Score any post draft in seconds. Two free endpoints, no auth:
Instant AI-tells scan (deterministic)
curl -s -X POST https://api.socialnexis.com/api/v1/public-tools/tells \
-H 'content-type: application/json' \
-d '{"body": "<the post draft>"}'
Twelve checks, each finding with a verbatim quote, char range, and a
prescriptive reason:
- AI punctuation tells — em dashes, ellipsis, curly quotes
- Markdown artifacts — LinkedIn/X render NO markdown;
**bold**and# headingsshow as literal characters - AI buzzwords — game-changer, delve, seamless, move the needle...
- Unattributed authority — "studies show", "experts believe"
- Self-labeled takes — "hot take:", "unpopular opinion:"
- Engagement bait — "comment YES", "tag a friend" (LinkedIn downranks these)
- Weak openers — "I'm excited to share...", plus fold length, hashtag stuffing, wall-of-text scannability
Full analysis (adds a judged quality rubric + structure match)
curl -s -X POST https://api.socialnexis.com/api/v1/public-tools/analyze \
-H 'content-type: application/json' \
-d '{"body": "<the post draft>"}'
Everything above PLUS six judged axes (substance, hook, concreteness, topic
clarity, question quality, self-containedness) and templateMatch: which of
12 proven post structures the draft resembles and the beat it misses. Takes a
few seconds; input limit 15,000 chars.
How to apply results
Locate each finding's quote at its range in the draft, rewrite per its
reason, then re-run until clean. Fix enforce-tier flags first.
