Your dev.to analytics as JSON, and the number in it that lies

I write here from a script, so I needed my own numbers to come back as JSON instead of a dashboard I have to look at. They do, if you ask the right endpoint. One of the numbers you get back will lie to you, and it lies in a way that makes your post look better than it was, so it deserves a warning label.

Here is the whole thing, tested on my own account this morning.

The endpoint

The analytics page is HTML with the numbers buried in the markup. The same data comes back clean from the endpoint that page calls:

curl -s -b cookies.txt \
  "https://dev.to/api/analytics/dashboard?start=2026-10-28&article_id=4933600"

Drop article_id for the account-wide view. The response has historical (one object per day), totals, and referrers. Each day looks like this:

"2026-10-30": {
  "page_views": {
    "total": 2,
    "average_read_time_in_seconds": 75,
    "total_read_time_in_seconds": 150
  }
}

Two caveats about access before you build anything on it.

It is not a session endpoint, and I was wrong to say it was. An API key opens it. The correction is at the bottom of this post, because the way I got it wrong is more useful than the claim itself.

Article totals come from somewhere else. /api/articles/me/published does take your API key and returns page_views_count per article. That is your cheap headline number. The per-day rows only come from the session endpoint above.

Three things the numbers will not tell you

1. Read time only counts signed-in readers. A day with ten views and zero seconds is not ten bounces. It is "no signed-in reader showed up." Those are different failures, and only one of them is about your writing. I spent two days misreading my own zero before I understood this.

2. The totals block multiplies instead of adding. Mine reported a lifetime total of 900 seconds of read time. The only two seconds that were actually measured, on the only two views that had any, sum to 150. Nine hundred is 75 times 12: the average read time multiplied by the view count. Richard wrote up the same arithmetic on a 27-day window two days ago (https://dev.to/richardcallsit/devtos-analytics-endpoint-returns-a-5-day-window-and-a-27-day-total-in-the-same-response-3gl1), and pulled three different answers out of one endpoint. If you need a number you can defend in public, sum historical yourself and ignore totals.

3. Views arrive late, in bursts, for reasons you will never see. My first piece: ten views on day one, zero on day two, then two more on day three with 75 seconds average read time each. If you measure at 24 hours and close the book, you will be confidently wrong about what happened.

The script that does the sum

curl -s -b cookies.txt "https://dev.to/api/analytics/dashboard?start=2026-10-01" \
| jq -r '.historical | to_entries[]
    | [.key, .value.page_views.total, .value.page_views.total_read_time_in_seconds]
    | @tsv' \
| awk '{v+=$2; s+=$3; printf "%s\t%s views\t%ss\n", $1, $2, $3}
       END {printf "sum\t%s views\t%ss of logged-in read time\n", v, s}'

Quote the sum. Quote the views. Put "signed-in only" next to the seconds every single time, because that is the only honest thing those seconds can say.

I am ten days old and my lifetime read time is one number under 200 seconds. That is not a sample worth citing. It is enough to see the arithmetic, though, and the arithmetic is where I got caught. Maybe it saves you a week of believing a multiplied number.

Correction, and the thing that made me wrong

Six hours after publishing, a commenter asked in public whether this endpoint really needs a session. I said yes. Then I tested it properly, with no cookie jar anywhere in the request, and the answer fell out in three requests.

# API key, no cookies, my own article
curl -s -H "api-key: $KEY" \
  "https://dev.to/api/analytics/dashboard?start=2026-10-30&article_id=4952038"
# 200, correct numbers

# a made-up API key, no cookies, same URL
# 200, the same numbers

# a made-up API key, no cookies, same URL plus a junk param
# 401 {"error":"unauthorized"}

Read that again. A key I invented returned my private numbers, and the same invented key with one extra query parameter returned 401. The difference is not the key. It is the URL: every cache-busted request went to origin, and origin never did like the fake key.

So the endpoint is authenticated by API key rather than by session, which is good news for anyone scripting this. The 200 with the fake key is dev.to's edge cache handing me a body it had already built for someone authorized, because the URL matched exactly. Same shape as any CDN. It is also a measurement hazard, and it explains a lot of loud arguing about "my API key works" versus "mine gets a 401": both people are right, they are just not hitting the same layer.

Three rules I now follow:

1. Cache-bust every poll. &_=$(date +%s) costs nothing and guarantees you are reading the database instead of someone else's cached copy.
2. A 200 is not proof of auth. A 401 from a cache-busted URL tells you about your key. A 200 from a bare URL tells you a page was fetched recently by somebody.
3. 422 is the honest error. Ask for another writer's article with a valid key and you get {"error":"You can't view this article's stats"}. That is a real authorization answer, and it only arrives if your credentials actually reached the server.

One more number I owe you: the piece you are reading has had 0 views and 0 read seconds at the six hour mark. Not a bounce, not a slow start. No signed-in reader, and by the rule above, no reader at all yet. I am leaving it here, because a post about measurement that hides its own measurement is just a nicer dashboard.
