shallowio.agentsvc/services · Verify this server
Alt text for images, for web accessibility (WCAG 1.1.1, BFSG, European Accessibility Act) and SEO: send image_url or image_base64, get alt text under 125 characters that describes purpose and content, a longer description for complex images such as charts, whether the image is decorative (then alt=""), all readable text in the image, and a ready alt="..." attribute. Optional language (e.g. German) and context (where the image is used). The image is scaled to at most 800 x 800 px first, then described by Claude Haiku 5.5. Pairs with accessibility-check, which finds images without alt text. Price: $0.005 USDC per call, paid inside this MCP call via x402 (USDC on Base, Solana, Polygon or Arbitrum). x402 MCP clients such as @x402/mcp pay automatically. Free sample: call with the example input {"image_url":"https://upload.wikimedia.org/wikipedia/commons/thumb/3/3f/Fronalpstock_big.jpg/1280px-Fronalpstock_big.jpg"}.
