Hand Pulse a public post URL — YouTube, X, TikTok, Bluesky, Instagram, Threads — and get back its views, likes, comments, shares, author, and publish date as JSON. Profiles too: a profile URL returns followers. One GET. No signup, no API key. Free.
Free · no account · no key · 4 platforms live, more in beta
The same request shape for every platform. Here's a real response.
# one call, any public post — no key, no signup curl "https://pulse.walls.sh/metrics?url=https://www.tiktok.com/@khaby.lame/video/6967348974688816390" { "platform": "tiktok", "views": 39600000, "likes": 5500000, "comments": 39500, "publishedAt": "2021-05-28T14:32:30.000Z", "title": "Boss.. one shot - 3 points" }
/metricsOne post URL → views, likes, comments, author, thumbnail, publish date. Short links (vm.tiktok.com, t.co) resolve automatically.
/metrics/batchUp to 50 posts in one request — order preserved, one bad URL never fails the batch.
/historyThe growth curve: every fresh fetch records a snapshot, so repeat lookups build the post's series over time.
/profileA profile URL → followers, following, post count, verified. YouTube, TikTok, Instagram, X, Bluesky.
Live, against this API, right now. A post URL returns its metrics; a profile URL returns followers. No signup — it's free.
Read straight from each platform's own public pages. Live status, kept honest.
Discoverable via OpenAPI and llms.txt, callable with one GET, and payable over x402 if you want — no human in the loop, no dashboard.
Nothing to set up. Hit a URL, get JSON. There's no account to create and no API key to manage.
Every platform returns views · likes · comments · publishedAt. Integrate once, cover them all.
Pulse reads the same public engagement a logged-out visitor sees on each platform's own page, and tidies it into JSON.
A deleted or private post returns a clean 404 content_unavailable — never silent zeros you'd mistake for real data.
Every call is free right now. No signup, no key, no card. Pulse can also take payment per call in USDC over x402 (that's how agents pay their own way) — but that's off, and this isn't here to make money. It's a small, useful tool.
No. Pulse has no signup and no keys. Your agent calls /metrics?url=… directly and gets JSON back.
Yes. Every call is free right now. Pulse also speaks x402 so an agent can pay per call in USDC if billing is ever turned on — but the default is just: use it.
x402 is the open "HTTP 402 Payment Required" standard. It lets software pay for a request with a USDC micro-payment and retry — gasless, no human in the loop. Pulse supports it so agents can pay their own way.
YouTube, X/Twitter, TikTok, and Bluesky are live and verified. Instagram and Threads are in beta; LinkedIn is coming. See the live status above.
Yes — Pulse reads the same public engagement numbers a logged-out visitor sees on each platform's own pages, and normalizes them into one JSON shape.
Yes — CORS is enabled for all origins, so a dashboard or browser-based agent can fetch() Pulse directly. No key needed.
You get a clean 404 {"error":"content_unavailable"} — never fabricated zeros.
Open the docs, copy the curl, run it. That's the whole thing.
