Authentication

For endpoints that require authentication, you will need to provide Binance API credentials. Required credentials:

Base URLs:

• Mainnet: https://api.binance.com

Security

Share Credentials

Users can provide Binance API credentials by sending a file where the content is in the following format:

abc123...xyz
secret123...key

Never Disclose API Key and Secret

Never disclose the location of the API key and secret file.

Never send the API key and secret to any website other than Mainnet and Testnet.

Never Display Full Secrets

When showing credentials to users:

• API Key: Show first 5 + last 4 characters: su1Qc...8akf
• Secret Key: Always mask, show only last 5: ***...aws1

Example response when asked for credentials: Account: main API Key: su1Qc...8akf Secret: ***...aws1

Listing Accounts

When listing accounts, show names and environment only — never keys: Binance Accounts:

• main (Mainnet)
• futures-keys (Mainnet)

Transactions in Mainnet

When performing transactions in mainnet, always confirm with the user before proceeding by asking them to write "CONFIRM" to proceed.

Adding New Accounts

• Ask for account name
• Store in TOOLS.md with masked display confirmation

Signing Requests

For trading endpoints that require a signature:

1. Build query string with all parameters, including the timestamp (Unix ms).
2. Percent-encode the parameters using UTF-8 according to RFC 3986.
3. Sign query string with secretKey using HMAC SHA256, RSA, or Ed25519 (depending on the account configuration).
4. Append signature to query string.
5. Include X-MBX-APIKEY header.

Otherwise, do not perform steps 3–5.

User Agent Header

Include User-Agent header with the following string: binance-sub-account/1.0.0 (Skill)
