Create or update an entry

Validated against the collection's schema first: an invalid field is a 400 naming the field, and nothing is written. A new entry created through the API starts as a draft when the collection has a draft field. One history entry.

PUT/v1/sites/{site_id}/content/{collection}/{slug}

Requires sites:write. Costs no credits. Changes the draft only. Visitors see nothing until you publish.

An invalid field is refused with 400 and the field’s name, and nothing is written. A new entry starts as a draft when the collection has a draft field, so a person decides to show it.

Send create_only: true to refuse instead of overwriting an existing entry, or expected_hash to overwrite only the version you read.

  • fetchRead one page in full, as Markdown.
  • list_pagesSee every page in this documentation.

Query these docs over HTTP

The same tools also work as plain web requests. Use this for scripts, or for any tool that does not support MCP. There is one endpoint per tool. Arguments go in the query string, and the answer comes back as JSON.

https://atelier201.com/docs/api/docs/search?query=custom+domain

Read the OpenAPI description. It is built from the same definitions as the tools, so it always matches what the endpoints do.
