Compare two JSON objects or arrays and get a structured list of differences. Returns RFC 6902-style patch operations (add, remove, replace) with JSON Pointer paths (RFC 6901). Useful for change detection, audit logging, config comparison, and finding what changed between two API responses. Send {"left": <original>, "right": <modified>}. Optional: includeUnchanged (bool) includes unchanged paths; maxDepth (int 1–256, default 64) limits traversal depth.
Remove all embedded metadata (EXIF, XMP, IPTC) from a JPEG or PNG image and return the cleaned image binary. Use this to strip GPS coordinates, camera info, author data, and other privacy-sensitive metadata before sharing or publishing images. Send raw binary body (Content-Type: image/jpeg or image/png) or multipart/form-data with field 'file'. Max 5 MB. Returns cleaned binary image with Content-Type matching the original format.
Fetch a URL and return its text content. Auto-detects the format: HTML is converted to Markdown, JSON is returned as formatted text, and Markdown or plain text is returned as-is. Use when you need to read any URL without knowing its content type in advance. Send {"url": "https://..."}. Remote fetch timeout: 5s, max download size: 2 MB.
Count the number of tokens in a text string using the specified tokenizer encoding. Supports cl100k_base (GPT-4/GPT-3.5, exact BPE), o200k_base (GPT-4o, exact BPE), claude (Claude models, estimated), and gemini (Gemini models, estimated). Use before sending text to an LLM to estimate cost, check context window fit, or enforce token budgets. For base64-encoded images, set content_type='image' for tile-based token estimation. Send {"text": "...", "encoding": "cl100k_base"}. Max 50 MB text.
