    Rate Limits & Quotas

    BounceCheck limits usage by monthly quota, not by requests-per-second. There is no per-second throttle on the authenticated API.

    Monthly plan quotas

    Plan Verifications / month
    FREE 50
    STARTER 5,000
    PRO 20,000

    Each single verify, disposable check, or bulk-processed address consumes one unit. A bulk upload is rejected up front if its size exceeds your remaining quota.

    When the quota is reached

    The API returns HTTP 429 with a detail message. Upgrade your plan or wait for the monthly reset. FREE plans reset automatically each month.

    Public (unauthenticated) endpoints

    The landing-page tools are limited per IP per day and protected by reCAPTCHA:

    Endpoint Limit
    POST /verification/public/verify 20 / day / IP
    POST /verification/disposable-check/public 10 / day / IP

    For anything beyond that, create a free account and use an API key.
