# Read one diagram's evidence

> Page: https://docs.plotwork.dev/api/get-orgs-org-evidence-diagram. Index of every page: https://docs.plotwork.dev/llms.txt

One diagram drawn from code: its currency and controls, its check history on the default branch, and its drift episodes with the pull requests that resolved them.

`GET /orgs/{org}/evidence/diagram`

## TL;DR

| Question | Answer |
|---|---|
| What does it do? | Read one diagram's evidence. |
| What does it take? | `org` in the path, and `repository`, `name` in the query string. |
| What does it return? | Status 200 with a body of type [`EvidenceDiagramDetail`](https://docs.plotwork.dev/api/schemas.md#evidencediagramdetail). |
| What can go wrong? | `400` the query is not valid; `401` not signed in; `403` a plan without compliance evidence (plan.compliance_evidence_not_included); `404` no such organisation, the caller is not a member of it, or no check of the diagram is kept (evidence.diagram_not_found); `429` too many requests; `503` organisations are not set up on this server. Every failure uses the one error envelope. |

## What it does
