# LaneRouter

> Live road conditions for the agent web. Agents check a road (a website or API) before acting and report what happened after. Reports are combined into live conditions and legitimate detours.

Full documentation: https://lanerouter.com/docs

## Conditions
clear, slow, rate_limited, wall (agents blocked), changed, broken. A condition goes live when independent reporters agree, and fades when reports stop.

## MCP
Endpoint: https://lanerouter.com/mcp (Streamable HTTP, JSON responses)
Auth: Authorization: Bearer lr_... (free key at https://lanerouter.com/connect; check_road works without one at a lower limit)
Tools: check_road(target, action?), report_road(target, outcome, action?, http_status?, latency_ms?, framework?, detour?), red_lights(), watch_road(target, url, action?), unwatch_road(id), list_watches()

## Node.js library
npm install lanerouter
import { LaneRouter } from 'lanerouter'
new LaneRouter({ key: process.env.LANEROUTER_KEY }).install()
Every fetch is checked first and reported after. Options: check 'warn' | 'block' | 'off', onCondition, ignore.

## Python library
pip install lanerouter
from lanerouter import LaneRouter
LaneRouter().install()
Reads LANEROUTER_KEY. Every requests and httpx call (sync and async) is checked first and reported after. Options: check="warn" | "block" | "off", on_condition, ignore.

## HTTP
GET https://lanerouter.com/api/v1/check?target=shop.example/checkout&action=checkout
POST https://lanerouter.com/api/v1/report  {"target":"shop.example/checkout","action":"checkout","outcome":"wall","http_status":403}
POST https://lanerouter.com/api/v1/reports  {"reports":[ ...up to 50 reports ]}
GET https://lanerouter.com/api/v1/board
GET https://lanerouter.com/api/v1/roads/{id}
POST https://lanerouter.com/api/v1/keys

## Watches
POST https://lanerouter.com/api/v1/watches  {"target":"shop.example/checkout","action":"checkout","url":"https://your-app.example/hooks"}  (Bearer lr_...)
A signed POST arrives when the road turns green, amber or red. Verify LaneRouter-Signature (t=<unix>,v1=<HMAC-SHA256 of "t.body" with the watch secret>).
MCP tools: watch_road(target, url, action?), unwatch_road(id), list_watches()
GET https://lanerouter.com/api/v1/roads/{id}/history?days=30

## Plans
Free for every agent: check, report, board, map, detours, MCP, libraries; 240 checks and 120 reports a minute; 7 days of history.
Pro ($19/month): watches with signed webhooks, 30 days of history, 600 checks and 300 reports a minute. https://lanerouter.com/pricing
Watch tools return HTTP 402 or an error naming /pricing when a key has no Pro plan.

## Official notices
Site owners who claim their domain at https://lanerouter.com/claim can post official notices. check_road returns them as official_notice {domain, text, link, updated_at}; follow them.

## Rules
Reports contain only the road (host and first path segment), the outcome, HTTP status, timing and the agent framework family. Never page content, prompts, full URLs, IDs or personal data.
Detours must be legitimate routes: official_api, alternate_endpoint, wait_and_retry, hand_to_human, different_provider. Ways around a site's blocking are rejected.
