MEX — WhatsApp's Internal GraphQL

All WhatsApp features (privacy, passkeys, profiles, usernames, integrity checks, …) run over MEX — WhatsApp's GraphQL-over-WebSocket protocol. Every method is available directly on your socket:

// Privacy
await sock.setPrivacySetting('LAST_SEEN', 'CONTACTS')   // UPPERCASE enums
await sock.updateGroupsAddPrivacy('contact_blacklist')   // lowercase IQ helpers also available

// Contact integrity — verify a JID is on WhatsApp before opening a chat
const result = await sock.contactIntegrityQuery(['[email protected]'])

// Username lookup
const user = await sock.findUserByUsername('baron')
// { jid: '[email protected]', contact: false } or null

// About text
const abouts = await sock.getTextStatusList(['[email protected]'])

// Error handling — all MEX methods throw Boom on failure
try {
    await sock.setPrivacySetting('LAST_SEEN', 'NONE')
} catch (err) {
    // err.output.statusCode: 400 bad request, 403 not available, 404 not found
}

See MEX.md for full documentation.

Anti-Ban System

Import from baron-baileys-v2/src/antiban.js:

const {
    AntiBan, RateLimiter, WarmUp, HealthMonitor,
    TimelockGuard, ReplyRatioGuard, ContactGraphWarmer,
    PresenceChoreographer, PostReconnectThrottle,
    RetryReasonTracker, LidResolver, JidCanonicalizer,
    MessageQueue, Scheduler, wrapSocket
} = require('baron-baileys-v2/src/antiban')

RateLimiter — throttle outbound messages

const limiter = new RateLimiter({
    maxPerMinute: 8,
    maxPerHour: 200,
    maxPerDay: 1500,
    minDelayMs: 1500,
    maxDelayMs: 5000,
    newChatDelayMs: 3000
})

const delay = await limiter.getDelay(jid, text)
if (delay === -1) return // blocked
if (delay > 0) await sleep(delay)

await sock.sendMessage(jid, { text })
limiter.record(jid, text)

WarmUp — gradual daily limit increase for new numbers

const warmup = new WarmUp({ warmUpDays: 7, day1Limit: 20, growthFactor: 1.8 })

if (!warmup.canSend()) return
await sock.sendMessage(jid, { text })
warmup.record()

console.log(warmup.getStatus())
// { phase: 'warming', day: 2, todayLimit: 36, todaySent: 12, progress: 28 }

HealthMonitor — detect ban risk

const health = new HealthMonitor({ autoPauseAt: 'high' })

sock.ev.on('connection.update', ({ connection, lastDisconnect }) => {
    if (connection === 'close') health.recordDisconnect(lastDisconnect?.error)
    if (connection === 'open') health.recordReconnect()
})

const status = health.getStatus()
// { risk: 'low'|'medium'|'high'|'critical', score, recommendation, stats }

if (health.isPaused()) return // auto-pauses at configured risk level

TimelockGuard — handle WA 463 reachout blocks

const guard = new TimelockGuard()

// Feed connection.update events
sock.ev.on('connection.update', ({ reachoutTimeLock }) => {
    if (reachoutTimeLock) guard.onTimelockUpdate(reachoutTimeLock)
})

// Check before sending to new contacts
const { allowed, reason } = guard.canSend(jid)
if (!allowed) return console.log(reason)

PresenceChoreographer — human-like typing simulation

const choreo = new PresenceChoreographer({
    enabled: true,
    typingWPM: 45,
    enableCircadianRhythm: true,
    timezone: 'Europe/Berlin'
})

const plan = choreo.computeTypingPlan(text.length)
await choreo.executeTypingPlan(sock, jid, plan)
await sock.sendMessage(jid, { text })

wrapSocket — apply all anti-ban layers at once

const { wrapSocket, resolveConfig, PRESETS } = require('baron-baileys-v2/src/antiban')

const wrappedSock = wrapSocket(sock, resolveConfig(PRESETS.SAFE))
// All outbound sendMessage calls are now automatically rate-limited,
// presence-simulated, and timelock-aware.
