# List Portfolio Deadlines

> List deadlines computed from a portfolio’s trademark records

<Snippet file="portfolios/access.mdx" />

See [portfolio limits and references](/guides/portfolios) for current caps and
`external_ref` semantics.

## Overview

Computes deadlines on demand and returns a collection with `data`, `has_more`,
and `pagination.cursor`. Each row identifies its `trademark_id` and statutory
`rule_id`, with the deadline type, due date, and jurisdiction.

For a calendar file, use [Download Portfolio Calendar](/api-reference/portfolios/deadlines-ics).

## Query Parameters

Use `due_before` to bound the due date (default: approximately 24 months from now),
`type` to filter a deadline type, and `limit` (default 20, maximum 100) plus the
returned opaque `cursor` to page through results.

`due_before` must be an ISO 8601 calendar date, `YYYY-MM-DD` (for example
`2027-06-30`). Anything else — a bare year, a datetime, free text — is rejected
with 400 `validation_error`.

## Errors

A `due_before` that is not `YYYY-MM-DD` returns 400 `validation_error`.

More than **5,000 marks in this portfolio** returns 422 `portfolio_too_large`.
Split it into smaller portfolios and request each separately. A narrower date or
type filter does not avoid this cap, and the ICS download has the same cap.
