# Sent mail per hour

`GET /stats/sent-emails/hourly`

## Request

- Base URL: `https://api.primitive.dev/v1`
- URL: `https://api.primitive.dev/v1/stats/sent-emails/hourly`
- Auth: HTTP bearer

Sent mail per UTC hour over the last `days` days, by outcome: delivered, bounced (including agent failures, wait timeouts and unknown endings) and denied by a send gate. Sends still in flight are not counted until they end. Hours with no mail are left out. Needs mail:read. Counts only the mail the credential may read: a credential narrowed to some addresses counts the mail its scope admits.

## Query parameters

- `days` integer: How many days back, from 1 to 31; defaults to 8.

## Response `200`

Sent mail per hour

- object
  - `success` true, required
  - `data` object[], required
    - `hour` string, date-time, required
    - `delivered` integer, required
    - `bounced` integer, required
    - `denied` integer, required

## Other responses

- `400`: Invalid request parameters
- `401`: Invalid or missing API key
- `403`: Authenticated caller lacks permission for the operation
- `429`: Rate limit exceeded. The `ratelimit-*` headers describe the limiter that rejected this request, with its own limit and window, not the API budget that successful responses report. A limiter that reports only a wait sends `Retry-After` alone.
