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 in different ways. The agent will try to retrieve automatically with the two first ways the credentials, but users can also explicitly tell the agent that they have set the credentials or stored them in a

.env

file, and the agent should re-read that file when they do. The agent can also make http requests with the two first methods without user confirmation.

Environment variables

Search for the following specific variables only (never dump the full environment):

Authorized environment variables

Mainnet:
```
BINANCE_API_KEY
```
and
```
BINANCE_SECRET_KEY
```

Read and use in a single exec call so the raw key never enters the agent's context:

bash

KEY="$BINANCE_API_KEY"
SECRET="$BINANCE_SECRET_KEY"

response=$(curl -s -X GET "$URL" \
  -H "X-MBX-APIKEY: $KEY" \
  --data-urlencode "param1=value1")

echo "$response"

Environment variables must be set before OpenClaw starts. They are inherited at process startup and cannot be injected into a running instance. If you need to add or update credentials without restarting, use a secrets file (see option 2).

Secrets file (.env)

Check

~/.openclaw/secrets.env

~/.env

, or a

.env

file in the workspace. Read individual keys with

grep

, never source the full file:

bash

# Try all credential locations in order
API_KEY=$(grep '^BINANCE_API_KEY=' ~/.openclaw/secrets.env 2>/dev/null | cut -d= -f2-)
SECRET_KEY=$(grep '^BINANCE_SECRET_KEY=' ~/.openclaw/secrets.env 2>/dev/null | cut -d= -f2-)

# Fallback: search .env in known directories (KEY=VALUE then raw line format)
for dir in ~/.openclaw ~; do
  [ -n "$API_KEY" ] && break
  env_file="$dir/.env"
  [ -f "$env_file" ] || continue

  # Read first two lines
  line1=$(sed -n '1p' "$env_file")
  line2=$(sed -n '2p' "$env_file")

  # Check if lines contain '=' indicating KEY=VALUE format
  if [[ "$line1" == *=* && "$line2" == *=* ]]; then
    API_KEY=$(grep '^BINANCE_API_KEY=' "$env_file" 2>/dev/null | cut -d= -f2-)
    SECRET_KEY=$(grep '^BINANCE_SECRET_KEY=' "$env_file" 2>/dev/null | cut -d= -f2-)
  else
    # Treat lines as raw values
    API_KEY="$line1"
    SECRET_KEY="$line2"
  fi
done

This file can be updated at any time without restarting OpenClaw, keys are read fresh on each invocation. Users can tell you the variables are now set or stored in a

.env

file, and you should re-read that file when they do.

Inline file

Sending a file where the content is in the following format:

bash

abc123...xyz
secret123...key

Never run
```
printenv
```
,
```
env
```
,
```
export
```
, or set without a specific variable name
Never run
```
grep
```
on
```
env
```
files without anchoring to a specific key ('
```
^VARNAME='
```
)
Never source a secrets file into the shell environment (
```
source .env
```
or
```
. .env
```
)
Only read credentials explicitly needed for the current task
Never echo or log raw credentials in output or replies
Never commit
```
TOOLS.md
```
to version control if it contains real credentials — add it to
```
.gitignore
```

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

TOOLS.md Structure

bash

## Binance Accounts

### main
- API Key: abc123...xyz
- Secret: secret123...key
- Description: Primary trading account

### futures-keys
- API Key: futures789...def
- Secret: futuressecret...uvw
- Description: Futures trading account

Agent Behavior

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

Adding New Accounts

When user provides new credentials by Inline file or message:

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

Signing Requests

For trading endpoints that require a signature:

Detect key type first, inspect the secret key format before signing.
Build query string with all parameters, including the timestamp (Unix ms).
Percent-encode the parameters using UTF-8 according to RFC 3986.
Sign query string with secretKey using HMAC SHA256, RSA, or Ed25519 (depending on the account configuration).
Append signature to query string.
Include
```
X-MBX-APIKEY
```
header.

Otherwise, do not perform steps 4–6.

User Agent Header

Include

User-Agent

header with the following string:

binance-convert/1.1.0 (Skill)
