# Discourse (meta.discourse.org): spec vs live

Part of [We checked 13 public APIs against their own OpenAPI specs. 9 had hard mismatches.](https://apidrifter.com/research/public-api-spec-drift-2026-11/).

## Summary

- Spec: https://docs.discourse.org/openapi.json (OpenAPI 3)
- Base URL: `https://meta.discourse.org`
- Run: 2026-10-30, read-only GET requests, no credentials
- Coverage: 95 operations in the spec, 21 requests sent, 13 successful, 21 operations observed
- Hard violations: 106 distinct schema locations
- Reviewer note: Confirmed: category custom_fields holds plugin keys the spec forbids; topic tags are objects where the spec says strings; permission is null. The spec is generated from test fixtures and lags the live site.

## Hard violations (106)

A typed client generated from the spec would break on these.
