# x402watch
> Wash-filtered intelligence layer for the x402 ecosystem — free public dashboard, daily CC0 datasets, x402-native paid API, and a remote MCP server.

## What is x402watch
Public x402 dashboards count transactions. **x402watch classifies them.**
Every active buyer wallet is tagged with one of eight labels — `organic_user`, `self_test`, `developer`, `suspected_wash`, `ai_agent`, `analytics_bot`, `exchange_user`, or `verifier` — using cohort signals + vanity clustering. Real-volume reporting excludes the synthetic categories, so service rankings reflect actual demand instead of self-funded noise.
## 4-Axis Differentiation
1. **Wash filter** — 8-label buyer classification, cohort signal detection (uniform_amount, coordinated_start, uniform_tx_count, time_burst), strict + broad vanity clustering, conservative developer label.
2. **Free public data** — every label, every benchmark. Daily CC0 snapshots in [`printmoneylab/x402watch-data`](https://github.com/printmoneylab/x402watch-data).
3. **AI-native** — public REST API, x402-native paid endpoints, [llms.txt](https://x402.printmoneylab.com/llms.txt), [OpenAPI spec](https://api.x402.printmoneylab.com/openapi.json), [RSS](https://x402.printmoneylab.com/feed.xml), [/.well-known/x402](https://x402.printmoneylab.com/.well-known/x402), and an MCP server.
4. **Coverage** — 36,000+ services indexed across **Base, Solana, Polygon, and Arbitrum**.
## Quick Start
### Free API
```bash
curl https://api.x402.printmoneylab.com/api/v1/landing-stats
curl https://api.x402.printmoneylab.com/api/v1/categories
curl 'https://api.x402.printmoneylab.com/api/v1/services?search=ai'
```
Rate limit: 60 req/hour per IP. No API key. CC0-licensed.
### MCP server (one command)
```bash
smithery mcp add bakyang2/x402watch
```
Or add to any MCP client manually (Claude Desktop, Cursor, Cline):
```json
{
"mcpServers": {
"x402watch": {
"transport": "streamable-http",
"url": "https://api.x402.printmoneylab.com/mcp"
}
}
}
```
### Paid endpoint (x402)
```python
import asyncio, os
from eth_account import Account
from x402 import x402Client
from x402.mechanisms.evm.exact import ExactEvmClientScheme
from x402.http.clients.httpx import x402HttpxClient
async def main():
acct = Account.from_key(os.environ["PRIVATE_KEY"])
payer = x402Client()
payer.register("eip155:8453", ExactEvmClientScheme(acct))
async with x402HttpxClient(payer, base_url="https://api.x402.printmoneylab.com") as c:
r = await c.post("/api/v1/wash/check", json={"address": "0x..."})
print(r.json()["label"])
asyncio.run(main())
```
The 402 round-trip pays USDC on Base mainnet via the CDP facilitator, retries with the signed payment header, and returns 200 with the data — no signup, no API keys.
## API Endpoints

## MCP Tools
Listed on the [official MCP Registry](https://registry.modelcontextprotocol.io/v0/servers?search=printmoneylab) as `io.github.printmoneylab/x402watch`. Streamable-http at `https://api.x402.printmoneylab.com/mcp`. Five read-only tools:
| Tool | What it returns |
| --- | --- |
| `x402_get_categories` | All 33 categories with services count, 24h volume, real-volume %, label distribution |
| `x402_get_service` | One service's full record: stats, 30-day daily volume, top buyers, label mix |
| `x402_check_wash` | Aggregate wash-report dataset (per-address analysis is the paid `POST /wash/check` endpoint) |
| `x402_search_services` | Search 36k+ services with filters (category, chain, sort, page) |
| `x402_get_trends` | 24h trends: new services, hot services, category volume movers |
## Architecture

| Hosting | Oracle ARM (backend, free tier) + Vercel (frontend) + Cloudflare DNS |
## Methodology
Open, version-controlled, deterministic from public on-chain data:
→ **<https://x402.printmoneylab.com/docs/methodology>**
Covers 8-label priority order, cohort signal thresholds, vanity-cluster math, and the conservative developer label. Source markdown lives in [`content/methodology.md`](content/methodology.md).

## Repository Layout
This repo holds the public Next.js site under `src/`. The methodology markdown lives in [`content/methodology.md`](content/methodology.md) and is rendered at [/docs/methodology](https://x402.printmoneylab.com/docs/methodology). The FastAPI backend and indexers live on a separate Oracle host.
## Contributing
Pull requests welcome. For methodology questions, dispute a label, or report a misclassified service, please open a [GitHub Issue](https://github.com/printmoneylab/x402watch/issues) — labels are deterministic and reproducible from public on-chain data, so we'll walk through the signals that triggered the classification.
