Rate Limits & Quotas — WhatsApp Profile API

How request quotas, burst rate limits, and overage billing work across every pricing tier.

Monthly quota per tier

TierMonthly quotaOverageHard limit
BASIC50 requestsYes — blocks at 50
PRO10,000 requests$0.010 / requestNo
ULTRA50,000 requests$0.008 / requestNo
MEGA500,000 requests$0.005 / requestNo
Pay-As-You-GoCredit-basedYes — blocks at 0 credits

Burst / per-second limits

A per-tier burst limit prevents abuse from a single key:

TierDefault burst (req/sec)
BASIC2
PRO2
ULTRA2
MEGA4

MEGA customers needing sustained higher burst can request a custom limit through the dedicated account manager.

Rate-limit headers

Every response includes lowercase headers (RapidAPI convention) for monthly quota tracking:

x-ratelimit-requests-limit:     60000
x-ratelimit-requests-remaining: 59999
x-ratelimit-requests-reset:     2591983   # seconds until reset

429 Too Many Requests

Burst-limit violation (requests too close together) returns HTTP 429 with a short error body:

HTTP/1.1 429 Too Many Requests

{
  "error": "Requests must be at least 0.5 seconds apart"
}

The 0.5 seconds apart wording reflects the default minIntervalSeconds on most plans (= 2 req/sec). Inspect /api-key-stats → roleInfo.minIntervalSeconds for your plan's exact value.

Check your own quota

The proxy exposes GET /api-key-stats — call it any time to read the live counter:

  "role": "pro_60",
  "status": "active",
  "requestLimit": 60000,
  "requestRemaining": 59999,
  "requestReset": 2591982,
  "resetAt": "2026-05-27T02:24:56.708Z",

  "requestCountMonth": 1,

  "roleInfo": {
    "name": "pro_60",
    "maxMonthlyUsage": 60000,
    "minIntervalSeconds": 0.5
  }
}

Caching policy

Profile data is cached server-side. Repeat lookups for the same number within the cache window are served from cache. To force a fresh lookup, append ?forceBypassCache=1 to /number/{number} — the fresh request still counts against quota.
