Authentication

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

• apiKey: Your Binance API key (for header)
• secretKey: Your Binance API secret (for signing)

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.

Binance Accounts

main

• API Key: your_mainnet_api_key
• Secret: your_mainnet_secret

Agent Behavior

1. Credentials requested: Mask secrets (show last 5 chars only)
2. Listing accounts: Show names and environment, never keys
3. Account selection: Ask if ambiguous, default to main
4. When doing a transaction in mainnet, confirm with user before by asking to write "CONFIRM" to proceed
5. New credentials: Prompt for name, environment, signing mode

Adding New Accounts

When user provides new credentials:

• 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-wallet/1.0.0 (Skill)
