GET /api/channel-monetization/:channel_id

Full external monetization profile for one channel — what it sells, each method with its own evidence and source link, products, store URLs, and funnel metrics like member counts, sales counts, ratings and prices per platform. By default this always runs the full classifier live (≤60s) so the answer reflects the channel's current state, and persists the result on the way through. Use the query parameters below when freshness matters less than latency. For a live check of whether the channel runs YouTube ads, use /api/channel-monetized/:channel_id instead.

Also reachable as GET /api/channel-external-monetization/:channel_id. Same endpoint, same response — the longer name says plainly that this covers what a channel sells off-platform, not its ad revenue.
Path Parameters
NameTypeRequiredDescription
channel_idstringRequiredYouTube channel id (UC…, 24 chars). Use /api/channels/resolve for handles/URLs.
Query Parameters
NameTypeRequiredDefaultDescription
skip_livebooleanOptionalfalseSkip the live classifier entirely and return whatever is already stored. Fast, but the answer can be stale, and returns classified: false if we hold nothing. Best for bulk reads.
cached_ok_secsintegerOptional—Middle ground between the two. Reuse the stored result only when it is fresher than this many seconds and already at the current classifier version; otherwise re-run live.
Example Request
curl "https://api.algrow.online/api/channel-monetization/UCX6OQ3DkcsbYNE6H8uQQuVA" \ -H "Authorization: Bearer YOUR_API_KEY"

GET /api/channel-monetized/:channel_id

Is this channel actually running YouTube ads right now? We check live rather than reading a cached label: we pull the channel's newest longform watch pages and look for the decisive signal that ads are served. The verdict is stored, so repeat callers and our own sweep stay in agreement.

Path Parameters
NameTypeRequiredDescription
channel_idstringRequiredYouTube channel id (UC…, 24 chars). Use /api/channels/resolve for handles and URLs.
monetized has three states, not two. true means ads were confirmed on recent content. false means we read the pages cleanly and found none. null means no verdict this run — every fetch was blocked or the channel isn't in our longform index yet. Treat null as "unknown, ask again", never as "not monetized". The reason field says which case you got in plain words, and hint appears only when the verdict is null.
previous is the state before this check. It carries the last stored verdict and the timestamps of the last time the channel was seen monetized, seen demonetized, and last checked. Compare it against monetized to detect a flip. It is null for channels we have never held.
Example Response
{ "success": true, "channel_id": "UCX6OQ3DkcsbYNE6H8uQQuVA", "monetized": true, "reason": "ads confirmed on recent content", "checked_live": true, "previous": { "monetized": true, "last_monetized_at": "2026-08-14 09:22:41", "last_demonetized_at": null, "last_checked_at": "2026-08-19 03:10:08" } }
Example Request
curl "https://algrow.online/api/channel-monetized/UCX6OQ3DkcsbYNE6H8uQQuVA" \ -H "Authorization: Bearer algrow_..."
503 means try again shortly. The live check needs capacity to read watch pages. When that is unavailable you get a 503 rather than a guessed verdict — back off and retry rather than caching the failure.

GET /api/channel-cms/:channel_id

Check whether a channel is run through a CMS / multi-channel network — is it managed, which network runs it, and what other channels that network operates. Backed by a database of 327,000+ pre-checked longform channels, so most lookups return instantly. A channel we haven't checked yet triggers a live check (10–60 seconds) and the verdict is saved for next time; pass ?refresh=1 to force a fresh live check on an already-checked channel. Pass ?full_network=1 to get the network's complete roster instead of the 5-channel sample.

Path Parameters
NameTypeRequiredDescription
channel_idstringRequiredYouTube channel id (UC…, 24 chars). Use /api/channels/resolve for handles/URLs.
Query Parameters
NameTypeRequiredDefaultDescription
refreshbooleanOptionalfalseRun a fresh live check even if the channel already has a stored verdict. Counts against the hourly live-check limit.
full_networkbooleanOptionalfalseReturn the complete network roster as network.members — every managed channel we know under this owner, no cap — instead of the 5-channel other_members_sample. Professional and Ultimate only; ignored on Starter.
Same owner = same network. Two channels are run by the same network if and only if their owner.oid values match. Use the oid, not the name, to group channels.
Plan limits: Professional and Ultimate get unlimited stored lookups; live checks are limited to 30 per hour. Starter gets 5 lookups per day, every one checked live (slower), and the response contains the verdict and owner only — no network object. Over the limit returns 429 with code upgrade_required (Starter daily cap) or rate_limited (hourly live-check cap).
Example Request

