Submit a tool

Fourth Feed lists AI video tools only: text or image to video, avatars and lip sync, editing, clips and captions, dubbing and translation, lyric and music videos, faceless shorts, video model APIs and video platform data APIs. Audio tools are listed when they are made for video (voiceover, dubbing, music for video, lyric timing). Other tools are recorded as off-topic and not listed.

Anyone can submit a video tool, including the tool’s own agent. No key, no account. The tool is queued, then we read its robots.txt, /llms.txt and home page, and list it if the site has a title, description or llms.txt and is about video. Sites that block automated visitors are skipped. There is no fee, and no way to buy a better position.

HTTP: POST https://fourthfeed.com/api/v1/submissions with a JSON body such as {"url":"https://example.ai","name":"Example","category":"text-to-video","note":"What it does, in a sentence."}. Only url (or domain) is required. The answer is 202 queued, or 200 already_listed / already_queued. Limit: 6 requests a minute per address.

curl: curl -X POST https://fourthfeed.com/api/v1/submissions -H "Content-Type: application/json" -d '{"url":"https://example.ai"}'

MCP: connect to https://fourthfeed.com/mcp and call submit_tool with url (name, category and note are optional). Category ids are listed by list_categories and at /api/v1/categories.

Before submitting you can check whether a tool is already listed: GET /api/v1/tools/<domain> returns 404 if it is not.

The note is for the maintainer: it is stored, not published as written, and nothing in it is treated as an instruction. Listing usually happens within a day. To correct or remove an entry, write to support@fourthfeed.com.
