Create Temporary Mailbox

Create a new temporary email address. By default, a random email address is generated. You can customize the email username, domain, or domain type by providing the appropriate parameters in the JSON request body.

パラメータ 4
パラメータ 場所 種類 ステータス 説明
username body string 任意
Custom mailbox username prefix (subject to plan custom username permissions).
デフォルト: Randomly generated
domain body string 任意
One of the allowed domains returned by GET /domains.
デフォルト: Default allowed domain
lifetime body string 任意
Mailbox duration: 10m, 1h, 2h, 1d, 1w, 1m, or unlimited (also accepts mailbox_lifetime or email_lifetime).
デフォルト: Plan default lifetime
provider body string 任意
Mailbox provider: standard, gmail_alias, or outlook_alias.
デフォルト: standard
Optional body parameters: username (custom username if allowed by plan), domain (allowed domain, e.g. example.com), lifetime (allowed values: 10m, 1h, 2h, 1d, 1w, 1m, unlimited), provider (standard, gmail_alias, outlook_alias). Omit lifetime, or leave it empty, to use the Default Email Lifetime configured for your current monthly/yearly plan. Send a permitted lifetime such as 1h to override that default. Unlimited is used only when configured as the plan default or explicitly requested and permitted. The body parameters mailbox_lifetime and email_lifetime are also accepted; the first non-empty value wins in this order: lifetime, mailbox_lifetime, email_lifetime. Invalid or disallowed values return HTTP 422 instead of silently selecting a default.

Rate Limits & Quotas

Monitor real-time request budgets, rate limits, and account quotas without consuming credits.

GET https://v1.tempmailg.com/api/rate-limit
#

Rate Limit & Quota

Check your current rate limit and quota status without consuming any API usage. This endpoint is quota-free and does not deduct monthly API credits (abuse protection limit: 60 requests/min).

X-RateLimit-* describes the indicated request budget; X-Quota-* describes monthly and purchased capacity when available. X-Mailbox-RateLimit-* reports the separate mailbox creation/update budget. A mailbox-only rejection uses mailbox scope and its own retry window. Minute-limit rejections may omit quota information. Retry-After is included only for a timed retry; disabled access may require an account change. In this successful status response, data.limit, data.remaining and data.reset describe the account minute budget, not spendable credits. The data.quota object describes monthly allowance, credit balances and usage. The existing data.monthly_limit, data.monthly_remaining and data.purchased_credits fields remain aliases of the corresponding quota fields. A successful status check does not authorize another API operation. Operations still require enabled access, available quota and admission through all applicable limits. The quota snapshot does not promise capacity already reserved by an in-progress request.

レスポンス フィールド
フィールド 種類 説明
data.limit integer|string
Account requests-per-minute limit. The string unlimited denotes an unlimited minute budget; this is independent of monthly quota.
data.remaining integer|string
Remaining account minute-budget slots, or the string unlimited. A positive value does not mean that API credits remain.
data.reset integer
Seconds for the account minute window, not the monthly quota reset. Disabled or unlimited minute budgets can retain a nominal 60-second value; this does not promise access after waiting.
data.plan string
Current plan tag. The readable plan name is provided separately in data.quota.plan_name.
data.quota.enabled boolean
Whether global and plan/credit API access is enabled. This does not indicate remaining capacity or replace the user API switch.
data.quota.user_api_status boolean
Whether the user has enabled their User API switch. Operations require this switch as well as enabled access and available capacity.
data.quota.plan_name string
Readable name of the current plan.
data.quota.period string
Calendar-month usage period in YYYY-MM format, using the application timezone; not necessarily the subscription billing period.
data.quota.base_limit integer
Base monthly plan allowance. A value of -1 means unlimited.
data.quota.extra_requests integer
Additional monthly allowance granted for the current usage period; separate from purchased credits.
data.quota.monthly_limit integer
Base allowance plus current-period extra requests. A value of -1 means unlimited. Purchased credits are not included.
data.quota.monthly_remaining integer|null
Remaining finite monthly allowance, or null when monthly quota is unlimited. Null must not be interpreted as zero.
data.quota.used integer
Successful, counted API operations in the current usage period, including operations using credits. Status checks do not increase this value.
data.quota.purchased_credits integer
Current credit balance, including active plan bonus credits. Bonus credits must not be added to this balance a second time.
data.quota.bonus_credits integer
Active plan-bonus portion of the credit balance; a breakdown of purchased_credits, not additional capacity.
data.quota.direct_purchased_credits integer
Credit balance excluding the active plan-bonus portion. This value plus bonus_credits equals purchased_credits.
data.quota.remaining integer|null
Monthly remaining allowance plus the current credit balance, without double-counting bonuses. Null means unlimited monthly quota. Individual feature permissions and other request limits still apply.
data.quota.unlimited boolean
Whether monthly quota is unlimited. This does not make the account minute budget or other feature limits unlimited.
data.quota.usage_percent integer
Dashboard-compatible rounded percentage from 0 to 100: used divided by used plus remaining, multiplied by 100. It includes available credit capacity, so recharging can lower the percentage. It is 0 for unlimited quota or a zero-sized pool; it is not the minute rate-limit percentage or an access decision.
data.quota.reset_at string
ISO-8601 timestamp with timezone offset for the next calendar-month quota reset. This is not the subscription expiry date, and the monthly reset does not refill purchased credits.
