Fabric API (HTTP via Node/Python)

Use this skill when you need to read or write content in a user's Fabric workspace using the Fabric HTTP API (https://api.fabric.so).

This version avoids bash-only wrapper scripts. It ships cross-platform helpers:

• Node: {baseDir}/scripts/fabric.mjs (recommended)
• Python: {baseDir}/scripts/fabric.py

Critical gotchas (read first)

• There is no POST /v2/notes endpoint in the bundled OpenAPI spec. To create a “note”, use POST /v2/notepads.
• Most create endpoints require parentId:
  • A folder UUID or one of: @alias::inbox, @alias::bin
• Notepad creation requires:
  • parentId
  • and either text (markdown string) or ydoc (advanced/structured)
• tags must be an array of objects, each item either:
  • { "name": "tag name" } or { "id": "\x3Cuuid>" }
  • Never strings, never nested arrays.
• Field name gotcha: the API schema uses name (not title). If the user says “title”, map it to name in requests.

When the user doesn’t specify a destination folder, default to:

• parentId: "@alias::inbox"

Setup (OpenClaw / Clawdbot)

This skill expects the Fabric API key in:

• FABRIC_API_KEY

OpenClaw config example (~/.openclaw/openclaw.json):

{
  skills: {
    entries: {
      "fabric-api": {
        enabled: true,
        apiKey: "YOUR_FABRIC_API_KEY"
      }
    }
  }
}

Notes:

• apiKey is a convenience for skills that declare primaryEnv; it injects FABRIC_API_KEY for the duration of an agent run.
• Don’t paste the API key into prompts, client-side code, or logs.

HTTP basics

• Base URL: https://api.fabric.so (override with FABRIC_BASE if needed)
• Auth header: X-Api-Key: $FABRIC_API_KEY
• JSON header (for JSON bodies): Content-Type: application/json

Convenience scripts (cross-platform)

Node helper (recommended)

node {baseDir}/scripts/fabric.mjs GET /v2/user/me

node {baseDir}/scripts/fabric.mjs POST /v2/notepads --json '{"name":"Test note","text":"Hello","parentId":"@alias::inbox"}'

Python helper

python3 {baseDir}/scripts/fabric.py GET /v2/user/me

python3 {baseDir}/scripts/fabric.py POST /v2/notepads --json '{"name":"Test note","text":"Hello","parentId":"@alias::inbox"}'

Notes:

• Both helpers print the response body on success.
• On HTTP errors (4xx/5xx), they print HTTP \x3Ccode> \x3Creason> to stderr and still print the response body, then exit non‑zero (similar to curl --fail-with-body).
• If you pass an absolute URL (https://...), the helpers do not attach X-Api-Key unless you explicitly pass --with-key.

Core workflows

1) Create a notepad (note)

Endpoint: POST /v2/notepads

Rules:

• Map user “title” → name
• Use text for markdown content
• Always include parentId
• If you’re debugging 400s, start minimal (required fields only), then add name, then tags.

Minimal create:

node {baseDir}/scripts/fabric.mjs POST /v2/notepads --json '{"parentId":"@alias::inbox","text":"Hello"}'

Create with a name:

node {baseDir}/scripts/fabric.mjs POST /v2/notepads --json '{"name":"Calendar Test Note","text":"Created via OpenClaw","parentId":"@alias::inbox"}'

Create with tags (correct shape):

node {baseDir}/scripts/fabric.mjs POST /v2/notepads --json '{"name":"Ideas","text":"# Ideas\\
\\
- First\\
- Second\\
","parentId":"@alias::inbox","tags":[{"name":"ideas"},{"name":"draft"}]}'

If you keep seeing tag validation errors, temporarily omit tags and create the notepad first.

2) Create a folder

Endpoint: POST /v2/folders

node {baseDir}/scripts/fabric.mjs POST /v2/folders --json '{"name":"My new folder","parentId":"@alias::inbox","description":null}'

3) Create a bookmark

Endpoint: POST /v2/bookmarks

node {baseDir}/scripts/fabric.mjs POST /v2/bookmarks --json '{"url":"https://example.com","parentId":"@alias::inbox","name":"Example","tags":[{"name":"reading"}]}'

4) Browse resources (list children of a folder)

Endpoint: POST /v2/resources/filter

Important:

• This endpoint’s parentId expects a UUID (not an alias).
• If you only have an alias, resolve it by listing resource roots and picking the inbox/bin folder ID.

node {baseDir}/scripts/fabric.mjs POST /v2/resources/filter --json '{"parentId":"PARENT_UUID_HERE","limit":50,"order":{"property":"modifiedAt","direction":"DESC"}}'

5) Search

Endpoint: POST /v2/search

Use search when the user gives a fuzzy description (“the note about…”).

node {baseDir}/scripts/fabric.mjs POST /v2/search --json '{"queries":[{"mode":"text","text":"meeting notes","filters":{"kinds":["notepad"]}}],"pagination":{"page":1,"pageSize":20},"sort":{"field":"modifiedAt","order":"desc"}}'

Error handling + retries (practical guidance)

• 400 Bad Request: schema validation. Re-check required fields, and that tags is [{name}|{id}] not nested.
• 401/403: auth/subscription/permission. Stop and report the error details; don’t brute-force.
• 404: wrong endpoint, wrong ID, or no access.
• 429: rate limiting. Back off (sleep + jitter) and retry reads. Avoid blind retries on create (you may create duplicates).
• 5xx: transient; retry with backoff.
