Free post tools for AI agents

Plug SocialNexis into Claude, OpenClaw, Cursor, or any agent that can call an API. Detect AI-writing tells, check a LinkedIn or X draft against documented best practices, and generate structured post ideas. No API key, no signup.

Three tools, zero setup

1. AI-writing detector (instant, deterministic)

Twelve checks with line-level findings: em dashes, markdown syntax (LinkedIn and X render none), AI buzzwords, unattributed "studies show" claims, self-labeled takes, engagement bait, throat-clearing openers, hashtag stuffing, and more. Every finding comes with the exact quote, its character range, and a prescriptive fix.

curl -s -X POST https://api.socialnexis.com/api/v1/public-tools/tells \
  -H 'content-type: application/json' \
  -d '{"body": "Excited to share this game-changer — thoughts?"}'

2. Full post analysis

Everything in the detector, plus a six-axis quality rubric (substance, hook, concreteness, topic clarity, question quality, self-containedness) and a structure match: which of our 12 proven post templates your draft resembles, and the one beat it misses.

curl -s -X POST https://api.socialnexis.com/api/v1/public-tools/analyze \
  -H 'content-type: application/json' \
  -d '{"body": "<your draft>"}'

3. Post ideas

Three distinct, structured ideas from a topic or a pasted article, each with a hook, thesis, outline, and a named post structure. Ideas never invent citations: facts come only from the text you provide.

curl -s -X POST https://api.socialnexis.com/api/v1/public-tools/ideate \
  -H 'content-type: application/json' \
  -d '{"topic": "engineering hiring", "text": "<optional article text>"}'

Anything else

The endpoints are plain HTTPS + JSON. Paste the curl examples above into any agent's instructions, and see the full API reference for response schemas, error codes, and limits. Free daily limits: 40 detector scans, 10 full analyses, and 2 idea batches (6 ideas) per user.

These tools are the generic layer

The full product drafts in your voice, ideates from your sources without ever repeating itself, and runs your LinkedIn and X engagement on autopilot with a real browser. The free tools tell you what's wrong; SocialNexis does it right the first time.
