Resize, crop-fit and convert images (PNG, JPEG, WebP, AVIF, GIF, TIFF, SVG input) to webp, png, jpeg or avif. Auto-rotates by EXIF. Use to shrink screenshots before sending them to a vision model, create thumbnails, or convert formats. Params: image_base64 or image_url (one required), width, height (max 4096), fit (inside default | cover | contain | fill), format (webp default), quality (1-100, default 80).

Image Styled API
Generates an illustration from a text prompt with DreamShaper 8 LCM in about 2 seconds: painterly and character art rather than photoreal. Takes a seed for a repeatable result, a negative prompt, and your own width and height. Returns a hosted image URL valid for 24 hours; add inline=true to also get the base64. You are only charged if the image is delivered. No API key, no account.
workers.dev-$0.01listed
Image crop
Crop an image to a pixel box, and/or rotate (90/180/270) and flip it - applied in that order. Send a public image URL or a base64 image. Returns the result as binary, or as a JSON data URI with dataUri:true. Deterministic.
agent402.tools-$0.002listed
Image dominant color
Extract the dominant colors of an image as a palette of hex values with pixel ratios. Send a public image URL or a base64 image, and optionally how many colors (1-10, default 5). Deterministic bucketed quantization; transparent pixels are ignored.

Google Images search for AI agents at $0.004 per call, from the same Serper.dev source as /web/search. Send a query, get back compact JSON: top image results with position, title, image URL, source page link and dimensions. Tune with num (1-10 results), country and language (2-letter codes). Zero results is a valid, honest answer. Pay per call in USDC on Base, no account, no API key.

Implied Volatility API
What the options market expects price to do, not what leverage is doing: the 30-day implied volatility index for BTC and ETH, with its percentile over the last month and the expected move in percent over 1, 7 and 30 days. Funding tells you who is crowded; this tells you how much movement is already priced in — and whether hedging is cheap or expensive relative to where it has been.

Read the messages received by a phone number rented through /v1/sms/number: sender, body, and reception time, returned as structured data so an agent can extract a verification code without human help. The number is a physical SIM in a handset we operate, so it receives from senders that refuse virtual lines.
