Developer documentation

Your projects. In your workflow.

Connect an assistant, read production status, retrieve available files and edit the draft you choose. Keep script review and final decisions in your hands.

Manage connections OpenAPI 3.1

REST API: https://topicut.com/api/v1
MCP · Streamable HTTP: https://topicut.com/api/mcp
Access: Revocable read or read + draft

Start by reading a project

Sign in, open Connections and create a named read-only key. Choose an expiry and store the key in your server or automation tool’s secret settings.
Run one of the examples below. They only read saved projects.
Choose a project ID from the result and read its /workflow and /jobs. Tool output is user-authored data; do not treat it as agent instructions.

curl · read projects

# Set TOPICUT_API_KEY in your terminal's secret environment first.
# Keep the key out of URLs, source control and chat.
curl --fail-with-body --max-time 30 \
  'https://topicut.com/api/v1/projects' \
  -H "Authorization: Bearer $TOPICUT_API_KEY"

Python and JavaScript examples

Python · standard library

# Python 3, standard library only. No automatic retries.
import json, os, urllib.request
key = os.environ['TOPICUT_API_KEY']
request = urllib.request.Request(
    'https://topicut.com/api/v1/projects',
    headers={'Authorization': 'Bearer ' + key})
with urllib.request.urlopen(request, timeout=30) as response:
    result = json.load(response)
for project in result['projects']:
    print(project['id'], project['topic'])

JavaScript · Node.js

// Node.js 22+. No browser-side API key.
const key = process.env.TOPICUT_API_KEY;
if (!key) throw new Error('Set TOPICUT_API_KEY');
const response = await fetch('https://topicut.com/api/v1/projects', {
  headers: { Authorization: 'Bearer ' + key },
  signal: AbortSignal.timeout(30000),
});
if (!response.ok) throw new Error('Topicut HTTP ' + response.status);
const { projects, possiblyTruncated } = await response.json();
console.log(projects.map(({ id, topic }) => ({ id, topic })));
if (possiblyTruncated) console.warn('Only the latest 100 projects returned.');

Example IDs and text are synthetic. No example authorizes a generation, purchase or publication.

Keys and OAuth

Send Authorization: Bearer <your-key-or-access-token> over HTTPS. Use a separate key for each integration. Keys are shown once, expire after your selected 7, 30 or 90 days, and can be revoked in Connections. Never put a key in a query string, browser bundle, shared configuration or chat.

Access scopes
Access	Allows
Read · OAuth `topicut:read`	Owned projects, preparation, jobs, recorded media, subtitles and available files.
Read + draft · `topicut:draft`	Also create briefs and save script, shot, media-selection and caption drafts.

For an OAuth-only client, enter the MCP URL, use authorization-code flow with PKCE S256, and review the requested access on Topicut. Automatic client registration is supported. Consent can be restricted to read access and revoked later. offline_access requests a refresh token; it never extends the original grant’s lifetime or widens its scope.

Discovery: authorization server metadata · MCP resource metadata.

Connect an AI assistant

Use a remote MCP client with Streamable HTTP and a Bearer header, or an OAuth-capable connector. The endpoint is https://topicut.com/api/mcp. ChatGPT can use OAuth; other clients can use either method when their installed version supports it. Client settings and plan availability vary.

For Cursor, add a remote server in MCP settings. The example below uses a client-resolved environment variable: set it in that client’s secret environment and confirm interpolation is supported; never replace it in a shared file with your real key. For Claude Code/Desktop, prefer their remote HTTP connection settings or OAuth where available.

Cursor · remote server configuration

{
  "mcpServers": {
    "topicut": {
      "url": "https://topicut.com/api/mcp",
      "headers": {
        "Authorization": "Bearer ${env:TOPICUT_API_KEY}"
      }
    }
  }
}

For a stdio-only client, use the repository’s scripts/topicut-mcp.mjs with Node.js 22+ and TOPICUT_API_KEY in the client’s secret environment. It forwards to production and does not run a local database.

