# Introduction

> Search email delivery logs, retrieve sender profiles, query alerts, and request sender delisting with the MailChannels Log Search API.

The Log Search API gives you programmatic access to [email delivery logs](/outbound/log-search),
[sender profiles](/outbound/sender-profiles), and [alerts](/outbound/monitors-alerts).
You can also request sender delisting through the remediation endpoint.
Use it to investigate delivery issues, monitor sender activity, and build these capabilities into
your own control panel or support tools.

## Base URL

Use `https://api.mailchannels.net/outbound/v1` as the base URL for all API requests.
All requests must use HTTPS.

## Authentication

Include your Outbound Filtering API key in the `X-API-KEY` header with every request.

## Rate limits

The API allows up to 100 queries per second per customer. Queries that exceed this limit may
receive a `503 Service Temporarily Unavailable` response.

## Pagination

`POST /search` returns 20 results by default. Use the `count` query parameter to request up to
100 results per page. Use `start_at` to set the offset, starting at 0. To fetch the next page,
increase `start_at` by `count`.

The API rejects requests with a `400 Bad Request` response if `start_at + count` exceeds 9,999.
To retrieve more results, split your search into smaller date ranges using `start_date` and
`end_date`, and paginate through each range.

## Time range

By default, `POST /search` searches the last 3 days of data. To search a different date range,
include both `start_date` and `end_date` in the request body, using the `YYYY-MM-DD` format.
