Quiver

AI-powered SVG generation and image vectorization service using QuiverAI's Arrow model. Generate scalable vector graphics from text prompts or convert raster images to clean SVG format. Through the Polymer Pay proxy, each request is paid individually — no QuiverAI account or API key required.

Authentication

All requests route through the Polymer Pay proxy. Include your Polymer Pay API key in every request:

{
  "headers": {
    "Content-Type": "application/json",
    "x-polymer-pay-api-key": "{{POLYMER_PAY_API_KEY}}"
  }
}

Base URL: https://pay.polymerlabs.org/proxy/https/quiver.x402endpoints.com

To get an Polymer Pay API key, sign up at https://my.pay.polymerlabs.org/dashboard/api-keys.

Common Operations

Generate SVG from Text

Generate scalable vector graphics from a text description using AI.

Pricing: $0.30

{
  "method": "POST",
  "url": "https://pay.polymerlabs.org/proxy/https/quiver.x402endpoints.com/v1/svgs/generations",
  "headers": {
    "Content-Type": "application/json",
    "x-polymer-pay-api-key": "{{POLYMER_PAY_API_KEY}}"
  },
  "body": {
    "prompt": "a minimalist logo of a mountain with a sun rising behind it"
  }
}

Response: JSON with generated SVG(s) and token usage metadata. Optional parameters: instructions (style guidance), references (reference images), n (number of outputs), temperature, max_output_tokens.

Vectorize an Image

Convert a raster image (PNG, JPG, etc.) to clean SVG format using AI.

Pricing: $0.30

{
  "method": "POST",
  "url": "https://pay.polymerlabs.org/proxy/https/quiver.x402endpoints.com/v1/svgs/vectorizations",

    "x-polymer-pay-api-key": "{{POLYMER_PAY_API_KEY}}"
  },
  "body": {
    "image": "https://example.com/logo.png"
  }
}

Response: JSON with vectorized SVG(s) and token usage metadata. The image field accepts a URL or base64-encoded image data. Optional parameters: auto_crop, target_size, n, temperature.

When to Use

• Logo generation — Create vector logos from text descriptions
• Icon design — Generate SVG icons for UI components
• Image vectorization — Convert raster images to scalable SVG format
• Illustration — Create AI-generated vector illustrations
• Brand assets — Generate scalable brand graphics programmatically

Best Practices

• Be specific in prompts — Describe colors, style, composition for better results
• Use instructions — Add style guidance via the instructions parameter for consistent output
• Provide references — Pass reference images to guide the AI's style
• Use vectorization for existing assets — Convert existing raster logos/icons to clean SVGs
• For errors — See @skills/polymer-pay-api-errors/SKILL.md for complete error code reference and troubleshooting
