ledger_pulse | XRP Ledger network health right now: latest validated ledger, close time, transactions and payments in it, fee levels, load, and rolling averages cross-checked against a direct ledger read. Useful before submitting XRP Ledger transactions or when reporting current network conditions. The first call each day returns the real answer without payment. After that, about $0.001 via x402 (USDC on Base, o params: none |
payment_check | Verifies that an XRP Ledger payment settled as expected: validation, result code, destination, destination tag, currency, issuer, and the amount actually delivered, which exposes partial-payment tricks. Useful when confirming that a customer or counterparty really paid. The first call each day returns the real answer without payment. After that, about $0.01 via x402 (USDC on Base, or XRP / RLUSD o params: tx*, network, destination, amount, currency, issuer, destination_tag |
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 params: account* |
token_check | Identifies one XRP Ledger token from the validated ledger: a trust-line token (currency code plus issuer) or a multi-purpose token (48-hex issuance id). Reports the type, issuer domain check, supply, and controls that can freeze, lock, claw back, or restrict holders. Issuer-written metadata is quoted and is not treated as fact; a missing asset class is reported missing. Does not check other chains params: mpt_issuance_id, currency, issuer |
large_payments | Lists large XRP Ledger payments (50,000+ XRP or major stablecoins) in a recent window of up to 120 minutes, each independently re-checked on the ledger, with an explicit note when the window is not fully covered. Useful for market and liquidity monitoring. The first call each day returns the real answer without payment. After that, about $0.02 via x402 (USDC on Base, or XRP / RLUSD on the XRP Ledg params: minutes, min_value, limit |
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. For a multi-purpose token, pass mpt_issuance_id instead of currency and issuer. Returns ok_to_send, send_with_caution, or will_fail with re params: destination*, amount, currency, issuer, destination_tag, source, network, mpt_issuance_id |
payment_watch | Payment arrival alert: watches an XRP Ledger address for up to 24 hours and POSTs a signed webhook when a matching payment is final (validated, tesSUCCESS, delivered amount checked), or a watch.expired event if none arrives. Payments that land during restarts are still caught. Useful when waiting on an incoming payment without polling. The first call each day returns the real answer without paymen params: address*, webhook*, destination_tag, min_amount, currency, issuer, hours, network |
receipt_card | Verified payment receipt image (1200x675 PNG) for an XRP Ledger payment, drawn only from the validated ledger: delivered amount, sender, recipient, destination tag, ledger, close time, result, optional expectation checks, and a QR code to the public explorer. Only final outcomes are drawn; not-found or unvalidated transactions are not charged. Useful for showing a person proof that a payment arriv params: tx*, network, destination, amount, currency, issuer, destination_tag |
ledger_moment | Ledger moment image (1200x675 PNG): one validated XRP Ledger ledger drawn as one tile per transaction in ledger order, colored by type (payments, DEX offers, trust lines, AMM, NFTs, other), failed transactions hollow, with counts, fees burned, XRP supply, and the ledger hash.

free_send_check | Free, one per user per day.

Returns the verdict, blockers, and cautions from a validated ledger. The paid send_check adds the full evidence and has no daily limit. params: destination*, amount, currency, issuer, destination_tag, source, network |