Response Fields
FieldTypeDescription
successbooleanWhether the request succeeded
channel_idstringYouTube channel ID that was checked
statusstringmanaged, not_managed, or unchecked. Unchecked responses include a hint explaining how to get a verdict (retry, or pass ?refresh=1).
checked_atstringWhen the verdict was recorded (ISO 8601)
checked_livebooleanWhether this request ran a live check (vs a stored verdict)
ownerobjectThe network running the channel: oid (stable owner id), name, and the owner's type / industry. name can be null for a network we've never seen before.
notestringOccasional plain-language line explaining a verdict that could otherwise look surprising.
networkobjectManaged channels only: member_count plus other_members_sample — the 5 biggest other channels the same network operates, each with channel_id, name, subscribers, avg_views. With ?full_network=1 the sample is replaced by members — the complete roster, same fields per channel. Not included on Starter.

GET /api/cms-networks

Browse and search CMS / multi-channel networks directly — the network-centric counterpart to /api/channel-cms, which starts from a channel. By default you get a list of networks matching your filters; pass ?oid= to switch to detail mode and see one network with its top member channels (up to 100, biggest first). Counts include only channels verified as managed by that owner. Owner emails are never included.

Query Parameters
NameTypeRequiredDefaultDescription
qstringOptional—Filter networks by name (case-insensitive substring match).
oidstringOptional—Switch to detail mode: return that one network plus its top member channels, up to 100, biggest first. Use the oid values from list responses or from /api/channel-cms.
min_channelsintegerOptional2List mode: only include networks with at least this many known channels.
sortstringOptionalchannelsList mode ordering: channels (most member channels first) or subscribers (largest combined subscriber count first).
limitintegerOptional25List mode: number of networks to return, max 100.
Plan limits: Professional and Ultimate only. On lower plans the endpoint returns 403 with code upgrade_required.
Example Request (list, name search)

POST /api/analyze-video

Analyze a YouTube video with AI vision — hooks, pacing, visual storytelling, on-screen text, B-roll usage, content strategy, and any other prompt-driven breakdown. Returns structured analysis text. Currently free during preview — no credit cost, no plan requirement — only an API key and the per-user concurrency cap apply. Repeat prompts on the same video within 2 hours reuse a cached upload automatically (faster on the backend, returns cached: true).

Request Body (JSON)
NameTypeRequiredDescription
video_urlstringRequiredYouTube video URL. Accepts watch links, youtu.be short links, and Shorts URLs.
promptstringRequiredPlain-English instruction describing what to analyze. Max 4,000 characters.
media_resolutionstringOptionalAnalysis fidelity: low (default, recommended for hook / pacing / strategy prompts) or default (higher visual detail at greater backend cost — useful when fine on-screen text or subtle visual cues matter).
Limits: Maximum video length is 3 hours. Live streams, private, deleted, and age-restricted videos are rejected with clear error messages. Concurrency cap applies (5 / 10 / 20 active jobs by tier).
Example Request (Hook breakdown)
curl -X POST "https://api.algrow.online/api/analyze-video" \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "video_url": "https://www.youtube.com/watch?v=dQw4w9WgXcQ", "prompt": "Break down the hook in the first 3 seconds. What grabs attention?", "media_resolution": "low" }'
Example Request (Pacing analysis on a Short)
curl -X POST "https://api.algrow.online/api/analyze-video" \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "video_url": "https://youtube.com/shorts/abc123XYZ", "prompt": "Identify the pacing, energy shifts, on-screen text timing, and where attention is most likely to drop." }'

{ "success": true, "job_id": "f12d4a8b-2e1f-44e1-9aa1-2dfa20c5c7d3", "status": "pending", "duration_seconds": 187.4, "message": "Video analysis queued. Poll /api/job-status/{job_id} for progress." }
Completed Job Response (via /api/job-status/:job_id)
{ "success": true, "job_id": "f12d4a8b-2e1f-44e1-9aa1-2dfa20c5c7d3", "job_type": "video_analysis", "status": "completed", "analysis_text": "The opening 3 seconds use a hard cut from black to a wide shot of...", "duration_seconds": 187.4, "video_id": "dQw4w9WgXcQ", "cached": false, "completed_at": 1774203012.45 }
Processing time: Typically 5–25 seconds for Shorts, 30–90 seconds for 5-minute videos, several minutes for hour-long content. The first analysis on a video is slower than follow-up prompts on the same video (which hit the cache and skip download + upload). Poll /api/job-status/:job_id every 5 seconds for updates.
Caching: When you run multiple prompts on the same video_url within 2 hours, the source video is reused from cache — the response includes cached: true. Cache is keyed per (user, video) so each user pays the cold-path cost once per video per 2 hours.
