# notebin.ca > A Markdown note/text bin for creating, rendering, sharing, and managing notes. > Notes can be public or unlisted, expose rendered reading and raw Markdown URLs, > and are stored as text with owner metadata for visibility, moderation, and > lifecycle. Accounts, OAuth, and API keys are federated from pastebin.ca. ## How it works - Create a note from Markdown using JSON, text/markdown, or multipart/form-data; title and description are optional metadata, and signed-in authors may publish public notes. - Public note URLs render Markdown for readers; raw Markdown is available at the note's raw URL. Owners can list, inspect, and delete their notes. - Editor helper endpoints preview Markdown and convert edited HTML back to Markdown; the OpenAPI document covers the stable REST create/list/read/delete contract. ## Developer docs - [Developer guide](https://notebin.ca/docs): REST API, MCP, OAuth, and discovery. - [OpenAPI 3.1 spec](https://notebin.ca/api/v1/openapi.json): the full REST contract. - [MCP server](https://notebin.ca/mcp): Model Context Protocol endpoint for AI agents. - [Agent card](https://notebin.ca/.well-known/agent.json): machine-readable capabilities. - [MCP discovery](https://notebin.ca/.well-known/oauth-protected-resource/mcp): protected-resource metadata. ## API summary - POST https://notebin.ca/api/v1/notes — create a Markdown note (scope note:create). JSON {markdown,title,description,visibility}, text/markdown, or multipart/form-data. - GET https://notebin.ca/api/v1/items/{id} — read note metadata and Markdown where visible (scope note:read for owner API-key reads). - GET https://notebin.ca/api/v1/account/items — list your notes (scope note:read); filters include q. - DELETE https://notebin.ca/api/v1/items/{id} — delete one of your notes (scope note:delete). ## Authentication - Account API keys are minted on https://pastebin.ca and audience-bound to https://notebin.ca. - Send them as: Authorization: Bearer pbca_live_… - OAuth 2.1 + PKCE (with optional DPoP) is available for interactive MCP clients; pastebin.ca is the authorization server. ## Policy - Anonymous notes are unlisted; signed-in authors may create public notes when allowed. - Notes may be moderated or removed for abuse, and owner-only fields expose state needed by management clients. - Privacy: https://notebin.ca/privacy - Report abuse at https://notebin.ca/abuse. - The governing family policy lives at https://pastebin.ca/privacy, https://pastebin.ca/terms, and https://pastebin.ca/abuse.