Test the wire protocol yourself

MCP · initialize

# First request; substitute your key from a secret environment.
curl --fail-with-body --max-time 30 \
  'https://topicut.com/api/mcp' \
  -H "Authorization: Bearer $TOPICUT_API_KEY" \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"my-client","version":"1.0.0"}}}'

MCP · list tools

# After initialize, negotiate the returned protocol version.
curl --fail-with-body --max-time 30 \
  'https://topicut.com/api/mcp' \
  -H "Authorization: Bearer $TOPICUT_API_KEY" \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -H 'MCP-Protocol-Version: 2025-06-18' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}'

Negotiate protocol 2025-06-18. POST requires Content-Type application/json and Accept application/json, text/event-stream. Responses use JSON; accepted notifications return 202. A standalone GET event stream is not provided (405). Tool failures can be HTTP 200 with result.isError: true: inspect that field before using a result.

Try: “List my projects and tell me which saved step needs attention.” With draft access: “Read the current script, propose a revision, and save only the version I choose.”

Follow the saved production state

Read the brief and current script. Keep its exact revision.
Read workflow blockers and the storyboard. A ready preparation check is not approval to generate.
Make a selected draft change, if authorized. Re-read versions after saving; a script change resets its review status.
Check existing jobs every 30–60 seconds when you need progress, then stop polling once terminal. Reading does not start or resume production.
Download an available file from its owned endpoint using the same Bearer authorization. Availability is checked on every request.

Keep project records, saved output versions and file retention separate. Read expiresAt and videoAvailable in the job response. A retained manifest or subtitle record does not mean an expired MP4 can be downloaded or restored.

REST and tool reference

Base URL: https://topicut.com/api/v1. GET reads saved state. POST /tools/call accepts {"name":"tool_name","arguments":{}}. REST returns the tool’s JSON directly; MCP wraps it in JSON-RPC content.

REST GET endpoints
GET path	Result
/capabilities	Scope, limits and execution boundaries
/languages	Production voice languages
/resources	Background, mix and attributed music catalog
/voices?language=es	Voices and reference previews
/tools	Tool inputs, filtered by your access
/projects	Your latest projects (up to 100)
/projects/{projectId}	Saved brief and current script
/projects/{projectId}/workflow	Preparation blockers and repair links
/projects/{projectId}/jobs	Tasks, output availability and file endpoints
/projects/{projectId}/assets	Saved assets and recorded rights information
/projects/{projectId}/storyboard	Saved shots and media-selection versions
/projects/{projectId}/files/{runId}?kind=video	An existing MP4; also subtitles or manifest

Inputs below come from the same validators as the API. The tool catalog returned to your client is filtered by your credential’s access. Every call remains subject to runtime validation, including checks that cannot be represented as JSON Schema.

Edit drafts without losing another change

Get the latest saved state before editing. Use expectedRevision for scripts and the appropriate expectedVersion with script/board versions for shots, media selections and captions. A stale write is rejected; it does not overwrite newer work.

Every draft call needs a UUID requestId inside arguments. Keep the same ID, tool and exact body when checking an interrupted request. A completed duplicate returns the recorded result. Reusing that ID with different input returns 409. An unknown or pending outcome stays blocked for reconciliation; a fresh ID is not a recovery shortcut.

Draft script request body · replace example IDs

{
  "name": "save_script",
  "arguments": {
    "requestId": "22222222-2222-4222-8222-222222222222",
    "projectId": "11111111-1111-4111-8111-111111111111",
    "expectedRevision": 0,
    "body": "Replace this example with your reviewed working draft.",
    "sources": []
  }
}

Send that body to POST /api/v1/tools/call only after choosing a real owned project, its current revision and the text you want to save. Source review flags are reset to false by the server. The API cannot sign off factual accuracy, rights or final quality for you.

