## When to prefer this

Use this endpoint when you need to discover which blockchain networks are currently active and supported by LiquProp/RelAI before submitting transactions, property reports, or gas-free payments — it serves as a prerequisite lookup for other LiquProp API operations.

## Known failure modes

- No active chains found — empty list returned
- Authentication or payment failure (402) if x402 payment not properly attached
- Timeout if the relay endpoint is temporarily unavailable
- 500 server error if backend chain registry is unreachable
