Bankr Error Handling

Resolve Bankr API errors and authentication issues.

Authentication Errors (401)

Symptoms

HTTP 401 status code
"Invalid API key" or "Unauthorized" message

Resolution

Present these setup instructions to the user:

Step 1: Create an API Key

Visit https://bankr.bot/api to create a new API key

Step 2: Set Environment Variable

bash

# Add to shell profile (~/.zshrc or ~/.bashrc)
export BANKR_API_KEY=bk_your_api_key_here

Step 3: Restart Claude Code

Close and reopen the terminal/Claude Code session

Important: Do NOT retry when authentication fails. User must fix API key first.

Common Job Failures

Error	Cause	Resolution
Insufficient balance	Not enough tokens	Check balance, reduce amount
Token not found	Invalid symbol/address	Verify token exists on chain
Slippage exceeded	Price moved too much	Retry or try smaller amount
Transaction reverted	On-chain failure	Check transaction details
Rate limit exceeded	Too many requests	Wait and retry

HTTP Status Codes

Code	Meaning	Action
400	Bad request	Check prompt format
401	Unauthorized	Fix API key (see above)
402	Payment required	Ensure wallet has BNKR on Base
429	Rate limited	Wait and retry

Troubleshooting Checklist
