How do I format phone numbers for sending SMS?

Phone numbers must include the country code without the 00 prefix. For example: China uses 86 (e.g., 8615800000000), Brazil uses 55 (e.g., 5511999999999), US uses 1 (e.g., 12025551234). The number should be 5-20 digits total. For Chinese domestic SMS, the message must start with a registered signature like [YourBrand].

What's the difference between send_sms and send_international_sms tools?

The `send_sms` tool uses the standard SMS gateway (smssh.253.com) optimized for Chinese domestic messages and requires pre-registered templates and signatures. The `send_international_sms` tool uses the international gateway (intapi.253.com) for global delivery outside China, which supports SenderId and doesn't require Chinese-style signatures. International SMS permissions must be separately enabled in your account.

How does the MD5 signature authentication work?

The Chuanglan API uses MD5 signature authentication for security. Your password is NEVER sent in the request body. Instead, it's combined with the request parameters and timestamp (nonce), then hashed with MD5 to generate a `sign` header. The server validates this signature to ensure request integrity. The framework handles all signature generation automatically — you only need to provide your account and password.
