Free Models and Telegram Verification

Verify with the KiosAPI Telegram bot to unlock the free model group at zero cost.

Free Models and Telegram Verification

KiosAPI offers a Free group with a set of models that cost nothing to use (group multiplier is 0). To keep this sustainable, access to the Free group is gated behind a one-time Telegram verification — you prove you are a real person by joining the official KiosAPI Telegram chat through the verification bot.

Prerequisites

• A KiosAPI account
• A Telegram account
• An API key created in the Free group (see Choosing a Token Group)

Step 1 — Create a Free-group API key

1. Go to Console → Tokens in the dashboard.
2. Click Add Token.
3. Select the group Free.
4. Save and copy the key.

Step 2 — Start Telegram verification

1. In the dashboard, open the verification panel (shown when you try to use a Free-group key, or via the account settings area).
2. Click Verify via Telegram. The dashboard shows a button/link to open the official verification bot: @kiosapi_verif_bot.
3. The bot opens in Telegram. Press Start (or send /start).
4. The bot sends you a verification link. Tap it — it joins you to the required KiosAPI Telegram chat and confirms back to the site.

The verification link is personal, expires in 10 minutes, and only works from the Telegram account that started the chat with the bot. If it expires, just start again from the dashboard.

Step 3 — Complete verification

1. After the bot confirms, return to the KiosAPI dashboard.
2. Click Complete verification (the page refreshes your status automatically in most cases).
3. Your status shows verified, with the Telegram account you used.

Step 4 — Use free models

Your Free-group key can now call the free models. Try one:

curl https://kiosapi.com/v1/chat/completions \
  -H "Authorization: Bearer sk-xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "glm-5.3-flash-free",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

The current free model list (Agnes, Atria, GLM flash-free, gpt-oss-20b, and others) is on the Models & Pricing page — filter by the Free group.

Rules and details

• Verification is per Telegram account and per KiosAPI account, and is re-checked periodically. If you leave the Telegram chat, free access stops working until you rejoin.
• Free models are shared capacity: expect rate limits and no SLA. For production workloads use a paid group.
• Zero-cost means the group multiplier is 0 — abnormal or abusive usage can still be restricted by the platform.

Troubleshooting

Symptom	Fix
”Verification required” error on a Free key	Complete the steps above — the key group is Free but your account is not verified
Bot link expired	Request a new link from the dashboard (links expire after 10 minutes)
Verified but still failing	Make sure you are still a member of the Telegram chat; re-check status in the dashboard
Different Telegram account than expected	Verification is bound to the Telegram account that pressed Start — redo it with the account you plan to keep
