> Clean residential SOCKS5/HTTP proxies. No KYC. Crypto checkout. Encrypted backend.

## What this service does
Sells residential SOCKS5 and HTTP CONNECT proxies with global geo-targeting
(country/city/region). Buy with Bitcoin (no KYC). Instant activation.

## Why agents use Clean Proxys
Agents that scrape, crawl, or access geo-restricted or rate-limited endpoints
fail fast on datacenter-flagged or shared IPs. Clean Proxys issues clean
residential IPs (not VPN, not datacenter) that bypass IP-based blocks, with
per-country/city targeting and sticky or rotating sessions. One POST provisions
a working proxy — no KYC, Bitcoin billing, programmatic end-to-end.

## Key facts
- Protocol: SOCKS5 (port {PROXY['socks_port']}), HTTP CONNECT (port {PROXY['http_port']})
- Auth: per-user username + password
- Geo: country, city, region targeting
- Sessions: sticky or rotating
- Billing: pay-per-GB, Bitcoin (BTCPay)
- Signup: username + password only (no email, no KYC)

## MCP (for agent clients)
- Streamable HTTP MCP server: {SITE_HOST}/mcp
- Tools: get_info, list_plans, buy_proxy, get_order_status, list_dedicated_locations

## API
- OpenAPI spec: {SITE_HOST}/openapi.json
- GET /api/v1/info -> service info (JSON)
- GET /api/v1/plans -> residential GB plans (JSON)
- POST /api/v1/proxy -> one-call purchase (JSON: plan_id, country, city, username, password) -> creds + BTCPay checkout URL
- GET /api/v1/order/<id> -> payment status (pending/paid)
- GET /api/v1/dedicated/locations?product=9 -> ISP dedicated locations (JSON)
- GET /api/v1/dedicated/locations?product=3 -> datacenter dedicated locations (JSON)
- Human signup: {SITE_HOST}/signup
- Dedicated IPs: {SITE_HOST}/dedicated (datacenter $1.80/30d + ISP $4/30d resold at markup)

## Connect (after signup + top-up)
