ECHO — Obsidian Local REST API Reference

Server: https://echoapi.alwisp.com (reverse proxy → backend Obsidian Local REST API) Auth header: Authorization: Bearer 241265fbe6830934a9a4ad3e69335f64a42153b663aa5b0017cb1ea1217b2bab The endpoint has a valid TLS certificate — -k is not required. Paths address the vault at its root.

Reading Files

# Read any file by vault path
curl -s \
  -H "Authorization: Bearer 241265fbe6830934a9a4ad3e69335f64a42153b663aa5b0017cb1ea1217b2bab" \
  "https://echoapi.alwisp.com/vault/_agent/context/current-context.md"

Returns raw file content (text/markdown). On 404, the file does not exist.

# Read a specific heading's content only
curl -s \
  -H "Authorization: Bearer 241265fbe6830934a9a4ad3e69335f64a42153b663aa5b0017cb1ea1217b2bab" \
  "https://echoapi.alwisp.com/vault/_agent/memory/semantic/operator-preferences.md/heading/Operator"

Nested headings: separate levels with :: (URL-encode spaces as %20):

/vault/path/to/note.md/heading/Work%3A%3AMeetings

Listing Directories

# List contents of a directory (trailing slash required)
curl -s \
  -H "Authorization: Bearer 241265fbe6830934a9a4ad3e69335f64a42153b663aa5b0017cb1ea1217b2bab" \
  "https://echoapi.alwisp.com/vault/_agent/sessions/"

Returns JSON: { "files": [...], "folders": [...] }.

Appending Content (POST)

POST appends to the end of an existing file. Creates the file if it doesn't exist.

cat > /tmp/obs_entry.md << 'OBSEOF'
- 2026-06-05: your entry here
OBSEOF

curl -s -X POST \
  -H "Authorization: Bearer 241265fbe6830934a9a4ad3e69335f64a42153b663aa5b0017cb1ea1217b2bab" \
  -H "Content-Type: text/markdown" \
  --data-binary @/tmp/obs_entry.md \
  "https://echoapi.alwisp.com/vault/inbox/captures/inbox.md"

Creating or Overwriting Files (PUT)

PUT creates a new file or fully overwrites an existing one. Intermediate directories are created automatically.

Patching a Specific Section (PATCH)

PATCH edits inside a file without rewriting it. Target and operation are set via headers.

Append under a heading

Heading targets must be the FULL heading path, ::-delimited from the top-level heading. A bare subheading name returns 400 invalid-target (errorCode 40080). Example: ## Fact / Pattern nested under # Operator Preferences → Target: Operator Preferences::Fact / Pattern. Percent-encode non-ASCII characters (e.g. H%C3%A9llo); spaces are fine.

cat > /tmp/obs_patch.md << 'OBSEOF'
Jason prefers concise status updates — lead with the decision.
OBSEOF

curl -s -X PATCH \
  -H "Authorization: Bearer 241265fbe6830934a9a4ad3e69335f64a42153b663aa5b0017cb1ea1217b2bab" \
  -H "Operation: append" \
  -H "Target-Type: heading" \
  -H "Target: Operator Preferences::Fact / Pattern" \
  -H "Content-Type: text/markdown" \
  --data-binary @/tmp/obs_patch.md \
  "https://echoapi.alwisp.com/vault/_agent/memory/semantic/operator-preferences.md"

Discover heading / block / frontmatter targets

When unsure of the exact heading path, GET the note with the document-map Accept header:

curl -s \
  -H "Authorization: Bearer 241265fbe6830934a9a4ad3e69335f64a42153b663aa5b0017cb1ea1217b2bab" \
  -H "Accept: application/vnd.olrapi.document-map+json" \
  "https://echoapi.alwisp.com/vault/_agent/memory/semantic/operator-preferences.md"

Returns { "headings": [...], "blocks": [...], "frontmatterFields": [...] }. Copy the heading string verbatim into Target.

Replace a heading's content entirely

Same call with Operation: replace — e.g. to refresh a project's Project Name::Current status.

Prepend under a heading

Same call with Operation: prepend.

Patch a frontmatter field

curl -s -X PATCH \
  -H "Authorization: Bearer 241265fbe6830934a9a4ad3e69335f64a42153b663aa5b0017cb1ea1217b2bab" \
  -H "Operation: replace" \
  -H "Target-Type: frontmatter" \
  -H "Target: updated" \
  -H "Content-Type: application/json" \
  --data '"2026-06-05"' \
  "https://echoapi.alwisp.com/vault/projects/active/vault-foundation.md"

Searching

curl -s -X POST \
  -H "Authorization: Bearer 241265fbe6830934a9a4ad3e69335f64a42153b663aa5b0017cb1ea1217b2bab" \
  "https://echoapi.alwisp.com/search/simple/?query=weekly+review"

Returns an array of { filename, score, matches: [{ context, match }] }.

Deleting Files

curl -s -X DELETE \
  -H "Authorization: Bearer 241265fbe6830934a9a4ad3e69335f64a42153b663aa5b0017cb1ea1217b2bab" \
  "https://echoapi.alwisp.com/vault/archive/notes/old-note.md"

Only on explicit operator request. Deletion is destructive.

URL-Encoding Notes

Path separators (/) in the vault path are literal — do not encode them.
Spaces in filenames or heading targets in a URL: use %20.
Nested heading levels in a URL path: use %3A%3A for ::.
Heading text in the Target: header: the full heading path joined by :: (e.g. Operator Preferences::Fact / Pattern), no #; spaces are fine; percent-encode non-ASCII.
