How do I get views, coins and danmaku count for a Bilibili BV id?

A campaign report lands on your desk with 200 BV ids and claimed view numbers. Before you sign off, you want the real numbers for each one, including coins, which on Bilibili say more about how much viewers liked a video than likes do. One API call per BV id gets you all of it.

The endpoint

Bilibili video detail takes either id (a BV id such as BV1xx411c7mD) or url (the full bilibili.com/video/... link). Give one, not both. With view=full, this is where each number lives:

What you want	Field
Views	metrics.views
Likes	metrics.likes
Coins	ext.coins
Favorites	metrics.favorites
Shares	metrics.shares
Comments	metrics.comments
Danmaku count	ext.danmaku
aid (the old AV number)	ext.aid
cid (of the first part)	ext.cid
Duration, seconds	ext.duration_s
Section	ext.section

Title, description, cover, publish time and the uploader's name and mid come back too.

Cost

Batch	Calls	Cost
One video	1	$0.002
A 200-video campaign report	200	$0.40
1,000 videos	1,000	$2.00

A deleted or private video returns not_found, which is not charged.

Batch script

import csv, os, requests

URL = "https://api.okdata.online/v1/bilibili/videos/get"
H = {"Authorization": f"Bearer {os.environ['OKDATA_API_KEY']}"}

bvids = [line.strip() for line in open("bvids.txt") if line.strip()]
with open("stats.csv", "w", newline="", encoding="utf-8-sig") as f:
    w = csv.writer(f)
    w.writerow(["bvid", "views", "likes", "coins", "favorites", "danmaku", "fetched_at"])
    for bv in bvids:
        body = requests.get(URL, headers=H, params={"id": bv, "view": "full"}, timeout=60).json()
        if body["code"] != "ok":
            w.writerow([bv, body["code"]])
            continue
        v = body["data"]["item"]
        w.writerow([bv, v["metrics"]["views"], v["metrics"]["likes"], v["ext"]["coins"],
                    v["metrics"]["favorites"], v["ext"]["danmaku"], body["meta"]["fetched_at"]])

Things to keep in mind

• The numbers are a snapshot. Keep meta.fetched_at next to them, because a video's views can double in a day.
• Multi-part videos share one BV id; the counts cover the whole video, and ext.cid is the first part's.
• Completion rate, traffic sources and audience age are private to the uploader. No public API has them.
• If you only need the aid, you do not need a call at all. The BV-to-AV conversion is a published algorithm (bilibili-API-collect documents it), and a few lines of code run it locally for free.

Other ways

For five videos, open the pages and copy the numbers. If you run the campaign yourself, the creator center (创作中心) export from the uploader is richer than any public number. The open-source bilibili-api library reads the same public stats for free if you maintain it. To turn one-off lookups into ongoing tracking, see the competitor monitoring guide.
