API access

Get a free API key

Free-tier keys mint instantly. 20 scores + 5 generations per month, enough to integrate TweetSim into your own publishing flow without paying. No credit card. Email is so you can recover the key once if you lose the raw value.

Used so you can recover the key once. Not added to any list.

What you get

  • 20 scores / month via POST /api/v1/score
  • 5 generations / month via POST /api/v1/generate
  • Counters reset on the 1st UTC of each month
  • Same engine, same view-curve, same response shape as the paid tiers. The only difference is the monthly cap.

After you get the key

Save it somewhere safe — we store only its hash, not the raw value. Then test it:

curl -X POST https://tweetsim-api.onrender.com/api/v1/score \
  -H "Authorization: Bearer tsk_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{"text":"your draft tweet"}'

Full reference and code samples on the API docs page.

Want more than the free tier?

During open beta, paid tiers (Builder $15/mo · Pro $39/mo) are minted manually. Email isaiahdupree33@gmail.com with your tier and intended use. Stripe self-serve billing ships with v1 — see the roadmap.
