How this service works

Analyze any image URL using GPT-4o-mini vision. Returns structured analysis based on the mode: describe (full description), ocr (text extraction), chart (data/trend extraction), ui (interface analysis), identify (object/subject ID), or qa (answer a specific question about the image). Input must be a publicly accessible image URL (JPEG, PNG, GIF, WebP). $0.050/call.

Output

Returns an AI-generated analysis of the image in the requested mode: a full scene description, extracted text (OCR), structured chart data, UI element breakdown, object/subject identification, or a direct answer to a specific question about the image.

When to prefer

Use this endpoint when you need to understand, extract, or answer questions about the content of a publicly accessible image — especially when you want zero-setup API-key-free access paid per-call in USDC. Choose mode=ocr for text extraction, mode=chart for data/graph images, mode=ui for interface screenshots, mode=qa for targeted factual questions, and mode=describe for general scene understanding.

Side effects

Image URL is not publicly accessible or returns a non-image content-type — returns an error indicating invalid or inaccessible image
Image exceeds 20MB file size limit — returns file-too-large error
mode=qa used without a 'question' parameter — returns parameter validation error
Image content violates content policy — returns moderation refusal
Network timeout fetching the remote image URL — returns fetch error
