Quick Start (5 min)

Four steps to get going.

1. Sign up, then claim your trial credit

Open the sign-up page and register with your email (or a third-party login).

• Email verification is required: enter your email → get the code → finish sign-up.
• After signing up, contact our support to claim free trial credit (WeChat / Telegram / email — see Support). The credit works for pay-as-you-go.

2. Top up or subscribe (optional)

When your credit runs out:

• Top up: on the purchase page choose an amount (denominated in USD; paid in CNY at the live exchange rate).
• Subscribe: VIP / SVIP plans for heavy usage — see Subscription Plans.

3. Create an API key

Go to API Keys → Create → copy the key (sk-...).

🔐 Treat your API key like a password. Never share it or commit it to public repos.

4. Start calling

HJToken is compatible with OpenAI and Anthropic APIs. Point your tool/code at HJToken's base URL and use your key.

  -H "Authorization: Bearer $HJTOKEN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-5.4","messages":[{"role":"user","content":"Hello"}]}'
