# Heron

> AI-visibility (GEO) audits. See how AI search engines see your site.

Heron measures how likely a web page is to be cited by AI search engines
(ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews) and returns a
prioritized plan to improve it. Built for humans (web UI) and for autonomous
agents (machine-to-machine over the x402 payment standard).

## How it scores
Six weighted dimensions: AI crawler access, llms.txt presence, structured data
(schema.org), content depth, E-E-A-T / trust signals, and LLM-judged citability.
Output: a 0-100 GEO score plus concrete fixes.

## Use it
- Free instant score (humans + agents): POST /api/audit  body {"url": "..."}
- Full report ($39 USDC on Base): https://heronapp.io
- Agent endpoint (x402, pay-per-audit): GET /agent/audit?url=...
- Name-your-price (above floor): GET /agent/quote?url=...&bid=NN
- Machine-readable service manifest: /.well-known/agent.json
- Note for agent clients: send a non-empty User-Agent header (any identifying value).
