name: openwhispr-api description: Use this skill when building integrations with the OpenWhispr REST API, calling OpenWhispr endpoints, managing notes/folders/transcriptions programmatically, or connecting to the OpenWhispr MCP server. Covers authentication, all V1 endpoints, pagination, rate limits, error handling, and the remote MCP server.
OpenWhispr API v1
Use this reference when making requests to the OpenWhispr REST API. All endpoints are under the V1 path and require API key authentication.
Authentication
Pass the API key as a Bearer token in the Authorization header on every request.
Authorization: Bearer owk_live_YOUR_KEY
Generate keys from the OpenWhispr desktop app under Settings > API Keys. Keys start with owk_live_ and are shown once at creation.
Scopes
Each key has scoped permissions. The API rejects requests missing the required scope with 403 Forbidden.
| Scope | Grants |
|---|---|
notes:read | List, get, and search notes. List folders. |
notes:write | Create, update, and delete notes. Create folders. |
transcriptions:read | List and get transcriptions. |
usage:read | Read usage statistics. |
Base URL
https://api.openwhispr.com/api/v1
Response Envelope
Wrap all responses in a consistent envelope.
Single resource:
{ "data": { "id": "uuid", "title": "My note", ... } }
Paginated list:
{
"data": [{ ... }, { ... }],
"has_more": true,
"next_cursor": "2026-04-15T10:30:00.000Z"
}
Error:
{ "error": { "code": "not_found", "message": "Note not found" } }
Error Codes
| HTTP Status | Code | Meaning |
|---|---|---|
| 400 | validation_error | Invalid request body or query params |
| 401 | invalid_api_key | Missing, malformed, expired, or revoked key |
| 403 | forbidden | Key lacks required scope |
| 404 | not_found | Resource does not exist or belongs to another user |
| 405 | method_not_allowed | Wrong HTTP method |
| 409 | conflict | Duplicate resource (e.g. folder name) |
| 429 | rate_limited | Rate limit exceeded — check Retry-After header |
| 500 | internal_error | Server error |
Rate Limits
Enforced per API key with minute and daily windows. Search requests cost 5x against the rate limit.
| Plan | Per Minute | Per Day |
|---|---|---|
| Free | 30 | 1,000 |
| Pro | 120 | 10,000 |
| Business | 300 | 50,000 |
Response headers on every request:
| Header | Description |
|---|---|
X-RateLimit-Limit | Max requests per minute |
X-RateLimit-Remaining | Remaining in current window |
X-RateLimit-Reset | Unix timestamp when window resets |
Retry-After | Seconds to wait (only on 429) |
Pagination
List endpoints use cursor-based pagination. Pass the next_cursor value from a previous response as the cursor query parameter to fetch the next page. When has_more is false, there are no more results.
GET /notes/list?limit=50&cursor=2026-04-15T10:30:00.000Z

MCP Server
For AI assistant integration (Claude, Cursor, VS Code), connect to the remote MCP server at:
https://mcp.openwhispr.com/mcp
Pass the API key via Authorization: Bearer header. All V1 endpoints are available as MCP tools. The server uses Streamable HTTP transport (stateless, no sessions).
Claude Code
claude mcp add openwhispr --transport http https://mcp.openwhispr.com/mcp \
--header "Authorization: Bearer owk_live_YOUR_KEY"
Cursor / VS Code
{
"mcpServers": {
"openwhispr": {
"url": "https://mcp.openwhispr.com/mcp",
"headers": { "Authorization": "Bearer owk_live_YOUR_KEY" }
}
}
}
