How this service works
One pay-per-call API for AI agents: optimization, AI, research, on-chain data, and automation — all settled in USDC on Base via x402. Discover via MCP and Bazaar, estimate free, pay per call. No API keys, no signup.
Output
A text response describing the image contents, including a natural-language caption, description of visible objects and scenes, and any text extracted via OCR — generated by Gemini vision through OpenRouter.
Example use cases
Auto-captioning product photos
“I have a product image at https://shop.example.com/item42.jpg — can you describe what it shows so I can generate alt text and a product blurb from it?”
OCR text extraction from receipt
“Please read all the text you can see in this receipt photo: https://myfiles.example.com/receipt_march.jpg — I need the merchant name, date, and total amount.”
Analyzing a screenshot for support
“Here's a screenshot of an error message a user sent us: https://support.example.com/ticket99/screen.png — can you describe what it says and what the UI looks like so I can diagnose the issue?”
