# SmartFlow

> Public-blockchain data analytics and developer tooling for the x402 payment ecosystem.

## What is this?

SmartFlow analyses publicly available on-chain and x402 protocol-usage data and provides technical network analytics, and offers self-hosted developer software. Outputs are generic, non-personalised technical data — not investment advice, trading recommendations, or portfolio services.

## What SmartFlow does

- x402 network analytics — endpoint catalogue, reliability/liveness history, network-level usage metrics, and wallet-activity analytics, computed from publicly available on-chain data.
- Developer tooling — self-hosted developer software that builders run in their own environment.

## Products

- x402 endpoint audit — $199 USDC, one-off, signed report delivered within 48h.
  Order: POST https://verify.smartflowproai.com/audit/order with JSON {"target": "<endpoint url or 0x wallet>", "email": "<contact email>"}.
  The response is an order-bound HTTP 402 carrying an exact unique amount.
- Feeds API key — $49 USDC / 30 days (Pro) or $149 USDC / 30 days (Business).
  Order: POST https://verify.smartflowproai.com/keys/order with JSON {"email": "<contact email>", "plan": "pro" | "business"}.

Machine-readable definitions of both are in /.well-known/x402.
