

Resize an image for a vision model Resize an image to the largest size a given vision model still benefits from, and report what it costs that model in tokens before and after. Every provider downscales oversized input before counting tokens, so this alone saves bytes and upload latency rather than tokens. Pass max_tokens to trade resolution for tokens: that lever is continuous on Claude, unavailable on OpenAI (cost follows the aspect ratio alone), and on Gemini reaches only a flat 258. An image already within budget is returned untouched and free (X-Pig-Billed: 0). ### Responses: **200**: Processed image binary (Success Response) Content-Type: application/json Content-Type: image/jpeg **Example Response:** ```json "string" ``` Content-Type: image/png **Example Response:** ```json "string" ``` Content-Type: image/webp **Example Response:** ```json "string" ```

Parameters6

delivery	string	optional
source	string	required	Image source: a public URL (https://...) or a base64-encoded string (optionally as a data URI like data:image/png;base64,...).
target_model	string	required	Vision model the image is being prepared for, e.g. claude-opus-5, gpt-4o, gemini-2.5-pro. Unknown ids are rejected rather than guessed: the wrong limits would silently resize to the wrong size.
max_tokens	integer	optional	Optional cap on what the image may cost the target model. Without it the image is resized to the model's own ceiling, which saves bytes and upload latency but no tokens, because every provider already downscales oversized input before counting. Set a budget to trade resolution for tokens. The response reports the cost actually achieved: on OpenAI it cannot be lowered by resizing at all, and on Gemini only down to a flat 258.
format	string	optional	Output format: jpeg, png, webp, tiff, gif, or avif. If omitted, the original format is preserved.
q	integer	optional	Quality (1-100). Maps to libvips Q parameter.

optimize_generated_image

Optimize an AI-generated image for the web The step after image generation. gpt-image, DALL-E, Flux, Midjourney and Stable Diffusion hand back 2-8 MB PNGs; this returns the same picture as a web-ready webp (default), avif, jpeg or png, metadata stripped, transparency kept on webp/avif/png. Optional max_dimension caps the longest side (never upscales); optional q or quality_target (smallest file with SSIM >= target, flat surcharge) control quality. Same price as convert. If the result is not smaller than the input it is still returned but free (X-Pig-Billed: 0). X-Pictomancer-Bytes-Before/-After/-Saved-Percent report the saving. The input's C2PA manifest, if any, is reported in X-Pictomancer-C2PA-Input but is not carried over: re-encoding invalidates it. ### Responses: **200**: Processed image binary (Success Response) Content-Type: application/json Content-Type: image/jpeg **Example Response:** ```json "string" ``` Content-Type: image/png **Example Response:** ```json "string" ``` Content-Type: image/webp **Example Response:** ```json "string" ```

Parameters7

delivery	string	optional
source	string	required	Image source: a public URL (https://...) or a base64-encoded string (optionally as a data URI like data:image/png;base64,...).
format	string	optional	Output format: webp (default), avif, jpeg or png. webp, avif and png keep transparency; jpeg flattens it.
q	integer	optional	Quality (1-100). Maps to libvips Q parameter. Omit to use the encoder default; or set quality_target instead.
quality_target	number	optional	Target SSIM (0-1]: the worker searches for the smallest file that still scores at least this. Alternative to q; mutually exclusive with it. Carries a flat surcharge for the extra encodes.
max_dimension	integer	optional	Cap on the longest side in pixels. Larger images are scaled down to fit, aspect ratio preserved; smaller images are never upscaled.
strip	boolean	optional	Strip metadata. Defaults to true: generated images carry no EXIF worth keeping. Metadata includes any C2PA manifest, which would be invalid after re-encoding anyway.
