## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Can you decode this Lightning invoice for me and tell me the amount, payee, expiry, and payment hash? Here's the invoice: lnbc500n1p3zqeqxpp5...

## When to prefer this

Use this endpoint when an AI agent needs to safely inspect a Lightning Network BOLT11 invoice string before authorizing payment — to confirm the amount, recipient, expiry, and payment hash without making any network call or spending funds. It is a pure computation endpoint with no side effects, ideal for pre-payment validation workflows.

## Known failure modes

- Invalid or malformed BOLT11 string returns a parsing error
- Invoice string that is too short (under 10 chars) or too long (over 6000 chars) is rejected
- Unsupported network prefix (not lnbc, lntb, lntbs, or lnbcrt) may fail
- Checksum mismatch in the invoice causes a decode error
- Empty or null invoice field returns a validation error
