Post file format on /v1/fs

Over the /v1/fs API, a post is a markdown file: a block of frontmatter, the title as a # heading, then the body. This page is the reference for that file and for its name. For how mentions are written, see Mention syntax.

Frontmatter

A GET of a post's file returns the frontmatter, then the title and the body:

---

isDraft: true                           # only if a draft
comments: 3
mentions: [Maya, Jun]

# Launch checklist

The body, with mentions written as @Maya.

The rules:

• Times are ISO-8601 strings in UTC.
• Lists are written [a, b]. A value with special characters is quoted, as a JSON string.
• An optional field is left out when it has no value. comments and mentions are always there; with no mentions, mentions is [].
• The parser accepts # comments and blank lines in the frontmatter.

What you send

When you write a post, frontmatter is optional.

• The title is the first line, if it's a # heading. Otherwise it's a frontmatter title:. A file with neither answers 422. A title can be up to 200 characters.
• The body is everything after the title.
• scheduledFor is the only frontmatter field sfora reads from what you send. Put a draft under drafts/ with a scheduledFor (an ISO-8601 time, or milliseconds since the epoch), and sfora publishes it then. Every other field is set by sfora.

Mentions in the body can be in the canonical form or bare names; see Mentions.

File names

sfora names a post's file YYYY-MM-DD-<slug>.md:

• The date is the publish date, the first ten characters of publishedAt. A draft uses the day it was created.
• The slug is the title in lower case, with accents removed, every run of other characters turned into one hyphen, and no hyphen at either end. An empty title gives untitled.

So "Launch checklist", published on 6 October 2026, is 2026-10-06-launch-checklist.md.

Finding a post by its name

When you read or write a path, sfora takes the name without .md and without a leading date, and looks for a post whose title has that slug. If none has, it looks for a post with that id. If several posts have the same slug, the most recently created one wins.

The name you send is matched as written. To reach a post you published as "Launch checklist", use launch-checklist.md or 2026-10-06-launch-checklist.md. A name that matches no post creates a new one, stored under the name sfora makes from its title. The answer to a write says that name in filename.
