News bot's OpenPageRank gate lets 5 of 270 daily stories reach X at $0.20 each

The spending policy for X is one line of bot.py: `X_MIN_OPR = int(os.environ.get("X_MIN_OPR", "6"))`, commented "X costs money per post; only the best go there" ^[5]. A story reaches X only when its source has an OpenPageRank of 6 or more. Everything else goes to Bluesky alone ^[4]. "That threshold is the difference between a $204 and a $30 monthly bill, and it comes from the feed's own numbers, not from taste," the authors wrote ^[6].

The score belongs to the publisher, not the article. Under this rule a strong story from a small trade site stays on Bluesky, while a thin rewrite from a high-ranked domain goes to X ^[4]. For a single-industry feed I think that is a fair proxy.

The number of stories that qualify for X under the threshold changes daily. Each run posts up to three new stories to Bluesky and forwards the qualifying ones to X ^[8], with the limit set by MAX_PER_RUN, default 3 ^[9]. One run every 30 minutes is 48 runs a day ^[1]. The ceiling is 144 X posts a day, or $28.80, about $864 over a 30-day month ^[2]. Arrivals are uneven: the busiest 30-minute slot in the raw pull had 21 articles, the median slot 4 ^[10]. The measured day produced 5 X posts and $1.00 of charges ^[3]. The $30 monthly figure ^[7] comes from one day, 16 September 2026, of English-language Renewable Energy news ^[3]. In the five steps the post lists, the per-run cap is the only limit on X spend ^[8].

The URL is where the money goes. According to the X pricing page the post quotes, a link raises the per-post price from $0.015 to $0.200, about 13.3 times ^[1][4]. Sending all 34 stories without links would cost $15.30 a month, against $204 with them ^[5][7].

On a paid network, each duplicate that gets past dedupe is billed. The authors measured the API's `is_duplicate` flag and URL matching, and together they removed 0 of 270 articles ^[11]. Syndicated copies arrive with different URLs on different domains ^[11]. Lowercasing titles and stripping punctuation removed 18, including one story, "Egypt's wind power push", published six times ^[11]. Posted to X, those six copies would have been billed six times, $1.20 for one headline ^[6].

The image flags got the same scrutiny. `has_social_share_image=1` is meant to keep only images of at least 1200x630, and it cut the 270 articles to 35 ^[12]. Of 29 share images the bot fetched, 5 were over Bluesky's 1,000,000-byte blob limit and 6 were below 1200x630 despite the flag ^[14]. The script prepares each thumbnail itself with Pillow so every Bluesky card carries an image under 1,000,000 bytes ^[16]. Checking a vendor's flags against the actual files is the part of this build I would copy first. The flag choice also sets volume, since `has_image=1` would have passed 147 articles ^[12]. "A bot posting 147 stories a day is spam; 35 is a feed," the authors wrote ^[13].

For the $30 to hold in another team's pipeline, its feed needs a similar shape: 270 raw articles a day, with 5 of them, under 2%, from sources at OpenPageRank 6 or above ^[3][7]. The evidence is a single day of a single industry feed, with flags and articles from APITube's news API ^[15]. The counts also do not line up. The funnel ends at 35 share-image stories, the all-to-X cost line uses 34, and only 29 images were fetched ^[3][7][14]. The post does not reconcile them.
