lightning-decodepay -- Command for decoding a bolt11 string (low-level)

SYNOPSIS

decodepay bolt11 [description]

DESCRIPTION

The decodepay RPC command checks and parses a bolt11 string as specified by the BOLT 11 specification.

RETURN VALUE

On success, an object is returned, containing:

• currency (string): the BIP173 name for the currency
• created_at (u64): the UNIX-style timestamp of the invoice
• expiry (u64): the number of seconds this is valid after timestamp
• payee (pubkey): the public key of the recipient
• payment_hash (hex): the hash of the payment_preimage (always 64 characters)
• signature (signature): signature of the payee on this invoice
• min_final_cltv_expiry (u32): the minimum CLTV delay for the final node
• amount_msat (msat, optional): Amount the invoice asked for
• description (string, optional): the description of the purpose of the purchase
• description_hash (hex, optional): the hash of the description, in place of description (always 64 characters)
• payment_secret (hex, optional): the secret to hand to the payee node (always 64 characters)
• features (hex, optional): the features bitmap for this invoice
• fallbacks (array of objects, optional): onchain addresses:
  • type (string): the address type (if known) (one of "P2PKH", "P2SH", "P2WPKH", "P2WSH")
  • hex (hex): Raw encoded address
  • addr (string, optional): the address in appropriate format for type
• routes (array of arrays, optional): Route hints to the payee:
  • hops in the route:
    • pubkey (pubkey): the public key of the node
    • short_channel_id (short_channel_id): a channel to the next peer
    • fee_base_msat (u32): the base fee for payments
    • fee_proportional_millionths (u32): the parts-per-million fee for payments
    • cltv_expiry_delta (u32): the CLTV delta across this hop
• extra (array of objects, optional): Any extra fields we didn't know how to parse:
  • tag (string): The bech32 letter which identifies this field (always 1 characters)
  • data (string): The bech32 data for this field

Technically, the description field is optional if a description_hash field is given, but in this case decodepay will only succeed if the optional description field is passed and matches the description_hash. In practice, these are currently unused.
