Tools of Brük — verified XRP Ledger answers
	Description		Read-only	Idempotent	Open world
`free_send_check`Free, one per user per day. Before sending XRP or a token on the XRP Ledger: will the payment fail (missing destination tag, unfunded or deleted account, no trust line, wrong issuer) and what should you double-check? Returns the verdict, blockers, and cautions from a validated ledger. The paid send_check adds the full evidence and has no daily limit.	Free, one per user per day.

`issuer_check`Checks whether an XRP Ledger token issuer is who it claims to be: two-way domain verification (on-ledger Domain field against the domain's xrp-ledger.toml), tokens issued and outstanding, and control flags such as freeze, clawback, blackholed, and multisign. Useful before accepting or holding a token. The first call each day returns the real answer without payment. After that, about $0.01 via x402 (USDC on Base, or XRP / RLUSD on the XRP Ledger). A payment watch is paid from the first call. Bad input and ledger outages are never charged.

`send_check`Pre-send check for an XRP Ledger payment: whether the destination is activated, requires a destination tag, blocks or pre-approves senders, can hold the token (trust line, or MPT opt-in and issuer approval), is blackholed, and whether the source can afford it.
