# Pull Request Cost for Coding Agents

> What each pull request cost in coding-agent usage, across every session and every contributor that worked on it.

Open **Pull requests** at [/me/pull-requests](https://app.langwatch.ai/me/pull-requests), or in the sidebar of a project that receives coding-agent telemetry.

<Frame caption="The pull requests list. Status is read live from GitHub, and Token cost sums every session that worked on the branch. A branch with no pull request yet keeps its row.">

## Prerequisites

Two things join a session to a pull request:

1. The session reports the repository and branch it works on. This happens automatically once your agent is set up; [Repository and PR attribution](/docs/coding-agents/repository-and-pr-attribution) explains the mechanics.
2. The organization has GitHub connected, under **Settings → Integrations**. LangWatch maps each reported branch to the pull requests whose head is that branch, and reads pull request status live from GitHub.

## The list

| Column           | What it shows                                                  |
| ---------------- | -------------------------------------------------------------- |
| **Pull request** | Repository and number.                                         |
| **Title**        | The pull request's title.                                      |
| **Status**       | Open, merged, closed or draft, read live from GitHub.          |
| **Last update**  | The last coding-agent activity on the pull request's branches. |
| **Models**       | The models the sessions used.                                  |
| **Tokens**       | Total tokens across every attributed session.                  |
| **Token cost**   | The summed cost of those sessions.                             |

Cost is priced over the pull request's whole lifetime, not the period you selected: a pull request opened three weeks ago shows everything spent on it since, across every contributor. That is the number to compare against what the change was worth.

## Pull request detail

Click a row for the breakdown:

* **Contributors**: who spent what on this pull request. A contributor is a person, or a project when the work ran through a team project.
* **Models**: the token and cost split per model.
* **Sessions**: every session that drove the branch, each opening into its [terminal replay](/docs/coding-agents/sessions#terminal-replay).

## Read it over the API

`GET /api/coding-agent/pull-request-usage` returns the same rollup, filterable by project, user and agent. See [Get pull request coding agent usage](/docs/api-reference/coding-agents/get-pull-request-coding-agent-usage).

**Also check:** [Repository and PR attribution](/docs/coding-agents/repository-and-pr-attribution) for how sessions reach pull requests, and what happens with work done outside any checkout.
