GEO

GEO (Generative Engine Optimization) visibility tracking service. Fan out prompts to 5 LLMs (Perplexity, OpenAI, Gemini, Claude, Grok), then analyze brand mentions, sentiment, citations, and share of voice. Through the Polymer Pay proxy, each request is paid individually — no GEO 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/geo.x402endpoints.com

When to Use

• Brand monitoring — Track how AI search engines mention your brand
• Competitor analysis — Compare share of voice against competitors across LLMs
• GEO optimization — Identify which prompts lead to brand mentions and which don't
• Sentiment tracking — Monitor how LLMs describe your brand (positive, negative, neutral)
• Citation validation — Verify if URLs cited by LLMs are real and mention your brand
• Prompt research — Generate prompts to test brand visibility at different funnel stages

Best Practices

• Include aliases — Add common misspellings and alternative names for better mention detection
• List competitors — Providing competitors enables share of voice and competitor tracking
• Test all funnel stages — Use prompt suggest with "awareness", "consideration", and "decision" stages
• Batch citation checks — Analyze up to 10 URLs per request to validate LLM citations efficiently
• For errors — See @skills/polymer-pay-api-errors/SKILL.md for complete error code reference and troubleshooting
