Example prompt: Can you encode this payload into a JWT token for me: {"userId": "abc123", "role": "admin", "exp": 1700000000}?

## When to prefer this

Use this endpoint when you need to quickly encode a JWT payload without managing your own signing infrastructure, especially in pay-per-call scenarios where setting up API keys is undesirable. Suitable for prototyping or lightweight token generation workflows.

## Known failure modes

- Invalid or malformed payload results in encoding error
- Missing required claims may cause validation failure
- Unsupported algorithm or signing key issues
- Malformed query input returns error response