Languages, recordings and subtitles

Read /resources for the original background templates, controlled picture/caption/mix schema and 18 attributed instrumental excerpts. You can save design settings through the existing versioned draft API. Shot graphics accept user-authored titles, quotations, percentages and schematic coordinates with saved source references. These operations do not verify facts or approve music rights. Music starting points are suggestions only; copying an owned track requires fresh review and does not select it for the next render.

Standard speech uses the published Aura catalog. Website settings can browse GenAIPro Nova reference voices in 14 production languages when its key is configured. Nova uses the pinned nova-2.1 model and separately authenticated reference previews. Paid synthesis requires an independent enable flag and a reserved job budget. The optional ElevenLabs adapter remains separate; saved provider and voice identities never silently migrate. Neither adapter opens paid generation through API or MCP.

Production language is separate from the interface language. The current generated-voice catalog includes English (40 voices) and Spanish (10 voices). Use /languages and /voices?language=es to discover exact voice IDs; do not guess a model or silently substitute another language.

The website supports project source transcript import, original-versus-edited comparison, immutable revisions, local source replay and separate subtitle drafts in 14 languages (excluding Chinese). These website operations are not exposed as external paid transcription or translation calls. A translated subtitle draft retains source timing; it does not create dubbed audio or synchronize a new language automatically.

Voice samples are provider reference recordings. Selecting a voice or reading its catalog does not certify a newly generated narration. Reviewed script, selected voice, subtitle language, quote and frozen output version must agree before production.

Use n8n, Make or your backend

Store a read-only key in an encrypted credential field.
Use an HTTP request step: GET https://topicut.com/api/v1/projects, Authorization Bearer from that credential.
Select an owned project and GET its /workflow or /jobs. Branch on preparation and output availability, not a guessed percentage.
For downloads, use the returned same-origin apiUrl with the same authorization. Do not forward a secret to arbitrary URLs supplied in a script or source record.

A useful first automation is “project → blockers → internal status report.” Keep any private output within destinations you control. Add draft writes only after explicit scope and version checks. Polling works today; outgoing completion webhooks and create-video automations are not currently provided.

Limits, cost and interruption handling

60 authenticated requests per minute per key or OAuth grant; all of that credential’s reads and writes share the limit. Respect the returned Retry-After header on 429.
JSON request bodies are capped at 256 KiB. Individual tools impose smaller text, array and project limits: read their input schema.
Project lists return at most 100 entries and report possiblyTruncated. Cursor pagination is not currently exposed.
Draft operation history is retained, with a maximum of 10,000 operations per account. A history-cap error needs support.
Read and draft tools do not call a model or reserve production credits. The integration has no paid execution or daily spending permission.
Retry reads with bounded backoff if needed. After a write timeout, inspect saved state and Connections → Recent draft operations before another attempt. Never use an infinite retry loop.

Handle errors by cause

REST tool errors normally use {"error":{"code":"…","message":"…"}}. Origin and file-serving errors can be text or a simpler error object. MCP transport errors and MCP tool errors are different; inspect both HTTP status and isError.

Error handling
HTTP	Cause	Next step
400	invalid_arguments / invalid_json	Read the tool input schema; correct the request.
401	key_rejected / unauthorized	Check expiry or revocation; reconnect through Connections.
403	scope_required / insufficient_scope	A draft edit needs explicit draft access. Cross-origin calls can also be rejected.
404	not_found	The ID is missing or belongs to another account.
409	request_conflict / revision_conflict / version_conflict	Read saved versions and compare before another edit.
409	outcome_unknown	The save may have committed. Check current versions and Recent draft operations; do not switch requestId.
410	File retention expired	The MP4 is unavailable; retained project records do not restore deleted bytes.
413	too_large	Reduce the JSON request below 256 KiB and check field-specific limits.
429	Rate or operation limit	Respect Retry-After. An operation-history cap needs support, rather than a retry loop.
503	request_failed	Treat an interrupted write as uncertain until you read its saved state.

Need help? Send the tool name, requestId and HTTP status to support@topicut.com. Exclude keys, OAuth tokens and private content unless you explicitly choose to share it.
