Origin API

The docs are the source of truth. Do not name an endpoint, scope, event slug, header, or limit from memory. Where this file and the docs disagree, the docs win.

The docs live under https://cursor.com/docs/api/origin/. llms.txt is the index and links every section, endpoint, and webhook payload. openapi.yaml is the contract, and "Endpoint reference" explains its x-origin-* extensions. llms-full.txt is the whole reference in one file. changelog says what moved. For one question, start at llms.txt and fetch only the section that answers it. llms-full.txt and openapi.yaml are each several hundred kilobytes, too large to read into context whole. When you need all of them, as a porting brief does, save them locally if you can, outside any repository you are working in, search them for the section heading or annotation you need, and read only the matching part. Cite operationIds and section names.
